Bioinspired green composite lotus fibers

Area of Science:

• Materials Science
• Biomaterials Engineering
• Sustainable Composites

Background:

• Increasing global environmental concerns drive demand for sustainable, biodegradable materials.
• Traditional composite materials often lack environmental friendliness and biodegradability.
• Bio-inspired designs offer novel solutions for material development.

Purpose of the Study:

• To fabricate a fully green composite fiber (GCF) inspired by cocoon silk structure.
• To investigate the potential of lotus fiber (LF) and poly(vinyl alcohol) (PVA) for creating sustainable composites.
• To evaluate the mechanical properties of the developed GCF.

Main Methods:

• Fabrication of a GCF using lotus fiber (LF) and poly(vinyl alcohol) (PVA).
• Formation of cross-linkages between LF and PVA to enhance material properties.
• Characterization of the mechanical properties of the bioinspired GCF.

Main Results:

• The fabricated GCF demonstrated significantly improved mechanical properties after cross-linkage formation.
• The specific mechanical properties of the GCF were found to be superior to cocoon silk and other natural fibers.
• The study successfully created a fully green and biodegradable composite fiber.

Conclusions:

• Lotus fibers (LF) show significant potential as reinforcement materials for bulk green materials.
• The developed GCF offers a sustainable and high-performance alternative for industries like textiles, medical, automotive, and aerospace.
• This research contributes to the development of environmentally friendly materials addressing global sustainability challenges.
