BIODEGRADABLE POLYMERS. PART1: POLYMERS FROM NATURALLY RENEWABLE RAW MATERIALS

Polymer journal, Год журнала: 2025, Номер 46(4), С. 243 - 258

Опубликована: Апрель 7, 2025

At the current stage of science and technology development, production biodegradable polymers (BPs) polymeric materials (BPMs) for general industrial, agricultural, or household applications has become highly relevant. These retain their properties throughout service life and, upon its completion, gain ability to decompose under influence natural factors, integrating into metabolic processes biosystem. This review analyzes scientific technical literature from past decade on materials. The classification is provided based type degradation: capable complete mineralization, such as (cellulose, starch); synthetic prone biological degradation (polyesters, polyamides); subject erosion, blends polymers. types BPs are summarized according origin raw methods synthesis. serves foundation series articles dedicated first part focuses BPMs derived naturally renewable sources - that integral living plant animal organisms. Emphasis placed polysaccharides proteins. Among polysaccharides, provides a detailed examination cellulose derivatives (ethers, acetates, nanocellulose); starch (including thermoplastic chitin derivative chitosan; pectins; alginic acids. proteins, animal-derived proteins collagen gelatin, well plant-derived protein soybean discussed. For each these substances, molecular structure, physicochemical properties, production, fields application, mechanisms in nature presented. Using an example, strategy creating cellulose-containing proposed correlation between structure derivatives. 98 publications, concluding offer environmentally safer alternative traditional plastics made petroleum petrochemicals.

Review on Some Important Research Progresses in Biodegradable Plastics/Polymers

Recent Progress in Materials, Год журнала: 2024, Номер 06(02), С. 1 - 19

Опубликована: Июнь 27, 2024

Biodegradable plastics/polymers may serve as a promising solution to the global problem of plastic waste accumulation in oceans and soil significantly reduce carbon emissions from manufacturing process, since materials used make biodegradable polymers are carbon-based emitted during synthesis processes. This article systematically reviewed existing closely related scientific literature on materials, biomaterials, find answers how effectively study develop polymers. summarized source classifications plastics. Some major techniques for making polymer products were discussed, including micro-extrusion biofibers, solvent casting method thin films, 3D printing, injection compression molding extrusion processes, well fabrication methods applied some important biopolymers, such cellulose, starch, bacterial concrete, packaging paper-based materials. More importantly, experimental computational methodologies characterization development that can be adopted characterize properties understand physicochemical mechanisms described detail, (physical chemical methods) at different scales (from quantum mechanics subatomic scale, molecular dynamics atomic finite element analysis micro or macro scale), data methods. The degradation factors affecting biodegradability discussed. Finally, future perspective has been described. Properly adopting effective state-of-the-art biomaterial research (experimental advanced discussed this will help advance novel
