- Abstract
- A series of poly(butylene succinate)/silica (PBS/silica) nanocomposites were prepared by in situ polymerization. Solid-state Si-29 NMR and FTIR analysis indicated that silanol-bonded carbonyl groups are established within PBS/silica nanocomposite materials. Rheological effects inherent to the silica filler were evaluated by melt theological analysis as a function of shear force in the molten state. Despite high shear force, PBS/silica nanocomposites maintained a relatively high melt viscosity, attributable to a network structure resulting from covalent bonding between silica and the polymer chain. Nanocomposite material containing 3.5 wt% silica exhibited greatly improved mechanical properties. The tensile strength at break and elongation were ca. 38.6 MPa and 515%, while those of the parent PBS were 26.3 MPa and 96%, respectively. PBS/silica nanocomposites showed composition dependency on biodegradation ascribable to reduced crystallinity and preferential microbial attack. (C) 2008 Elsevier Ltd. All rights reserved.
