Designing of semiconductive cotton fabrics based on poly (propynyl benzo thiazolone) with UV protection and antibacterial properties

Our research aimed to prepare semiconductive textile with multifunction activity such as hydrophobicity, antibacterial, and UV protection. Herein, propynyl benzo thiazolone (TH) and its polymer (PTH) were as-synthesized and investigated by FT-IR analysis. Further, the cotton fabrics were grafted in situ with each poly (propynyl benzo thiazolone) and with the as-synthesized hydrogel based on gelatin/PTH (PTH-G-T). The PTH-T and PTH-G-T were investigated by (FT-IR), (SEM), UV protection (UPF), and contact angle, and further, their electrical properties were studied by impedance spectroscopy, and dc conductivity of PTH, PTH-T, and PTH-T-G obtained at low frequency exhibited good conductivity upto 10^-4 S cm⁻¹, 4.5x10^-8 and 1.7x10^-7 S cm⁻¹, respectively. An equivalent circuit model was used to investigate the impedance spectra of PTH-T and PTH-G-T samples. The impedance could be split into two components. One component was identified as an inhomogeneity contribution, while the other was recognized as an intrinsic conduction component that exhibited characteristic semiconductor behavior. Various conduction experiments and theories are used to explain the results. Besides, they have good antibacterial and excellent UV protection. The outcomes assured the ability usage of the treated cotton fabrics in health monitoring apparel.
