Elastomeric BionanocompositesBased on High-Elastic"Soft" Polyurethane and High-Crystalline "Rigid"Acetylated Chitin Nanocrystals*
Abstract
Castor oil-based polyurethane bionanocomposites with improved mechanical properties were
prepared by the introduction of crab chitin nanocrystals from partial surface acetylation. Through the controlled acetylation, one part of hydrophilic hydroxyl groups on nanocrystals were replaced by hydrophobic acetyl groups in order to enhance the compatibility between chitin nanoparticles and polyu...
