초록

여러 형태의 탄산칼슘을 합성하였다. 이렇게 합성된 여러형태의 탄산칼슘을 혼합기에 넣어 PP와 혼합하여 PP/CaCO₃ 복합재료를 제조하였다. 제조된 복합재료를 입자의 형태에 따른 결정화온도, 용융열, 구정의 크기 그리고 기계적성질에 미치는 영향을 조사한 결과 입자의 형태가 결정화온도와 용융열 그리고 구정의 크피에 많은 영향이 있음을 알 수 있었다. 특히, vaterite를 혼합하였을 경우 다른 입자에 비하여 구정의 크기는 적었으나 결정화도는 증가하였으며, 이로 인해 인장강도와 영율은 다른 입자에 비하여 높은 값을 나타내었다.

The various shape of calcium carbonate were prepared. For the preparation of the PP/CaCO₃ composite, these synthetic calcium carbonate(cubic, spheric and neddle type) and PP were mixed on a two roll mill and the mixture were pressed into plate. The effect of particle shape in the prepared composite on the crystallization temperature, heat of fusion, size of spherulite and mechanical properities were investigated. It was found that the former four were strongly influenced by that. When, especially, vaterite was mixed with PP, the size of spherulite was smaller and the degree of crystallinity was higher than others. Therefore, the tensile strength and Young's modulus were higher.
