Abstract

ABSTRACT: Poly(propylene carbonate) (PPC) was reinforced by polyamide 66 short fiber (SF-PA66) through hydrogen-bonding interaction. The tensile and impact strength, thermal stability of composites increased when the SF-PA66 content ranges from 5 to 20%, then decreased at 30%. The increment in impact strength, decomposition temperature of 5% mass loss and glass transition temperature of PPC/20%PA66 is 315.81%, 32.2 and 3.8°C, respectively. Fourier transform infrared spectroscopy and proton nuclear magnetic resonance spectroscopy results illuminate that the introduction of hydrogen-bonding interaction between PPC and SF-PA66. Moreover, the network structure formed when SF-PA66 content is higher than 20 wt%. It is confirmed by rheological responding curves that a plateau at low angle frequency occurs. In addition, a significant aggregation of SF-PA66 occurs when its content is 30 wt%, which causes the decrease in mechanical and thermal properties of PPC/SF-PA66 composites. GRAPHICAL ABSTRACT:
