The experimental results indicate that the interparticle repulsions and particle - water interactions can be enhanced without decreasing the particle hydrophobicity by adding SA and methanol ; thus , particulate monolayers with large hexagonally close - packed domains composed of small silica particles can be successfully fabricated using LB technique .
