The Enhanced Mechanical Properties of a Covalently Bound Polyurethane/Cellulose Nanocrystal Nanocomposite

摘要

A series of covalently bound PU/CNs nanocomposites were prepared. These grafted-PU chains were able to form a crystalline structure on the surface of CNs, and thus induce the crystallization of the matrix which created a co-continuous phase. Therefore, the incorporation of CNs in PU resulted in a significant improvement in the mechanical properties.
