摘要: Abstract Viscoelastic characterization of titania-based sol–gel materials are investigated. Small amplitude oscillatory measurements used to determine the gelation time t g and critical exponent frequency dependence loss storage moduli. The scaling is analyzed in order estimate a fractal dimension at . Hydrolysis molar ratio, titanium concentration temperature parameters have an effect on but not structure gel (gel time). However acetylacetone as inhibitor control reactivity seems modify both kinetic process structure.
