AI Technical Summary

Technical Problem

Existing biodegradable resins, particularly polylactic acid, are prone to degradation under normal usage conditions when in contact with decomposition accelerators, and their biodegradability is not optimized in decomposition-accelerating environments.

Method used

Particles composed of a porous structure mainly of cellulose and cellulose derivatives, with controlled volume-average particle size, BET specific surface area, degree of hydrophobicity, and decomposition accelerator content, are used in a biodegradable resin to suppress degradation under normal conditions and enhance biodegradability under accelerated decomposition conditions.

Benefits of technology

The particles provide a resin molded article that is less prone to degradation under normal conditions and exhibits improved biodegradability in decomposition-promoting environments, with enhanced heat resistance and uniform dispersion.
