입체규칙성 PMMA 단일층의 이전 특성에 대한 이전압력, 기판의 종류 그리고 입체규칙성의 영향을 평균이전비를 통하여 체계적으로 살펴 보았다. 이전 특성과 함계 단일층의 표면압력-면적 그리고 표면전위-면적 등온선을 측정하였다. Atactic과syndiotactic PMMA의 경우 1mNm^-1 그리고 isotactic PMMA의 경우 5mNm^-1이하의 이전압력에서 Z-형 Langmuir-Blodgett(LB)막이 형성되었다. 이전압력이 이러한 압력보다 커짐에 따라 기판을 담글 때의 평균 이전비는 증가하여 atactic과syndiotactic PMMA는 10mNM^-1그리고 isotactic PMMA는 15mNM^-1에서 각각 Y-형 LB막으로 이전되었다. 이전된 첫 번째 층을 열처리한 경우 이전 특성은 유리 기판을 제외하고는 기판 종류에 따라 큰 차이가 없었다. 본 연구에서는 단일층의 겉보기 쌍극자 모멘트로부터 유추된 단일층의 분자 배열과 조밀도에 기초하여 단일층과 물 그리고 이전된 막과 단일층의 결합력을 비교함으로서 입체규칙성 PMMA 단일층이 이전 특성이 해석될 수 있음을 보였다.

The effects of the transfer pressure, types of the substrates and stereoregularity on the transfer characteristics of monolayers of stereoregular PMMAs were systematically investigated in terms of the average transfer ratio. Along with the transfer characteristics, surface pressure-area and surface potential-area isotherms of the monolayers were measured. Z-type multilayers were formed at a transfer pressure below 1 mNm^-1 for the atactic and syndiotactic PMMA and below 5mNm^-1 for the isotactic PMMA, respectively. The average transfer ratio of the downward stroke increased as the transfer pressure increased from the above values, forming Y-type multilayers at the transfer pressure of 10mNm^-1 for the atactic PMMA and syndiotactic PMMAs and at 15mNm^-1for the isotactic PMMA, respectively. The effect of the types of the substrate on the transfer characteristics was not significant except for the glass substrate when the transferred first layers were baked. The molecular arrangement of the floating monolayers deduced from the apparent dipole moment was found to be informative in interpreting the transfer characteristics of the monolayers of stereo -regular PMMAs.
