Now polymer technology, one step further of a basic roles, maximize facileness of people and plays a role in providing opportunities that can coexist between mankind and natures. Bio-plastics based polymeric materials have been studied from various viewpoints. Particularly around the PLA, various studies was promoted for its preparation and application. Among them, bio-screw with biodegradable properties, led to innovations in the medical industry. The screw allow new concept of the surgery that need no secondary surgery. Carbon dioxide-based polymeric material, a new type of material which can be expected the Carbon capture & storage effects throughout the process of the synthesis and its applications. PEC (poly ethylene carbonate) and PPC (poly propylene carbonate) are representative cases. These carbon dioxide-based polymer material has various limitation in a single material, so many kinds of research are progressed to overcome the drawback. |
