Biocomposite foams based on polyhydroxyalkanoate and nanocellulose: Morphological and thermo-mechanical characterization.
Abstract
The application of bio-based and biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is restricted by its high cost and brittleness. In the present work, these deficiencies were overcome by the manufacture of PHBV foams using thermally expandable microspheres (TES). Nanocellulose (Nc) and a crosslinking agent were added to PHBV-TES to control the foam structure and to improve the mechanical properties. Foams with almost perfect pores, well embedded in the polymer matrix, were obtained by a simple melt molding process. The closed-cell foams have a density 2.5-2.7 times lower than that of PHBV. The addition of Nc increased the expansion ratio, cell density and porosity and also led to a more uniform cell size distribution. The incorporation of the crosslinking agent, together with Nc and TES, increased the glass transition temperature with about 7 °C and strengthened the PHBV-Nc interactions. PHBV foams showed a 1.7-3 times higher deformation compared to PHBV and absorbed up to 15 times more energy. The fully biodegradable PHBV-Nc foams obtained in this work exhibit an advantageous porosity, good specific mechanical properties and high energy absorption, being promising alternatives for insulation, packaging or biomedical application.
