摘要：

为获得柔性导电纺织材料,采用紫外(UV)光固化技术将还原氧化石墨烯(RGO)印制于棉织物表面。探究了RGO、聚氨酯丙烯酸酯(PUA)、光引发剂1173和三羟甲基丙烷三丙烯酸酯(TMPTA)质量分数及UV光固化时间对棉织物导电性能的影响,测试了整理织物的导电性和导电耐久性,通过扫描电子显微镜分析对整理织物的形貌。研究结果表明,随着RGO质量分数增加,织物的导电性增强,但导电耐久性降低,随着PUA、光引发剂1173和TMPTA质量分数增加及固化时间延长,织物的导电性降低但导电耐久性提高;RGO质量分数增加,织物表面沉积的RGO越多,RGO导电层的连续性提高。当RGO、PUA、TMPTA和光引发剂1173的质量比为10:4:69:17,固化时间15 s时印制出来的棉织物的导电性、导电耐久性最佳。

Abstract:

Reduced graphene oxide (RGO) was used to print on the surface of cotton fabrics to obtain flexible conductive textile materials by UV-curing technology. The mass concentration of RGO, polyurethane acrylate (PUA), photoinitiator 1173 and trimethylolpropane triacrylate (TMPTA) and the curing time on conductive properties of cotton fabric was explored. The conductivity of cotton fabrics were tested, and the morphology of RGO printed on the surface of cotton fabrics was characterized by scanning electron microscopy. The results show that the conductivity of cotton fabrics increases with the increasing of RGO mass concentration. The electrical durability, however, decreases with the increasing of RGO mass concentration. The conductivity of cotton fabrics decreases with the increasing of PUA, photoinitiator 1173 and TMPTA mass concentration, and the electrical durability increases at the same time. The SEM test results show that with the increasing of RGO mass concentration, the amount of RGO coated on the surface of cotton fabrics is increased, and the continuity of RGO conductive layer is enhanced. It is concluded that the optimal UV curable pringting process is the mass ratio of RGO, PUA, TMPTA and photoinitiator 1173 10:4:69:17, curing for 15 s, the printed cotton fabrics obtain excellent electrical conductivity and electrical durability.
