In this study, cellulose was successfully purified from sugarcane bagasse by alkali treatment and bleaching process. Then, 2-10 wt% of added into polyethylene glycol acrylic acid-based hydrogel composite. 25 kGy gamma irradiation dose employed to form the gel. With presence various contents, no significant change functional group therefore observed. The composite thermally resisted up 250°C. microstructure exhibited as an interconnected porosity throughout network. Cellulose located inside...
This research aimed to scale up the production of starch-based super water absorbent (SWA) and validate practical benefits SWA for agricultural applications. was successfully prepared in an up-scaling by radiation-induced graft polymerization acrylic acid onto cassava starch. Chemical characterization FTIR thermal TGA showed results that differentiated starting materials from SWA, thus confirming effective preparation via polymerization. SEM visibly revealed a highly porous morphology...
Polymer nanocapsules containing fragrance were fabricated for antibacterial, pleasing scent and UV-coating applications. Poly (2-methacryloyloxy dodecyl dimethyl ammonium chloride-4-allyloxy-2-hydroxybenzophenone)-block-polymethyl methacrylate-iodide (P(QAC12-BP)-b-PMMA-I) was first synthesized by solution iodine transfer polymerization (solution ITP) use as a polymerizable surfactant in miniemulsion where benzalkonium chloride (BKC) used cosurfactant. The prepared using poly(methyl...
This study presented a green, facile and efficient approach for new combination of targeted gold nanohybrids functionalized with folate-hydrophobic-quaternized pullulan delivering hydrophobic camptothecin (CPT-GNHs@FHQ-PUL) to enhance the efficacy, selectivity, safety these systems. New formulations spherical CPT-GNHs@FHQ-PUL obtained by bio-inspired strategy were fully characterized TEM, EDS, DLS, zeta-potential, UV-vis, XRD, ATR-FTIR analyses, showing homogeneous particles size an average...
This research focuses on developing a new method to fabricate water super-absorbent polymer (SAP) beads via spherification and radiation-assisted polymerization. The effects of parameters such as pH, concentration monomer, presence cassava starch well radiation dose gel fraction swelling ratio were investigated determine an optimum condition. Chemical physical properties the prepared SAP characterized using FTIR, TGA, SEM UTM. Results showed that can be successfully formulated in uniform...
This research investigated and developed a laminate packaging film of poly(lactic acid) (PLA) poly(vinyl alcohol) (PVA) containing modified chitosan nanoparticles (MCSNPs) treated with 3-(trimethoxysilyl)propyl methacrylate silane (TMSPM) which functioned both as reinforcement an antimicrobial filler. Electron beam irradiation caused crosslink between the PVA MCSNP molecules via free radical carbonyl in group TMSPM-grafted hydroxyl alcohol). improved hydrophobicity. In addition, PVA-g-MCSNPs...
Abstract Gamma radiation was used to prepare a natural polymer-based adsorbent via radiation-induced grafting polymerization of acrylic acid (AA) onto carboxymethyl cellulose (CMC). Optimization the process done by varying number parameters from dose amount AA and CMC. Characterization Fourier transform infrared spectroscopy (FTIR) thermogravimetric analysis (TGA) confirmed successful CMC, with maximum efficiency (GE) 94%. The effectiveness graft copolymers for removal two standard dyes,...
The purpose of this work is to study the methyl orange removal Ni(OH)2 nanoparticles. photo-catalyst activity investigated based on UV lamp 18 watt. synthesized by a self-assembly process and then exposed electron beam radiation at 10 MeV energy with various doses ranging from 50 kGy 500 kGy. properties nanoparticles are evaluated. No significant change functional group percent crystallinity observed. morphology uniformly presented as plate-like. specific surface area, pore size volume...
Gel electrolytes based on poly(acrylic acid) and poly(ethylene glycol)diacrylate (PAA-PEGDA-Ca2+) loaded with Ca2+ ions were successfully prepared using gamma irradiation. The use of radiation provides benefits, such as solventless preparation without byproducts. obtained gel fraction, porosity, swelling ratio in the range 60–90%, 11–60%, 4–12 g/g, respectively. Fourier transform infrared spectroscopy confirmed successful crosslinking between PAA PEGDA. Crystallinity remained unaffected by...
Because fossil-based polymer particles are generally not biologically degradable, which has led to their significant accumulations as microplastic is now a serious global problem. Therefore, bio-based polymers synthesized from renewable monomers have received much attention due biodegradability and biocompatibility. The biopolymer in particle forms been recently recognized functional material. Dispersed systems mainly them via radical polymerization. radicals generated by gamma radiation...
