Finland's successful research and development can replace new plastic materials: artificial synthetic spider silk can drop

Recently, according to foreign media reports, a study published by Aalto University in Finland in the "Science Progress" magazine pointed out that they used wood fibers and artificial spider silk to develop new bio-based materials, which have high strength , High rigidity and high flexibility and other characteristics, performance is better than most of today's synthetic and natural materials.

The research team of Aalto University in Finland said that it can be used as a substitute for plastics in the future for medical treatment and textiles. Unlike plastic, wood fiber and spider silk have the advantage that they are biodegradable and environmentally friendly.

The researchers first broke the birch pulp into fine fibers and built a hard fiber network, infiltrating the spider silk fibroin binder into it, and finally made the material.

At the same time, the researchers said that the spider silk used in the research was not extracted from the spider web, but artificial spider silk. The chemical properties of the silk protein molecules in the spider web were similar to the silk protein molecules in the spider web.

Currently, the team is working on the development of new composite materials, such as implantable items and impact-resistant objects.
