Abstract
Polylactide-graft-γ-methacryloxypropyltrimethoxysilane (MPS-g-PLA) was prepared by grafting MPS onto PLA. MPS-g-PLA was characterized by Fourier transform-infrared spectroscopy (FT-IR), hydrogen nuclear magnetic resonance (1H-NMR), and gel permeation chromatography. Furthermore, MPS-g-PLA was used to modify bacterial cellulose (BC), and the changes of surface properties of BC resulting from the treatment were followed by FT-IR and contact angle measurements. The results revealed that the modified BC possessed a much more hydrophobic nature than virgin BC. The surface modification of BC with MPS-g-PLA offers a way to increase the compatibility between the components in biocomposites, and thereby to improve the properties of these composites.
