The biomass-based copolymer, composed of hydroxymethylfurfural (HMF) and furfural, which are both derived from cellulose and hemicellulose, proved its effectiveness against UV radiation thanks to its bisfuran structure. This structure prevented the UV rays from penetrating the material’s film — a feature that was previously not achievable in carbon-based plastics or other recently developed bioplastics.

Both transparent and airtight, researchers believe the material will protect packaged products — such as food — from direct sunlight. Additionally, the team also envisions that the material will be used to construct chassis materials capable of protecting electronics from sun damage as well.

The study was published in the journal Biomacromolecules.
