제목 규칙적인 2차원 배열 제조를 위한 Silica 나노입자의 LB 필름 형성 특성
초록 The 2D ordered array of silica nanoparticles can be fabricated using Langmuir-Blodgett (LB) technique.As a preliminary step, we conducted a study on the characteristics of LB film formation of monodisperse silica nanoparticles. Hydrophilic monodisperse silica nanoparticles were prepared by the sol-gel based Stber method and their surfaces were modified to be hydrophobic. The surface pressure (π)-area (A) isotherms of spread monolayers of those silica nanoparticles at the air/water interface were investigated as functions of the compression/expansion and the pH values of subpahse. The results are discussed in terms of the surface charge of nanoparticles and interparticular interactions.
