Nano Reinforcements for Polybutylene succinate Biocomposites |
| 초록 |
Biocomposites made of natural fiber reinforcement and biodegradable polymer matrix has been studying actively in order to develop environmentally friendly material for application of automobile industry, etc. Biocomposites is lightweight and has comparable mechanical properties to glass fiber reinforced polymer composites. Also, biocomposite may be readily recycled and contributes to atmospheric CO2 reduction. Researches for enhancement of the mechanical properties and solution for some drawbacks of biocomposite such as dimensional stability are ongoing and trying to find the solution with the combination of nano technology. We have studied the nano reinforcements effect on the thermal and mechanical properties of biocomposites. The reinforcements considered are carbon nanotube(CNT), silk nanofiber(Silk-NF) and cellulose nanofiber(Cel-NF). Carbon nanotube was prepared by thermal pyrolysis in the ranged with 800~900oC and purified by HCl and HNO3. CNT is mutiwalled and the inner diameter of CNT is ~11 nm with 21 graphitic shells with armorphous carbon of outer shell. Silk-NF from and Cel-NF were prepared from waste silk fiber and cellulose powder, respectively, by electrospinning process. Especially, Cel-NF was obtained using high temperature electrospinning process. The diameter of nano fibers is ~100nm. Polybutylene succinate(PBS), biodegradable polymer, is used to enhance the environmentally friendliness of biocomposites. The thermal, thermomechnical and dynamic mechanical properties of biocomposites were compared. The present results suggest that use of nanofiber and CNT as reinforcements of biocomposites may be very useful for effectively improving the mechanical and thermal properties of polymer matrix or biocomposite reinforced with natural fibers. |
