Abstract

Epoxy resins, despite their unique properties, have limitations in many applications due to their low fracture toughness. One of the most effective methods to overcome this limitation is to use toughening agents, such as carboxyl terminated poly butadiene‐acrylonitrile (CTBN) in the epoxy matrix. CTBN can react with various compounds, such as epoxies. In this study, we investigated the severity of CTBN sedimentation with di epoxy octane (DEO) in the presence basis catalysts. The studied of the physical properties of the synthesized copolymer in the presence of pyridine compared to other catalysts increases mechanical properties (248.43% elongation, 0.63 MPa strength, and 32 hardness with Shore A) and decreases the glass transition temper

Abstract

The story of human dreams about curing all diseases, disorders and lesions is as old as human history. In the frontier of medical science, nanomedicine is trying to solve the problem. In this study, inspired by nanotechnology and using “grafting from” approach, a novel lignin-based nanogel was synthesized using atom transfer radical polymerization (ATRP) method. N-isopropylacrylamide (NIPAM) and N, N-dimethylaminoethylmethacrylate (DMAEMA) comonomers were graft copolymerized from fully brominated lignin as ATRP macroinitiator to synthesize lignin-gP (NIPAM-co-DMAEMA) nanogel (LNDNG). By controlling the initial comonomer compositions and ATRP conditions, four LNDNG systems with different lower critical solution temperatures (LCSTs) of 32

Abstract

Nanogels are crosslinked polymer-based hydrogel nanoparticles considered to be next-generation drug delivery systems due to their superior properties, including high drug loading capacity, low toxicity, and stimuli responsiveness. In this study, dually thermo-pH-responsive plasmonic nanogel (Ng) was synthesized by grafting poly (N-isopropyl acrylamide) (PNIPAM) to chitosan (CS) in the presence of a chemical crosslinker to serve as a drug carrier system. The nanogel was further incorporated with gold nanoparticles (AuNP) to provide simultaneous drug delivery and photothermal therapy (PTT). Curcumin’s (Cur) low water solubility and low bioavailability are the biggest obstacles to effective use of curcumin for anticancer therapy, and these o

Abstract

The periodate modified gum arabic was used as a natural-based, non-toxic cross-linker to synthesize hybrid bovine serum albumin-gum arabic aldehyde (BSA-GAA) nanogels by Schiff base reaction through the inverse miniemulsion method for the first time. The synthesis process was performed in the absence of toxic organic solvents using fractionated coconut oil as the continuous phase. The particle size of the nanogels was managed by tweaking the concentration of the surfactants (Span 80/Tween 80) and the total volume of the aqueous phase. Based on the bicinchoninic acid method, the cross-linking efficiency of BSA and GAA was estimated at 98%. 5-fluorouracil (5-FU) was selected as the sample drug. The 5-FU-loaded hybrid nanogels showed a spheric

Abstract

Abstract PBI: PVPA (Poly (benzimidazole): poly (vinylphosphonic acid)) polymer electrolyte membranes were fabricated with several molar ratios and number-average molecular weights (M? n) of PVPA. Inter-polymer interactions and cross-section morphology of membranes were analyzed using FT-IR and scanning electron microscopy, respectively. Water uptake, proton conductivity, and methanol permeability of the membranes were characterized at several operating conditions. In addition, the influence of doping level of phosphoric acid (H 3 PO 4) on the membranes proton conductivity was investigated. The membranes proton conductivities were enhanced with PVPA molar ratio and M? n. The highest proton conductivity at 150? C, 79.6 mS. cm− 1, was obtain

Journal PapersWood Science and Technology , Volume 54 , Issue 1, 2020 January 1, {Pages 249-268 }

Abstract

Lignin nanoparticles (LNPs) with an average diameter () of 78.2 nm were prepared via rapid pH decrease of alkaline solution to acidic state. Two lignin/silica hybrid (LSH) nanoparticles, ie, LSH1 (= 80.9 nm) and LSH2 (= 83.0 nm), with different lignin contents were synthesized using LNP via sol–gel method and then aminated using 3-aminopropyltriethoxysilane. Polyamidoamine (PAMAM) was then grafted onto the aminated LSHs, resulting in LSHx-PAMAM G1. 0 (x= 1 or 2). Firstly, methyl acrylate was reacted with aminated LSHs. Then, methyl ester groups in the 0.5 th generation were reacted with ethylenediamine (EDA), resulting in the LSHx-PAMAM G1. 0. Structure and functional groups of the bio-based nanoparticles were characterized quantitatively

Journal Papers , Volume 29 , 2020 June 1, {Pages 101299 }

Abstract

Energy Consumption and take advantage of renewable sources become a major concern in last two decades and is being addressed by various researchers to overcome energy challenges. Phase change materials are widely utilized in thermal energy storage systems to resolve energy crises. On the other hand, tendency to phase change materials has many limitations such as liquid leakage during phase transition procedure, low thermal conductivity and low surface area, which affect phase change material thermal performance. Shape stabilization with regard to nano structures is an efficient approach to reduce phase change leakage, improve physical characteristics and thermal performance due to high capillary tension and specific surface area. Shape stab

Journal PapersWOOD SCIENCE AND TECHNOLOGY , 2020 April 15, {Pages }

Abstract

The direct use of lignin results in the synthesis and production of low-value materials. Therefore, the chemical modification of lignin increases not only its reactivity, but also improves its compatibility and better dispersion in the lignin-based polymeric materials where lignin acts as a good substitute for oil-based polyols. Systematic studies were conducted in the present work. Hydroxymethylated lignin (HML) was synthesized via its reaction with formaldehyde, and functional groups present in the sol fraction of HML were then quantitatively investigated by aqueous potentiometric/conductometry titration prior to any further modification and by (HNMR)-H-1 and FTIR techniques after reacting with alpha-bromoisobutyryl bromide, resulting in

A Predictive Thermodynamic-Based Model for Proton Conductivity of Proton Exchange Membranes based on Poly (Benzimidazole)/Poly (Acrylic Acid) Blend

Zohre Taherkhani, Mahdi Abdollahi, Alireza Sharif
Journal PapersJournal of the Electrochemical Society , 2020 May 27, {Pages }

Abstract

To predict the novel poly (benzimidazole): poly (acrylic acid)(PBI: PAA) blend membranes proton conductivity, an ionic conductivity equation combined with thermodynamic model is proposed where different proton transport mechanisms including Grotthuss, vehicle and surface hopping mechanisms are considered in calculations. Based on the PAA titration behavior, by increasing the number-average molecular weight (Mn), apparent acidity of PAA decreases. Hence, to calculate the concentration of protons involved in different mechanisms, a new modification in the predictive model is suggested by considering acidity and its relation with Mn. Effect of temperature, PAA molar ratio and Mn on the membranes proton conductivity is investigated theoreticall

Abstract

To enhance medium/high temperature proton conductivity of poly(benzimidazole) (PBI), phosphoric acid (PA)- doped blend membranes based on the PBI and poly(vinyl imidazole-co-vinyl phosphonic acid) (P(VI/VP)) copolymer were prepared. The proton donor (acid)- acceptor (base) copolymers of P(VI/VP) with defined but different microstructures were synthesized by free radical copolymerization. Tendency of the comonomers towards alternating copolymerization was observed. The blend membranes showed micro- scale phase separated structure due to strong intra-molecular interactions in the copolymer. The effect of alternating diad sequence (i.e. VIVP) fraction as well as blend composition on the membrane proton conductivity was investigated. Results sh
