Abstract:
Electroactive coatings for smart wearable textiles based on a furan bio-epoxy monomer (BOMF) crosslinked with isophorone diamine (IPD) and additivated with carbon nanotubes (CNTs) are reported herein. The effect of BOMF/IPD molar ratio on the curing reaction, as well as on the properties of the crosslinked resins was first assessed, and it was found that 1.5:1 BOMF/IPD molar ratio provided higher heat of reaction, glass transition temperature, and mechanical performance. The resin was then modified with CNT to prepare electrically conductive nanocomposite films, which exhibited conductivity values increased by eight orders of magnitude upon addition of 5 phr of CNTs. The epoxy/CNT nanocomposites were finally applied as coatings onto a cotton fabric to develop electrically conductive, hydrophobic and breathable textiles. Notably, the integration of CNTs imparted efficient and reversible electrothermal behavior to the cotton fabric, showcasing its potential application in smart and comfortable wearable electronic devices.
摘要:
本文报道了基于与异佛尔酮二胺(IPD)交联并添加有碳纳米管(CNT)的呋喃生物环氧单体(BOMF)的智能可穿戴纺织品的电活性涂层。BOMF/IPD摩尔比对固化反应的影响,以及对交联树脂的性能进行了首次评估,发现1.5:1的BOMF/IPD摩尔比提供了更高的反应热,玻璃化转变温度,和机械性能。然后用CNT对树脂进行改性以制备导电纳米复合膜,在添加5phr的CNT后,电导率值增加了8个数量级。最后将环氧树脂/CNT纳米复合材料作为涂层应用到棉织物上,以形成导电,疏水性和透气纺织品。值得注意的是,碳纳米管的整合赋予棉织物有效和可逆的电热行为,展示其在智能舒适可穿戴电子设备中的潜在应用。
