Annotatsiya : Mazkur maqolada elektrospinning texnologiyasi asosida mahalliy tabiiy va sintetik polimerlardan nanotolali noto‘qima materiallar olish bo‘yicha olib borilgan tadqiqot natijalari yoritilgan. Xususan, xitozan, sellyuloza, ipak fibroini, poliamid kabi polimerlarning eritmalari asosida shakllantirilgan nanotolalarning fizik-kimyoviy xossalari va ularning tibbiyot, ekologiya va elektrotexnika sohalaridagi amaliy qo‘llanilish imkoniyatlari ko‘rib chiqilgan. Shu bilan birga, Surxondaryo viloyatida yaratilgan “Termiz-202” va “Termiz-208” ingichka tolali g‘o‘za navlari asosida olingan tolalarning struktura va xossalarini o‘rganish orqali nanotexnologiyalarga mos polimer manbalarini aniqlashga urinish qilingan. Tadqiqotlarda polimerlarning molekulyar-massaviy tarkibini baholashda gidrodinamik va polyarizatsion-optik metodlardan foydalanilgan. Olingan natijalar yuqori samarali nanofiltrlar, dorivor vosita tashuvchilar va ion almashinish materiallari yaratishda katta amaliy ahamiyatga ega ekanligini ko‘rsatdi.
Annotatsion : This article presents the results of research on the production of nanofibrous nonwoven materials based on local natural and synthetic polymers using the electrospinning technology. In particular, nanofibers formed from solutions of polymers such as chitosan, cellulose, silk fibroin, and polyamide were studied in terms of their physicochemical properties and practical applications in medicine, environmental protection, and electrical engineering. Additionally, efforts were made to identify suitable polymer sources for nanotechnology applications by studying the structure and properties of fibers derived from fine-fiber cotton varieties “Termiz-202” and “Termiz-208” developed in the Surkhandarya region. Hydrodynamic and polarization-optical methods were used to assess the molecular weight distribution of the polymers. The findings demonstrate the high potential of these nanofibrous materials for use in high-efficiency nanofilters, drug delivery systems, and ion exchange materials.
