Green bionanocomposites based on polyhydroxybutyrate and filled with cellulose nanocrystals: melting processing and characterization

Autor: Anja Schmidt, Birgit Bittmann-Hennes, Belén Montero, Bernd Wetzel, Luis Barral

This article contributes to the understanding of biobased and biodegradable polyhydroxybutyrate (PHB) bionanocomposites reinforced by weight contents of 1 wt% and 3 wt% of cellulose nanocrystals (CNC), which are derived from waste streams of the pape

Publikováno v: Green Chemistry. 23:2198-2232

The hierarchical, porous, and macromolecular structures of woods provide opportunities for them to be modified and processed into structural, functional, and multi-functional materials. Chemical and thermal modifications are usually applied to adapt
