LLDPE와 나노탄산칼슘으로 구성된 나노컴포지트의 결정화 거동 및 물성에 관한 연구
A Study on the Crystallization Behavior and Physical Property in LLDPE/CaCO3 Nanocomposite
Noncomposite of LLDPE (linear low density polyethylene) with different contents of inorganic nano CaCO3 particles were prepared. The behavior of nano CaCO3 crystals was investigated. It was shown that nano CaCO3 has typical hexagonal structure. And also it has vaterite and calcite crystal. Through X-ray diffraction (XRD) measurements and UTM (Universal Testing Machine) test, it was found that as the contents of nano CaCO3 particles in noncomposite increase, the crystallization also increase, whereas the elongation property decrease.
