Effect of Boron Compound Addition in Flame Deposition of Functional Films

AbstractSuperhydrophobic SiO2 films have been prepared by a flame deposition method. The influence of boron compound as additive on the morphology, structure and property has been studied with SEM and quantitative nanomechanical property mapping (QNM, Bruker). SEM photographs show that the size of nanoparticles in the deposited film has increased due to the addition of boron compound. The deposit rate also improves as the concentration of the boron compound increases. Boron compound has effectively promoted the precursor reaction in the gas phase. As is shown by QNM characterization, under all selected concentrations of boron additive, boron compound improves the fusion between the flame made nanoparticles and the substrate, achieving higher binding capacity. The superhydrophobic property of deposited films has been affected by the changed morphology and structure caused by boron additive. The proportion of nano-scale structure on the surface has decreased, leading to a constant contact angle but greatly decreased rolling angle. The mechanism has been preliminarily explored based on the special property of boron and flame reaction process. Surface growth and low temperature diffusion contribute to the enhancement of film binding force.
