摘要
电气石因其具备释放负离子辐射远红外线等保健功能受到广泛关注,可作为填料添加到聚合物复合材料中。先用改性剂山梨醇酐单硬脂酸酯(Span-60)对电气石粉进行表面有机改性,改善了电气石表面的亲油性,通过熔融共混法制备了热塑性淀粉(TPS)/聚己二酸对苯二甲酸丁二酯(PBAT)/电气石复合材料。实验结果表明,随着改性电气石含量的增加,TPS/PBAT/电气石复合材料的拉伸强度和弹性模量均先升高后降低,当电气石含量为3%的时候,电气石在基体中的分散稳定性最好,复合材料的拉伸强度和弹性模量达到最大,分别为13.22MPa和346MPa;且TPS/PBAT/电气石复合材料具有优异的负离子释放功能,较高的远红外辐射率,其远红外辐射率达到0.95以上。
