Article
Full-text available
Three bio-based aerogels were prepared using a cross-linked blend of gelatin and different ratios of poly(amidoamine) hyperbranched polymer (PAMAM) via freeze-drying technique. These aerogels are assigned as cGel/PAM 1, cGel/PAM 2, and cGel/PAM 3. Aerogel of cross-linked gelatin cGel was prepared for comparison. The fabricated aerogels were charact...
Article
The present research focuses on developing highly efficient, low-cost, and eco-friendly bio-sorbents based on lingo-cellulosic materials in oak wood sawdust waste. Sawdust was chemically modified using poly (amido amine) PAMAM as an active polymer and epichlorohydrin as a cross-linker. The chemical composition and surface morphology of resulting so...

Full-text available
Extracted gelatin from the waste of fresh and grilled chicken skin was used to prepare films as a biodegradable packaging material from solutions of various gelatin concentrations using a casting approach. The thermal behavior of extracted gelatins was investigated by differential scanning calorimetric. The particle size and zeta potential of dispe...
Article
Acyclic diene metathesis (ADMET) copolymerization of dianhydro-D-glucityl bis(undec-10-enoate) (M1) with 1,9-decadiene (DCD) using ruthenium-carbene catalyst, RuCl2(IMesH2)(CH-2-OiPr-C6H4) [IMesH2 = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene, HG2], afforded unsaturated polyesters (Mn = 9300–23,400) under the optimized conditions. Subsequent...
Chapter
Textile processing is usually accompanied by high environmental pollution, high energy, water, and chemical-consuming processes. Therefore, the requirements for development of sustainable biopolymers used in textile industry are continuously increased. Biopolymers attracted considerable attention as a new generation of smart textile materials produ...
Article
Acyclic diene metathesis (ADMET) polymerization of biobased α,ω-dienes of bis(undec-10-enoate) with diols (1,4-butanediol, isosorbide, isomannide, and 1,4-cyclohexanedimethanol) afforded high-molecular weight unsaturated polyesters, and subsequent tandem hydrogenation (H2 1.0 MPa, 50 °C, 3 h) gave the saturated polymers upon addition of a small amo...
Article
Full-text available
Magnetic aerogels were prepared via physical cross-linking of Iota-carrageenan and polyamidoamine (PAMAM) dendrimer using different amounts of magnetic nanoparticles (1, 3 and 5%). A blank sample of chemically cross-linked Iota-carrageenan was prepared for comparison. The prepared magnetic nanoparticles and aerogels were fully characterized using p...

Full-text available
N-vinyl imidazole (NVI) was grafted onto gelatin using potassium persulphate (KPS) as thermal initiator in aqueous medium. The effects of various parameters such as different KPS and NVI concentrations, the time and reaction temperature on the grafting process have been investigated. The optimum conditions were found to get the highest grafting eff...
Article
Full-text available
Iota-Carrageenan (i-carrageenan) was cross-linked with Polyamidoamine hyperbranched polymer generation 1 (PAMAM). The resulted hydrogels were dried using freeze-drying technique to give new bio-based i-carrageenan aerogels. These aerogels were characterized using FT-IR and their nitrogen contents were determined using Kjeldahl method. The morpholog...
Article
Full-text available
New low-molecular-weight gelators based on l-phenylalanine derivatives bearing long alkyl chains with different lengths were synthesized via one synthetic step. These gelators [i.e. 1 and 2] were nontoxic, biodegradable and prepared using naturally occurring starting materials. The gelation ability was investigated using different solvents and oils...
Article
Mini emulsified Butylacrylate/Acrylonitrile (BA/AN) copolymer-silica nanoparticles (NPs) nanocomposites were used as functional binder. The prepared nanocomposites contained three different amounts of silica NPs 1, 3, 5 wt%. Two different textile fabrics; cotton fabric 100%, and synthetic polyester fabric 100%; were printed using printing paste con...
Article
Recent results for synthesis of end-functionalized polymers (EFP) by using olefin metathesis polymerization have been introduced including basic characteristics in ring-opening metathesis polymerization (ROMP) of cyclic olefins and acyclic diene metathesis (ADMET) polymerization for synthesis of conjugated polymers. Several approaches were demonstr...
Article
Defect-free, highly trans oligo(2,5-dialkoxy-1,4-phenylene vinylene)s [alkoxy = O(CH2)2OSiiPr3] with both repeat units (ex. 9, 15, and 31 repeat units) and end groups (aldehyde, C6F5, terthiophene, ferrocene) well-defined are prepared by a stepwise combined olefin metathesis using Mo(CHCMe2Ph)(N-2,6-Me2C6H3)[OCCH3(CF3)2]2 with subsequent Wittig-typ...
Article
The precise synthesis of chemically, analytically pure oligo(2,5-dialkoxy-1,4-phenylene vinylene)s [OPVs, alkoxy = O(CH2)2OSi(i)Pr3] with strictly controlled repeat units (up to 15 repeat units) and well-defined end groups has been achieved by a combined olefin metathesis reaction of 2,5-dialkoxy-1,4-divinylbenzene or their derivatives with a molyb...
Article
Here we report the first chiral optofluidic system that enables the emergence and enhancement of chiroptical signals of μm-sized polymer particles from achiral all-trans-poly(9,9-di-n-octylfluorene-2,7-vinylene) (PFV) during mirror-symmetry-breaking aggregation due to the optically active fluidic media consisting of (R)-limonene (1R) and (S)-limone...

Various block (graft) copolymers have been prepared by combination of acyclic diene metathesis (ADMET) polymerization of 9,9-dialkyl-2,7-divinyl-fluorene with Cu-catalyzed atom transfer radical polymerization (ATRP) of styrene using macroinitiators prepared by introduction of initiating functionalities into poly(9,9-dialkylfluorene-2,7-vinylene)s (...

This article summarizes recent examples for precise synthesis of (co)polymers containing functional end groups prepared by living ring-opening metathesis polymerization (ROMP) using molybdenum, ruthenium complex catalysts. In particular, this article reviews recent examples for synthesis of amphiphilic block/graft copolymers by adopting transition...

Homopolymers and copolymers of styrene and butyl methacrylate were synthesized with different ratios by an emulsion polymerization technique with K2S2O8/NaHSO3 as the redox initiation system and sodium dodecyl sulfate as the emulsifier at 60°C for 3 h. The effects of different monomer ratios on the kinetics of emulsion polymerization and polymer vi...
