“…Chen et al (11) reported that the growth rate of particles in competitive growth experiments in which new particles are formed do not conform with predictions by the reaction-limited mechanism. They suggested that this discrepancy resulted from the growth controlled by the diffusion of subparticles (11).…”

“…The mechanism of Stöber method with respects to silica particle formation, growth, and particle size, distribution, and shape have been investigated in the past decades [30][31][32][33][34][35][36][37][38][39][40][41][42]. However, the mechanisms reported by different researchers are contradictory.…”

The formation of SiO 2 nanoparticles with uniform particle size is accomplished through direct hydrolysis of tetraethyl orthosilicate (TEOS), while the deposition of the formed SiO 2 on PP separators was conducted in the same solution containing polyvinylidene fluoridehexafluoropropylene (PVDF-HFP) as binders and acetone as the solvent. The effects of the ceramic coating on the surface morphology, tensile strength, contact angles, electrolyte uptake, thermal shrinkage of the PP separators and the cell performances such as battery rate capability and Coulombic efficiency were investigated. The coated separators show significant reduction in thermal shrinkage and improvement in tensile strength, contact angles, electrolyte uptake and battery performance as compared to the plain PP separator.

“…Polymerization occurred in multidimensional directions, which formed short-chain cross-linked structures, then short-chains polymerized inner with increasing ammonia concentration, and fi nally formed spherical particles [20][21][22] . With increasing ammonia concentration, the diameters of particles would enlarge as well.…”

Super-hydrophobic surfaces with water contact angle (WCA) higher than 150° generated a lot of interests both in academic and in industry because of their self-cleaning functionality. Emphasis was given to the effect of pH value on the hydrophobic behavior of the obtained fi lms or powders. At fi rst, SiO 2 sols were prepared by diluted ammonia. We found that following the increase of pH value of sol from 8 to 9, WCAs of the obtained fi lms increased from 121.8° to 131.8°. Following the continued increase of the pH value of sol, precipitates began to appear and smooth fi lm could not be obtained. The WCAs of the obtained powders could reach 121.7°, and through modifying by TMCS could further increase to as high as 165° and the water sliding angle (WSA) was 2°. The results of SEM indicate that the hydrophobic properties of the powders without modifying by TMCS should be originated from the formation of nano/micron binary structure, i e, a micronscale diameter and a nano-scale surface roughness. In this work we provide a better solution to fabricate superhydrophobic silica coating surface with a simple method at low cost.
