“…In the current study, thymol, γ‐terpinene and p‐cymene are major compounds and show their antibacterial activities by the mentioned mechanisms. The presence of HY‐Silane could increase antibacterial activities that is in agreement with previous studies [17,47] . Loading silane increases hydrophobic interactions by the aliphatic chain of GPTMS.…”

“…The presence of HY-Silane could increase antibacterial activities that is in agreement with previous studies. [17,47] Loading silane increases hydrophobic interactions by the aliphatic chain of GPTMS. An increase in crosslinking density by siloxane bonds produced in the hydrogel network increases the porosity of binding sites and contributes to slow release.…”

Infectious wounds commonly occur and must be rapidly treated with safe and efficient agents. Antibiotic‐resistant is a major challenge for the treatment of infected wounds. This preliminary study aimed to evaluate the effects of the topical cryogel application of carboxymethylcellulose/silane‐modified hyaluronic acid (CMC/HY‐Silane) containing Trachyspermum copticum essential oil nanoemulsions (TSP NEs) for the treatment of infected wounds. Four related factors of 3‐glycidyloxypropyl‐trimethoxysilane (GPTMS), time, pH and temperature were selected and their effects were evaluated to monitor the porosity each factor with the help of Taguchi method. The maximum porosity of cryogels (39.20 %) was obtained at GPTMS=30 μL, pH=9, temperature of 25 °C and time of 30 min. CMC/HY‐Silane hydrogels containing 0.00 %, 2.00 % and 4.00 % TSP NEs were produced. Antibacterial and toxicity of the nanostructures and wound contraction, total bacterial count, histopathological parameters and the expressions of IL‐10, TGF‐β1 and NF‐κB were also assessed. The efficiency of cryogels was compared with antibiotics. In vivo and in vitro studies confirmed that the administration of cryogels containing TSPNEs accelerated the wound healing process by increasing the expressions of collagen, IL‐10 and TGF‐β, fibroblast, epithelization and decreasing edema and the expression of NF‐κB. The results also showed that cryogels could compete with synthetic ointment of mupirocin.

This article reviews conductive fabrics made with the conductive polymer poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), their fabrication techniques, and their applications. PEDOT:PSS has attracted interest in smart textile technology due to its relatively high electrical conductivity, water dispersibility, ease of manufacturing, environmental stability, and commercial availability. Several methods apply PEDOT:PSS to textiles. They include polymerization of the monomer, coating, dyeing, and printing methods. In addition, several studies have shown the conductivity of fabrics with the addition of PEDOT:PSS. The electrical properties of conductive textiles with a certain sheet resistance can be reduced by several orders of magnitude using PEDOT:PSS and polar solvents as secondary dopants. In addition, several studies have shown that the flexibility and durability of textiles coated with PEDOT:PSS can be improved by creating a composite with other polymers, such as polyurethane, which has high flexibility and extensibility. This improvement is due to the stronger bonding of PEDOT:PSS to the fabrics. Sensors, actuators, antennas, interconnectors, energy harvesting, and storage devices have been developed with PEDOT:PSS-based conductive fabrics.

“…Wang et al deposited silver/reduced graphene oxide composite onto polyester fabric, the resistance of the fabric increased to 1.9 Ω from 1.6 Ω after washing 10 cycles or bending 100 cycles. In our previous study, the washability of conductive fabric can be improved by pretreated cellulose fabric with silane coupling agents with thiol groups , due to the feasibility of reaction between silane and hydrophilic cotton with plenty of hydroxyl groups. The applicability of this method to hydrophobic synthetic fibers, especially for the widely used polyester fabrics, is still need to be further clarified.…”

Textile electrodes for electrocardiogram (ECG) acquisition should be highly surface conductive and resistant to deterioration during the use of smart clothes in washing, stretching, and bending. In order to obtain conductive fabrics with great potential for practical application in ECG acquisition, thiol groups grafted polyester fabrics were coated with a condensed silver layer via electroless plating, where the electrical resistance was as low as 7.18 mΩ/sq. The stability of the conductive coating on the fabric in application was studied in the process of elongation, bending, oxidation, and washing. Polyester fiber has a high elasticity, the silver layer presented fracture trend after elongation, and the electrical resistance reached 14.74 mΩ/sq after 20% elongation. The conductivity of the fabric was less affected by bending, and silver layer fell off a little after 3000 bending cycles. After being placed in a constant temperature and humidity environment, the electrical resistance was almost unchanged after 9 weeks. The surface square resistance of the fabric is 0.93 Ω/sq after 200 washing cycles because of the high adhesion of silver layer to the thiol groups modified fabrics. The textile electrodes were embedded in smart garment to capture the ECG signals of a human in running states. The ECG waveform was still clear after 200 washing cycles and the measured heart rate increased with the increase of movement speed. The excellent performance of as-prepared conductive fabrics shows the feasibility as textile electrodes in ECG acquisition for practical application.
