We present here, the effect of surfactant concentration, different solvents and particle sizes on isotherm of silica nanoparticles at air/water interface. The experiments were performed by Langmuir–Blodgett (LB) technique and pressure ∏–A isotherms were recorded. Silica nanoparticles (NPs) of different sizes namely; 30 nm, 150 nm and 630 nm, were synthesized by Stöber's method and characterized by using scanning electron microscopy to determine their sizes and dispersity. As-synthesized NPs were hydrophobized to varying extents through addition of varying amounts, ranging from 0.5 mg to 1.5 mg, of the cationic surfactant,cetyltrimethylammoniumbromide (CTAB). Effect on lift off area (area/particle) and corresponding yield were investigated and reported. This parametric study can adds on in meeting the requirement of reproducibility of LB films.
