Abstract
Mazkur tezisda gidrogellarni sintez qilishning zamonaviy usullari, ularning fizik-kimyoviy xususiyatlariga ta’sir etuvchi omillar hamda optimal sintez sharoitlarini belgilash mezonlari tahlil qilingan. Tadqiqot yo‘nalishida tabiiy polimer hisoblangan natriy karboksimetilsellyuloza (KMS-Na), sintetik polimer poliakrilamid (PAA) va bor kislotasi (H₃BO₃) ishtirokidagi polimer kompozitsiyalariga alohida e’tibor qaratilgan. Ushbu komponentlarning o‘zaro ta’siri natijasida suvni yutish, saqlash va polimer tarmog‘ining barqarorligini boshqarish imkoniyatlari ko‘rib chiqilgan.

В данной диссертационной работе анализируются современные методы синтеза гидрогелей, факторы, влияющие на их физико-химические свойства, а также критерии определения оптимальных условий синтеза. Исследование посвящено полимерным композициям на основе натрий-карбоксиметилцеллюлозы (Na-КМЦ) — природного полимера, — а также синтетического полимера полиакриламида (ПАА) и борной кислоты (H₃BO₃). В работе рассматривается, каким образом взаимодействие между этими компонентами позволяет регулировать водопоглощение, влагоудерживающую способность и стабильность полимерной сетки.

This thesis analyzes modern methods for synthesizing hydrogels, the factors influencing their physicochemical properties, and the criteria for determining optimal synthesis conditions. The research focuses on polymer compositions involving sodium carboxymethyl cellulose (Na-CMC)—a natural polymer—along with the synthetic polymer polyacrylamide (PAM) and boric acid (H₃BO₃). The study examines how the interaction between these components enables the control of water absorption, water retention, and the stability of the polymer network.
