As the spread of the bacteria increases, interest in antibacterial products is increasing. It is also essential to the materials inside automobiles. Copper sulfide(CuS) is known to have antibacterial and deodorizing effects. In this study, antibacterial PP/CuS/Talc composites were prepared by melt mixing method. The crystallization behaviors were measured by a non-isothermal crystallization method. Tensile and flexural modulus of composites increased about 60% as compared with a pristine PP. The antibacterial activity of composites was 3.0(99.9% level of antibacterial activity) adding a small amount of CuS. The degree of crystallinity of PP/CuS significantly increased and the crystallization rate was faster than pristine PP, thereby CuS acts as an antibacterial and nucleating agent. |
