Abstract

The role of conductive fillers in the physical and chemical properties of composite materials based on poly(styrene-butadiene-styrene) is studied in comparison with the neat matrix. Using a three-stage extrusion method, composite materials are produced with the addition of a filler: silver or aluminum particles at a concentration of 1, 5, and 10 wt %. The structure of the composite materials is studied using wide-angle and small-angle X-ray scattering methods. The domain organization of the materials is revealed. The sizes of the filler crystallites and the value of the typical scattering order of the block copolymer is defined. Based on scanning electron microscopy data, the sizes of the filler particles and their distribution throughout the volume of the composite materials are estimated. It is found that the introduction of up to 10 wt % filler has low effect on the mechanical behavior of the composite materials compared to a polymer matrix, but changes their electrophysical properties. The principal possibility of using the obtained composite materials for 3D printing is demonstrated.

基于银和铝颗粒的聚(苯乙烯-丁二烯-苯乙烯)3D打印复合材料
研究了导电填料对聚苯乙烯-丁二烯-苯乙烯基复合材料理化性能的影响,并与纯基体进行了比较。采用三段式挤压法,复合材料是在添加填料的情况下生产的:浓度为1、5和10 wt %的银或铝颗粒。利用广角和小角x射线散射方法研究了复合材料的结构。揭示了材料的畴组织。确定了填充晶的尺寸和嵌段共聚物的典型散射阶数。根据扫描电镜数据,估计了填料颗粒的尺寸及其在复合材料中的分布。研究发现,与聚合物基体相比,添加10%的填料对复合材料的力学性能影响较小,但会改变复合材料的电物理性能。论证了将所获得的复合材料用于3D打印的主要可能性。
