Layer-by-layer(LbL) assembly technique is one of the environment-friendly and versatile way of preparing the hydrophobic surface. The hydrophobic surface was prepared by coating porous LbL assembled surface using fluorinated silane. Porous films were prepared by post acid treatment of poly(allylamine hydrochloride)(PAH)/poly(acrylic acid)(PAA) LbL film. Different pore structures have been reported depending on the molecular weight of PAH. Here, we utilized PAH mixture of two average molecular weight to fine-tune the porous structure. Surface morphologies, roughness, and pore volume werer dependent on the PAH mixing ratio and acid treatment condition. Accordingly, we could successfuly control the hydrophobicity of LbL film by coating the LbL films of varioius pore structure with fluorinated silane |
