| 제목 | Characterization of PBS-urethane-silica nanocomposites prepared by in-situ polymerization |
| 초록 | Poly(butylene succinate) (PBS) is a aliphatic thermoplastic polyester, which is a promising polymer for degradable plastic and biomaterials.1 However, processability of PBS, such as softness and melt viscosity for further processing etc., are often not sufficient for various end–use applications.2 Biodegradable polymer/inorganic nanocomposites are one of the methods for improving these problems. Strong adhesion between inorganic particles and polymer play a key role for the properties of biodegradable polymer/inorganic nanocomposites.3 This strong interfacial adhesion can be induced by chemical bonding, such as urethane bonding, between inorganic material and organic matrices. Therefore, in this study, Hexamethylene diisocyanate (HDI), which can bond chemically with hydroxyl groups of chain-end of PBS was used as surface modifier of fumed silica. Isocyanate group introduced on the surface of silica, was confirmed by FT-IR and Solid-state 29Si-NMR spectroscopy. PBS-silica nanocomposite was prepared by in-situ polymerization. Then, thermal, mechanical and rheological properties of prepared PBS-silica nanocomposites were measured by DSC, the tensile testing machine (Instron Corp.), and ARES, respectively. References 1. E.
