As growing concern for environment of the earth increased, many researches and developments about eco-friendly material have been made. Biodegradable polymers have received much attention in recent years as one of the approaches to solve the problem. The bio-composite is the key of green material and we used a kind of the biodegradable polymer as the matrix and natural fiber as the corporative filler in this study. Among the biodegradable polymers, polylactic acid(PLA) has excellent characteristics such as biodegradability, good stiffness, transparency etc. However, PLA has intrinsic shortcomings like brittleness, poor impact strength. So as to solve like these problems, PLA compounded with other suitable biodegradable polymer which has better flexible, bending properties and excellent impact strength will be modified to various properties and contribute to many applications. In this presentation, the mechanical properties, miscibility and thermal properties will be discussed. |
