In recent times e-textiles have emerged as wonder safeguards due to the great potential background in space, military, healthcare, or portable electronics. As a result, widespread research and development have been done to make significant advancement in this field, but it still remains a key challenge to use one single product with multifunctional attributes with the past performance of key characteristics. In this work, phase-separated PEDOT:PSS ornamented with reduced graphene oxide (rGO) nanosheets, deposited on the newly fabricated ultralightweight, superhydrophobic, and mechanically enriched merino wool/nylon (W–N) composite textile followed by the dipping and drying strategy. The open edges-layered structure of rGO helping uniform deposition of PEDOTs clusters, which allows the formation of a stacked layer of PEDOTs/rGO-PEDOTs/PEDOTs for robust three-dimensional electrical transforming channel network within the W–N textile surface. These dip-coated multifunctional textiles show high electrical conductivities up to 90.5 S cm–1 conjugated with a flexible electromagnetic interference shielding efficiency of 73.8 dB (in X-band) and in-plane thermal conductivity of 0.81 W/mK with a minimum thickness of 0.84 mm. This thin coating maintained the hydrophobicity (water contact angle of ∼150°) leading to an excellent EM protective cloth combined with real-life antenna performance under high mechanical or chemical tolerance. Interestingly, this multiuse textile can also act as an exceptional TASER Proof Textile (TPT) due to a short out of the electrical shock coming from the TASER by its unique conducting network architecture. Remarkably, this coated textile can get a response by the soft touch to lighten up the household bulb and could establish wireless communication via an HC-05 Bluetooth module as a textile-based touch switch. This developed fabric could perform as a new potentially scalable single product in intelligent smart garments, portable next-generation electronics, and the growing threat of EM pollution.

源自美利奴羊毛/尼龙聚合物纳米复合材料的多功能智能纺织品,用作下一代微波吸收器和软触摸传感器

近年来,由于太空,军事,医疗保健或便携式电子领域的巨大潜力,电子纺织品已成为一种奇妙的保护措施。结果,已经进行了广泛的研究和开发以在该领域取得重大进展,但是使用具有多功能特性的单个产品并具有过去的关键特性仍然是一个关键的挑战。在这项工作中,用还原的氧化石墨烯(rGO)纳米片装饰的相分离的PEDOT:PSS,沉积在新制造的超轻,超疏水和机械浓缩的美利奴羊毛/尼龙(W–N)复合纺织品上,然后采用浸渍和干燥策略。rGO的开放边缘层结构有助于PEDOT簇的均匀沉积,这允许在W–N纺织品表面内形成用于鲁棒三维电气转换通道网络的PEDOT / rGO-PEDOT / PEDOT的堆叠层。这些浸涂多功能纺织品显示高达90.5 S cm的高电导率–1加上灵活的电磁干扰屏蔽效率(X波段为73.8 dB)和面内导热率为0.81 W / mK(最小厚度为0.84 mm)。这种薄涂层保持了疏水性(与水的接触角约为150°),从而获得了出色的EM保护布,并在高机械或化学耐受性的情况下具有真实的天线性能。有趣的是,由于TASER独特的导电网络架构可避免因电击而产生的电击,因此这种多用途纺织品还可以用作出色的TASER耐火纺织品(TPT)。值得注意的是,这种涂层的纺织品可以通过轻柔的触摸得到响应,从而减轻家用灯泡的负担,并且可以通过HC-05蓝牙模块作为基于纺织品的触摸开关来建立无线通信。
