Uv-shielding biopolymer film for agrochemical protection
Innovative biopolymer film using proteins and polysaccharides with UV-protective chromophores to shield agrochemicals from UV damage. Utilizes sustainable materials like lignin and curcumin for effective protection in the 280-420 nm range. Developed through protein-ligand docking simulations.
Overview
This UV-shielding biopolymer film is designed to protect agrochemicals from UV-induced degradation after field application. It combines alcohol-soluble proteins and polysaccharides with UV-protective chromophores, such as lignin and curcumin, to block harmful UV radiation within the 280-420 nm range. The film is fabricated using a sustainable approach, leveraging biocompatible plasticizers for safety and environmental compatibility.
Technical specifications
- Composition: Alcohol-soluble proteins (zein, gliadin) and polysaccharides (ethyl cellulose, propylene glycol alginate) plasticized with glycerol and sorbitol.
- UV Protection: Enhanced with chromophores (lignin, curcumin, quercetin, rutin) for effective UV shielding.
- Fabrication Process: Components dissolved in alcohol-water mixtures, cast onto substrates, followed by controlled solvent evaporation to form uniform films.
- Optimization: Protein-ligand docking simulations used to improve component synergy and mitigate antagonistic interactions.
Technology readiness level
Currently at TRL 2, the technology is in the early stages of development. Future validation steps include formulation design, biopolymer synthesis, sprayable formulation optimization, and UV protection efficacy assessment over an 18-month period.
