Table 2 and Fig.3 show the influences of particle size and contents of PEG on
morphology of TiO2 film.Pore size and porosity increased with the amount of the
added PEG.The SEM images (Fig.4) also confirmed these phenomena.The shape
and size of TiO2 crystallites did not change with the addition of PEG.In addition,
Fig.5 shows that roughness factor (rf) and porosity of the film changed linearly with
the amount of PEG.While TiO2 particles in the sol were surrounded by adsorbed
PEG molecules under the low concentration conditions,in the very high
concentration conditions,excess amount of the PEG seems to exist as large
aggregates in the sol.Therefore,larger pores should be formed in the film during the
sintering process with the increase of PEG.
The roughness factor (rf) of T iO2 film decreased as the particle size of TiO2
crystallites increased.The average pore size and porosity of the film decreased with
decreasing particle size because the void between the particles became smaller with
the decrease of the particle size.The mesoporous film became more brittle when the
concentration of PEG was higher than 50 wt%:From these results,we found that
pore size,porosity and effective area of the mesoporous film could be precisely
controlled by combination of the autoclaving temperature for the sol preparation
and the amount of PEG in the paste.
