Renewable and biodegradable cellulose-based materials are attractive alternatives to petroleum-based plastics, yet their performance is often limited by strong hydrogen bonding. Herein, we report high-performance fully bio-based cellulose plastics (FBCPs) prepared through a facile one-pot reaction of cellulose with epoxidized linseed oil in a CO2-switchable solvent. The resulting dual cross-linked network synergistically enhances mechanical properties, yielding an optimal FBCP with a tensile strength of 31.1 MPa, elongation at break of 217.9 %, and toughness of 62.2 MJ m-3, surpassing many reported cellulose-based materials and commercial plastics. The material also exhibits excellent hydrophobicity (water contact angle of 107.1o) and retains a toughness of 23 MJ m-3 in the wet state. Moreover, FBCPs completely degrade in ambient soil within 50 days, demonstrating a compelling combination of high performance and environmental sustainability.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
