Liquid repellency treatment has many applications in various sectors including self-cleaning surfaces. In recent research, It was confirmed that fluoride group on a surface had hydrophobic and oleophobic properties. Polysilsesquioxanes(PSSQs) were prepared by hydrolysis and condensation polymerization using various tri-functional alkoxide silane having a T3 structure. In this study, Trifluoropropyltrimethoxysilane was used as a precursor, Fluorine functionalized PSSQs(F-PSSQs)of ladder structure were prepared by controlling silane concentration and pH at the solution. F-PSSQs were analyzed by 29Si-NMR to observe the T2 and T3 peaks. The crystal lattice of products was confirmed by XRD analysis and a molecular weight of F-PSSQs was compared with the molecular weight of predicted structure by MALDI-TOF.
