Abstract
Ushbu tadqiqot ishida mis ftalosianin pigmenti bilan modifikatsiyalangan polietilen kompozitining IQ-spektr tahlili o‘rganildi. Spektrda polietilenga xos C-H va CH₂ tebranishlari bilan birga, mis ftalosianin pigmentiga tegishli C=N, C-N hamda aromatik halqa tebranishlari kuzatildi. Olingan natijalar pigmentning polietilen matritsasida mavjudligini va kompozit tarkibida strukturaviy o‘zaro ta’sir yuzaga kelganini tasdiqlaydi. Mis ftalosianin pigmenti qo‘shilgan polietilen kompozitining termik barqarorligi TGA usuli yordamida o’rganildi. Olingan tahlil natijalariga ko‘ra dastlabki bosqichda massa yo‘qotilishi juda kam bo‘lib, asosiy parchalanish yuqori harorat sohasida sodir bo‘ldi. Bu holat CuPc pigmentining polietilen matritsasida termobarqarorlashtiruvchi ta’sir ko‘rsatishini tasdiqlaydi.References
