The results show that the perfect Honeycomb pattern films without defects within area of 0.8cm^2 can be obtained at the PS concentration ranges from 20 mg/mL to 50 mg/mL and PS/TEOS mass ratio less than 2. The films cast from the chloroform solution of dicarboxyl terminated PS were more perfect than those cast from the chloroform solution of monocarboxyl terminated PS. The perfect Honeycomb structure films could be obtained with both chloroform and benzene as solvents, but the pore diameter of films cast from benzene solution of PS was larger than that of films cast from chloroform solution of PS.
