Paper Abstract

Mesoporous silica thin films with the three-dimensional (3D) pore structure and regular channels have been prepared by dip- or spin-coating on substrates with using a triblock copolymer surfactant (F127) as a template. This paper studied the influences of the various conditions on some characteristics of films with the oriented pore by DTA (different thermal analysis), FTIR (Fourier-transform infrared), small- or wide-angle X-ray diffraction (SA-or WA-XRD) and high-resolution transmission electron microscopy (HRTEM)etc. The adsorption and desorption for N2(BET method) show that the film's specific surface area is about more 650m2/g and the pore channels size is about 3- 7 nm. This work also reported the influence of the array pore structure assembled with ferric group on magnetization process and showed that the coercive force and specific saturation magnetization of composite occurred in different performance as compared with the conventional magnetic materials.
