Abstract
FTIR, FT-Raman, and X-ray diffraction techniques were used to determine chain segregations and lamellar structures of the mixed binary n-paraffins with different chain lengths. The results of three different techniques, infrared spectroscopic studies of crystal field splitting, the Raman longitudinal acoustic mode, and the SAXS long period measurements were compared one another to understand the crystallization mechanism of separated or mixed n-paraffin lamellae.

사슬길이가 서로 다른 두 종류의 n-paraffin 혼합물이 결정을 형성할 때 사슬의 움직임과 형성된 라멜라의 구조를 조사하기 위하여 FTIR, FT-Raman, XRD 실험방법을 이용하였다. FTIR crystal field splitting, Raman longitudinal acoustic mode, 그리고 SAXS long period 측정 결과들을 비교하여 사슬길이가 다른 두 n-paraffin 사슬이 혼합되어 하나의 라멜라를 형성하거나 분리되어 각각의 라멜라를 형성하는 과정을 연구하였다.
