“…The electrical conductivity of natural fibers can be controlled in part by the doping process. The degree to which additives alter the resistance of polymers depends on their chemical makeup, how they interact with the macromolecular matrix, and the kind of physical flaws in natural fibers [3,[5][6][7].…”

The main objective of the research was to identify the semiconducting characteristics of mature medium-thick (diameter 14, 15 µm) "Xorazm-150" cotton fibers both undoped and doped with 1.5% aqueous solution of KMnO4, including current versus voltage and temperature dependence, temperature dependence of electrical conductivity, the influence of doping time on conductivity, and photoconductivity. The research was conducted in the temperature range (296-360 K) and the voltage range (0-100 V). The infrared spectra of the undoped and KMnO4-doped samples were studied (Both samples were mercilized with NaOH). It was found that the cotton fibers sample doped with KMnO4 had considerably higher electrical conductivity than the undoped sample. It was determined that the cotton fibers sample doped with KMnO4 obeys the law of Ohm when current flows through it. Also, it was analyzed that the formation of photoconductivity of the cotton fibers sample doped with KMnO4 under the influence of ultraviolet radiation indicates that the photoconductivity is mainly related to the formation of band electron-hole pairs. The deep surface created by doping cotton fibers with a 1.5% solution of KMnO4 in water was found to have an activation energy that was determined from the results.

“…When treating the surface of CF, it was revealed that the properties are mainly determined by grade and cuticle of the surface part of CF with a thickness of the order of 1 μm with a conditional fiber diameter of 10-15 μm [5]. Photoluminescence [6] and photoconductivity (PC) in the intrinsic absorption region of CFs doped with iodine were also found in CF [7]. Also, infrared quenching and long-term relaxation of photoconductivity in due to the adherence of charge carriers to the deep levels formed upon the introduction of iodine into an CF were found [8][9][10].…”

It was revealed that the photoconductivity spectra of various varieties of cotton fibers doped with iodine are different from each other. It was found that the electrical conductivity of cotton fibers undoped and doped with iodine and KMnO4 increases exponentially with increasing temperature. Infrared quenching and long-term relaxation of the photoconductivity of cotton fibers doped with iodine were detected. For the first time, it was found that with small doses of UV irradiation of silkworm gren, the quality of silk fibers improves, and with large doses it worsens
