RESUMEN
The development of cotton fabrics with special properties such as superhydrophobicity, self-cleaning, oil/water separation, anti-bacterial activity and blood repellency without compromising its intrinsic properties such as flexibility, breathability, comfort, and biodegradability is quite challenging task. In this study, a simple and environmentally friendly approach was used to fabricate superhydrophobic cotton fabric by introducing chitosan-based composite coatings over cotton fabric. The surface properties of the cotton samples were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and Fourier-transform infrared spectroscopy. The prepared cotton fabrics showed excellent superhydrophobicity with a water contact angle of 154.4° and also possess excellent antibacterial activity against Gram positive and negative bacteria with inhibition zone of 16 mm and 22 mm in disk diffusion method and shake flask method results revealed that the chitosan-PAni-ZnO-STA coated cotton effectively inhibits the bacterial growth. Furthermore, the self-cleaning, blood repellency and oil-water separation performance of cotton fabric were also performed to examine the feasibility of as-modified cotton in both environmental and clinical applications.
RESUMEN
In this review, the current state of research on textile-based temperature sensors is explored by focusing on their potential use in various applications. The textile-based sensors show various advantages including flexibility, conformability and seamlessness for the wearer. Integration of the textile-based sensors into clothes or fabric-based products enables continuous and sensitive monitoring of change in temperature, which can be used for various medical and fitness applications. However, there are lacks of comprehensive review on the textile-based temperature sensors. This review introduces various types of textile-based temperature sensors, including resistive, thermoelectric and fibre-optical sensors. In addition, the challenges that need to be addressed to fully realise their potential, which include improving sensitivity and accuracy, integrating wireless communication capabilities, and developing low-cost fabrication techniques. The technological advances in textile-based temperature sensors to overcome the limitations will revolutionize wearable devices requiring function of temperature monitoring.
