초록

We fabricated the sample of u1tra thin lipid membrane(L-${\alpha}$-DLPC ) by LB methode. The $\pi$-A isotherm of the DLPC was measured at the air-water interface varying with the compressing speed and amounts of solutions for spreading. For good property of lipid monolayer film, it was necessary for the lower speed of compressing, and 40${\mu}\ell$ of solutions for spreading. The molecular arrangement of deposited films were evaluated by measuring the absorption, transmitance and intensity with the UV spectrophotometer. The Y-type multilayers prepared at 50mN/m showed weaker than Z-type. So we found building-up of structurally high quality LB films is essential to study properties of the films and to get reproducible data.
