Abstract

New bacterial cellulose (BC)/poli(3-hidroxibutirate) (PHB) biocomposites were prepared by soaking never previously dried BC in PHB chloroform solution. SEM analysis revealed a completely homogeneous coating of BC micro fibril by PHB deposition. The thermal behavior (TG and DSC curves) of BC-PHB composites were observed to have predominance of BC characteristics, and FT-IR spectra of BC/PHB composites are considered as the result of the convolution of the spectra of two materials. Biocomposites based in these polymers may find practical application where properties such as biodegradability are desired.
