“…After coating, new peaks at approximately 1260 and 797 cm –1 were observed which were attributed to the −SiCH 3 and −Si(CH 3 ) 2 from PDMS, respectively . Moreover, the stretching vibration peak of Si–O–Si (1095 cm –1 ) occurred, which further indicated the successful cross-linking of PDMS and FMTS with fiber. , The above results demonstrate the strong chemical bond formed between the coating and the bare fabric, which helps the fabric survive mechanical wear and tear during actual usage.…”

Directional water transport textiles are an energyfree approach to improving the comfort of the human body. However, existing strategies mainly focus on enhancing the capacity of directional water transport, complicating the preparation process and limiting the long-term durability of textiles. Herein, a skin-like fabric inspired by sweat glands was prepared in one step by patterning printed hydrophobic paste on the fabric. This skin-like fabric has achieved the desired one-way water transport index (R, 721%), air permeability of 104 mm s −1 , and water vapor transmission rate (298 g m −2 h −1 ). More significantly, due to the strong chemical bonds between the fabric and the coating, the skin-like fabric exhibited a high weight retention of 99.4% after 400 abrasion cycles and stable performance (R, 658%) after 25 h of washing. This work proposes a reliable way to prepare highperformance fabrics with durability, which show great potential for applications in functional textiles for personal moisture management.

“…The active species generated from helium−oxygen plasma reacted with the surface, resulting in polar groups like oxygen‐containing group and the rough surface induced the high surface energy. Therefore, the surface of PVC became hydrophilic after the treatment of plasma 34 . Furthermore, due to the presence of a large number of hydroxyl groups on the surface of SiO 2 , it exhibits excellent hydrophilicity.…”

In order to mitigate inflammation caused by the implanted device, the hydrophilic and slow‐release drug coating of PVC was prepared by the treatment of atmospheric pressure plasma jet (APPJ) and grafting porous SiO2 sphere to load the anti‐inflammatory drug ibuprofen. The structural change of the original PVC, the PVC treated by APPJ as well as the PVC‐grafted porous SiO2 coating were characterized. The results showed that SiO2 spheres were regularly arranged on the surface of the PVC treated by APPJ due to its surface grafted with numerous oxygen‐containing functional groups. The PVC‐grafted porous SiO2 sphere coating exhibited hydrophilic properties and its contact angle was only 19.83°. Meanwhile, this coating had a significant slow‐release of ibuprofen and remained equilibrium after 96 h, compared with the original PVC fully releasing IBU for 24 h. This work gives an innovative strategy for preparing the functional coating.Highlights APPJ technique presented to increase oxygen‐containing function groups on PVC. SiO2 spheres grafted and regularly arranged on the APPJ‐treated PVC surface. Mesoporous SiO2 nanoparticle coating was prepared on PVC surface. Ibuprofen loaded into the mesoporous SiO2 nanoparticle coating. The coating has the properties of hydrophilic and slow‐release of ibuprofen.
