摘要

当将电子产品印刷到纺织品上时,通常使用热塑性聚氨酯(TPU)层,不幸的是,它会干扰纺织品的许多理想性能。为了尽量减少TPU的这种影响,研究了不同TPU类型和层压条件对电子纺织品性能的影响。研究发现,为了获得最佳导电性,TPU薄膜厚度应在~ 100µm,但应避免使用较厚的薄膜,因为它们会增加刚度并降低透气性。较低密度(较少结晶)的TPU被认为是可取的。有一些层压参数的权衡,更高的温度和更长的时间增加刚度,但提高印刷油墨的导电性;然而,在任何一种情况下,较低的层压都是可取的。

Mitigating the Impact of Thermoplastic Polyurethane Films on the Performance of Electronic Textiles
When printing electronics onto textiles, a thermoplastic polyurethane (TPU) layer is typically used, which unfortunately interferes with many desirable properties of textiles. To minimize this impact of the TPU, the effect of different TPU types and lamination conditions on the electronic textile properties are investigated. It is found that for optimal conductivity, the TPU film thickness should be ~ 100 µm, but thicker films should be avoided as they increase stiffness and worsen breathability. Less dense (less crystalline) TPU is found to be preferable. There is trade-off with some lamination parameters, with higher temperatures and longer times increasing stiffness but improving printed ink conductivity; however, a lower lamination pressure is preferable in either case.
