Abstract
Ushbu tadqiqotda sintez qilingan kompozitning tarkibiy va termik xususiyatlari Furye-transformatsion infraqizil (FTIR) spektroskopiya hamda birgalikdagi termogravimetrik/differensial termik tahlil (TG/DTA) usullari yordamida tadqiq qilindi. FTIR spektrida N–H va O–H valent tebranishlari, aromatik halqaning skelet tebranishlari, C– N tebranishlari hamda Si–O–Si/Si–O valent tebranishlariga xos yutilish sohalari aniqlandi. 1541–1500 cm⁻¹ diapazondagi yutilishlar asosan organik modifikator tarkibidagi aromatik halqa tebranishlari bilan, 1174–1029 cm⁻¹ diapazondagi intensiv yutilishlar esa qum va kuldan kelib chiqqan silikat komponentlari bilan bog‘landi. TG/DTA natijalari kompozitning ko‘p bosqichli termik xususiyatga ega ekanligini ko‘rsatdi. Taxminan 122.38 °C da kuzatilgan termik effekt elementar oltingugurtning erishi bilan bog‘landi. Asosiy massa yo‘qotilishi taxminan 200–321 °C oralig‘ida sodir bo‘lib, massa yo‘qotilishi 8.752 mg (33.954%) ni tashkil etdi va DTA egri chizig‘ining maksimumi 304.38 °C da kuzatildi. Ushbu bosqich asosan organik modifikator va kompozit tarkibidagi boshqa termik jihatdan beqaror komponentlarning parchalanishi bilan izohlandi. 321 °C dan yuqori haroratlarda 800 °C gacha massa kamayishining bosqichma-bosqich davom etishi qoldiq organik va oltingugurt saqlovchi komponentlarning parchalanishini ko‘rsatdi.References
