Creating a smart textile via the self‐assembly of responsive polymer particles on poly(ethylene terephthalate) fibers

Abstract

A novel method is presented for the construction of a hierarchical microstructure/nanostructure via the chemical self‐assembly of poly(N‐isopropyl acrylamide‐co‐acrylic acid) particles on polyester fibers. The textile of the particle‐bound fibers possessed smart wettability and an oil‐absorbing capacity. The wettability was dependent on the initial contact angle and spreading time of water droplets on the particle‐bound textile, which could be controlled with the content of acrylic acid inserted into the polymer chains. The wettability of the particle‐bound textile was responsive to the pH value. In addition, the textile was superoleophilic on an air–solid surface and could absorb oil quickly from water. The oil‐absorbing capacity could be controlled by the alteration of the pH value. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46834.

A Conductive Bamboo Fabric with Controllable Resistance for Tailoring Wearable Sensors

“…19 Here, a coarse conductive surface could be created on the fibers of the bamboo fabric by binding P(NIPAM-AA) and then conductive PANI, as shown in Figure 1a. Similar to the self-assembly of P(NIPAM-AA) particles on polyester fibers, 24 the bamboo fabric was treated with γ-aminopropyl triethoxysilane for obtaining the amine group on the fiber surface, which was proven with the new peak at 399.64 eV in the XPS spectrum (Figure S2). Then, the self-assembly of P(NIPAM-AA) particles on bamboo fibers is realized through the reaction between the amine group on the fiber surface and the carboxyl group in P(NIPAM-AA) particles with the help of 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS).…”

“…Electrically conductive materials are commonly practiced in architecting wearable textile sensors, supercapacitor, actuator, antenna, data transfer, monitoring, and so on, following different fabrication processes. [34][35][36][37][38][39] Fiber or yarn is considered as the fundamental building block and the basic visible unit of textile architecture to construct a different stylistic pattern of wearable clothing. Conductive materials such as metallic wires, polymer, carbon-based substances are normally incorporated with polymeric yarn surface following spinning (melt or wet) process.…”
