Sturdy Bioplastic Made of Wood and Spider Silk

Sturdy Bioplastic Made of Wood and Spider Silk
A blend of spider’s silk and cellulose has led to a promising new type of bioplastic.

Researchers from Aalto University and VTT Technical Research Center created the material by arranging birch tree cellulose nanofibrils on a scaffold and infusing them with a lab-made spider silk. The result was a strong yet elastic composite that could be used in packaging, medicine and the textile industries.

The team also believes the technique could be expanded to manufacture different composites for specific applications, such as implants or impact-resistant materials.
