Insights into Seawater Biodegradation of Sustainable Mater-Bi/Poly(ε-caprolactone)-Based Biocomposites Filled with Diisocyanate-Modified Cellulose Particles

Due to rapid economic growth, the use of plastics in almost all areas human life has significantly increased over recent decades, leading massive pollution. Therefore, works dealing with sustainable and biodegradable polymer materials are vital now. Herein, Mater-Bi/poly(ε-caprolactone) (PCL)-based biocomposites, filled diisocyanate-modified cellulose particles, were prepared subjected 12-week seawater degradation. Changes chemical structure surface wettability pointed increasing hydrophilicity time, which was limited by diisocyanate modifications. Only minor changes thermal performance analyzed have been observed, pointing biodegradation PCL phase. The most significant effects related composite yellowing due filler modifications erosion its roughness. Obtained results low degradation rate bring into question commonly-regarded nature material.
