| 제목 | Physical and Mechanical Properties of Plasticized Butendiol Vinyl Alcohol Co-polymer/Thermoplastic Starch Blend |
| 초록 | The poly(vinyl alcohol)(PVA) is an eco-friend polymer and has an excellent oxygen barrier property due to its strong intermolecular force, but difficulty in processing with conventional extrusion process gives it a limitation for various industrial applications, especially packaging industry. Therefore, PVA often blended with other biodegradable polymers such as starch. Nowadays, the butendiol vinyl alcohol co-polymer (BVOH) is getting a great attention due to its melt processability. In this study, BVOH/thermoplastic starch (TPS) were prepared by melt mixing technique. The plasticization effect of glycerol on BVOH and TPS with different composition was observed for better processability. Based on preliminary result, BVOH and TPS containing glycerol 10 and 15 phr, and 25 and 30 phr, respectively were selected. Then, each type of BVOH was blended with varying amount of each type of TPS (0:100, 10:90, 20:80, 30:70, 40:60 and 50:50 weight ratio). Physical and mechanical properties of the blends were evaluated by various analytical instruments to achieve optimized property and performance. |
