초록

Polyamide 66 (PA66) and thermotropic liquid crystalline polymer (TLCP) were added to poly(phenylene sulfide) (PPS) using a twin screw extruder via a melt blending method, and the effect of PA66 and TLCP addition on the properties of the PPS film was investigated. Differential scanning calorimetry showed that the melting point ($T_m$) and glass transition temperature ($T_g$) of PPS in the PPS/PA66 and PPS/TLCP blends were unaffected by the addition of PA66 and TLCP, even up to 20 wt%. However, the addition of PA66 or TLCP affected both the cold and melt crystallization temperatures. SEM of the fracture surfaces of the two blends with various compositions revealed PA66 and TLCP as spherical particles in the blends, indicating that both PPS/PA66 and PPS/TLCP are immiscible blend systems. The addition of up to 20 wt% PA66 did not affect the mechanical properties of the resulting PPS/PA66 blend films. On the other hand, the addition of up to 10 wt% TLCP increased the tensile strength slightly. The tensile strength retention of the blend films immersed in an aqueous solution containing either 30% NaOH, 10% HCl or 10% $HNO_3$ at $93^{\circ}C$ for one week was unaffected by PA66 and TLCP blending.
