Mazkur tadqiqotda sof polivinilxlorid (PVX), karbamid bilan modifikatsiyalangan PVX (PPE-2) hamda CuO va Fe3O4 nanobirikmalari asosida tayyorlangan funksional nanokompozitlarning termik parchalanish xususiyatlari taqqoslab o‘rganildi. Termogravimetrik tahlil (TGA) va differensial skanerlash kalorimetriyasi (DSC) yordamida massa yo‘qotilishi, degradatsiya bosqichlari va termik barqarorlik baholandi. Natijalar shuni ko‘rsatdiki, PVXning karbamid bilan modifikatsiyasi uning issiqlikka chidamliligini oshiradi, metall oksid nanobirikmalari qo‘shilishi esa barqarorlikni yanada kuchaytirib, parchalanish mexanizmini o‘zgartiradi. Olingan natijalar CuO va Fe3O4 nanobirikmalarining stabilizatorlik rolini tasdiqlaydi va bunday materiallarning yuqori issiqlik va kimyoviy barqarorlik talab etiladigan sohalarda qo‘llanish imkoniyatlarini ko‘rsatadi.
