Ink printing can be considered a desirable production method for mass manufacturing inexpensive electronic textiles. Copper nanowires (CuNWs) have attracted enormous attention due to preponderant electric conductivity, mechanical properties, and large abundance in recent years. Unfortunately, low dispersibility, poor binding, incompatibility of CuNWs greatly limit their development conductive inks. Herein, green CuNW ink with high conductivity durability was reported, which couples tannic-polyethylenimine (TA-PEI) modified (TA-PEI@CuNW) heterostructure as "brick" carboxymethyl cellulose (CMC) acting "mortar" inspired by the "brick–mortar" structure pearls. The exhibits splendid adhesion strength on textiles, attributed abundant hydrogen bonding sites between CMC TA-PEI@CuNWs. obtained printed fabric also shows superb (sheet resistance Ra = 3.33 Ω·sq–1) bending (withstanding 1500 cycles). Furthermore, presented exceptional application potential Joule heating (112.8 °C at 1.5 V voltage) electromagnetic shielding (shielding efficiency SET 50.488 dB). We think that may provide insight into personal thermal management fabrics.

Abstract The design of electrically conductive textiles appears to be a promising approach combat the existing challenge deaths caused by severe cold climates around globe. However, reports on scalable fabrication tolerant maintaining low electrical resistance with an ability for unperturbed and prolonged performance are scarce. Here, breathable wrappable water‐repellent textile (water‐repellent CT) electrothermal photothermal conversion abilities at external voltage in weak solar light is introduced, respectively. In current approach, less carbon‐containing silver nanowires (AgNWs) selected spray deposit commercially available woven attend uniform highly network over large dimension. subsequent deposition reaction mixture small molecules prevents aerial oxidation deposited AgNWs even elevated temperatures provides bioinspired extreme water‐repellence. Thus, it maintains when exposed different aqueous environment. Using scalability durability prepared CT, relevant wearable devices derived demonstrate personal heat management rechargeable portable battery duration severely conditions. CT enabled energy‐efficient “wrappable” heating, providing basis various potential applications.
