%0 Journal Article %T Fabrication of Ordered Macroporous Titania Film using Self-assembly an Organic Template and A Simple Dip-Coating Technique %A Asep BN Nandiyanto %A Mikrajuddin Abdullah %A Ferry Iskandar %A Kikuo Okuyama %J Jurnal Nanosains & Nanoteknologi %D 2009 %I %X An organic colloidal crystal templating method has been used to fabricate an excellent and a large-are three-dimensionally ordered macroporous titania films. The matrix was obtained through a dip-coating process, with subsequent removal of the templates by heat treatment. A scanning electron micrograph confirms the ordering of macroporous structure film could be produced and transmission spectra shows a pronounced attenuation refractive index when pores was existed. Bragg¡¯s law calculation was also used to calculate the filling fraction of the titania backbone. %U http://ijp.fi.itb.ac.id/index.php/nano/article/view/239/237
