Unexplored possibilities of all-polysaccharide composites

Area of Science:

• Materials Science
• Polymer Chemistry
• Biotechnology

Background:

• Traditional composites often rely on synthetic polymers, posing environmental challenges due to non-biodegradable residues.
• All-polysaccharide composites (APCs) present a sustainable and ecological alternative, leveraging the natural biodegradability of polysaccharides.
• A wide array of polysaccharides, including cellulose, chitin, chitosan, and starches, can be utilized in composite formulations.

Purpose of the Study:

• To comprehensively review existing literature on all-polysaccharide composites (APCs).
• To categorize and discuss various types of APCs based on their polysaccharide components.
• To highlight the potential applications and unexplored combinations of APCs.

Main Methods:

• Literature review of all-polysaccharide composites.
• Categorization of composites based on polysaccharide composition (e.g., all-cellulose, cellulose-polysaccharide blends, chitin/chitosan-based).
• Analysis of tested properties including absorptivity, biodegradability, mechanical strength, and antimicrobial activity.

Main Results:

• APCs are predominantly ecological, degrading without harmful residues.
• A broad spectrum of polysaccharides can form composites, including cellulose, chitin, chitosan, heparin, and starch.
• Tested properties encompass absorptivity, biodegradability, mechanical, optical, and antimicrobial characteristics, among others.
• Composites utilizing more than two polysaccharide types are rare, except in food applications, indicating significant unexplored potential.

Conclusions:

• All-polysaccharide composites offer a sustainable and versatile material class with broad application potential.
• Further research into novel combinations of polysaccharides can unlock new material properties and functionalities.
• The development of APCs is crucial for advancing eco-friendly materials in diverse industries.
