Thermo-mechanical processing of chitosan provides an industrially viable alternative to solvent casting technique. Using cyclic carbonates as green plasticizers improves the tensile strength and antimicrobial properties of plasticized chitosan films with good reprocessability without lessening the tensile and tear properties.

Schematic representation of the four types of chemical modifications for chitin and chitosan fibers and filaments: graft polymerization, hydroxyl group modification, amine group modification, and N-acetamide group modification, including examples of specific chemical modifications.

Here the one-pot synthesis and self-assembly of polyethylene-glycol-based amphiphilic polythiourethanes consisting of a pendant methyl or aromatic ester are reported. Introducing an aromatic pendant group enhances the stability and dye-loading ability of the polymersomes. This phenomenon is unraveled studying the evolution of fluorescence resonance energy transfer (FRET) by encapsulating donor–acceptor chromophore.

The graphical abstract depicts importance of mode of nanofiller additions for an enhanced piezoelectric property of the PVDF matrix. The novel approach of ZM_x Nanocomposite filler additions brings out better piezoelectric behavior at material-device levels in comparison to conventional Z/M_x Hybrid fillers in polymer. The possibility of using of ZM_x Nanocomposite-Polymer nanocomposite films for potential sensing applications is further explored.

The present study presents the upcycling of rice straws into a valuable all-cellulose-based aerogel through phosphorylation, serving as an alternative to traditional absorbent layers in sanitary pads. The aerogels produced demonstrate impressive water absorption, thermal stability, porosity, and biodegradability. The aerogels also demonstrate a prolonged storage and release profile of clotrimazole, demonstrating a synergistically strong antifungal effect against Candida species.

This study describes the creation of a bioplastic used in sustainable food packaging that is made of chitosan, silver nanoparticles, and extract from Indian gooseberries. It has excellent mechanical strength, flexibility, and antibacterial qualities. It is also a potent Ultraviolet (UV) blocker.

This study investigates the development of biodegradable PHB/KS composites with enhanced barrier, mechanical, and antimicrobial properties for food packaging applications. The composites demonstrate improved performance by reducing microbial contamination, maintaining food freshness, and exhibiting superior tensile strength and degradation profiles. The findings offer a sustainable alternative to traditional packaging materials, addressing environmental concerns and food safety challenges.

Various side chains (hydrophilic and hydrophobic) affect molecular packing of random polymers which ultimately affects its thin film morphology and semiconducting performances. Linear chains provide better interchain packing by π–π stacking compared to bulky branched side chains. The incorporation of heteroatoms and polar groups into the side chain further enhances the interchain interactions.

This study reports the development of polydopamine-modified rice-straw-derived cellulose nanocrystal-based adsorptive nanocomposite membranes for the removal of cationic dyes from water. The developed membrane achieves excellent dye removal efficiency, can easily be regenerated, and reused with higher performance even after multiple adsorption-desorption cycles. The membrane showed great potentials as a low-cost and environmentally friendly material for the efficient removal of cationic dyes from water.

Molecular dynamics simulations explore polymer membranes, revealing detailed drug binding sites and interaction mechanisms with pharmaceutical compounds. These studies provide insights into drug release, transport, and stability within gastro-intestinal buffers, advancing drug delivery system design and optimization.

This study presents the design of a cost-effective thiourea-based racemic organocatalyst for stereoselective ring-opening polymerization of racemic lactides. The synthesized polylactides showed moderate tacticity, with a Pm value ranging from 0.71 to 0.78. The bulk structure of the synthesized polylactides revealed that the PLA synthesized from rac-lactide and [(rac-TU)Me] catalysts resulted in a tapered stereoblock structure exhibiting stereocomplex characteristics.
