摘要: 在超声波作用下,熔融挤出制备丙烯基塑性体(DP) /纳米SiO2复合材料,并研究了超声波对复合材料微观形貌、动态力学性能和结晶性能的影响。结果表明:纳米SIO2的加人提高了DP的储能模量,降低了耗能模量,并促使PP在更高温度下结晶,结晶烩变小。而超声波的引入有助于纳米SiO2在DP基体中均匀分散,导致复合材料的耗能模量升高,但降低了储能模量和玻璃化转变温度,同时复合材料的结晶温度提高,结晶熔下降。

Abstract: By the aid of ultrasonic vibration, a novel propylene based plastomer (DP)/nano-SiOz composits was prepared by means of melt blending. The effects of ultrasonic wave on morphology, dynamic mechanical properties, and crystallization properties of the composite were studied. Ultrasonic vibration promoted the dispersion of nano-SiO2 in DP matrix, thus increased the storage modulus and decreased of loss modular. In addition, the presence of nano-Siq increased the crystallization temperature, however,the crystallization enthalpy decreased
