TEOS/PDMS-OH hybrid material for the consolidation of damaged pottery
The use of organic–inorganic hybrid compounds containing tetraethoxysilane (TEOS) and hydroxyl-terminated polydimethylsiloxane (PDMS-OH) is one of the most promising approaches for using alkoxysilane-based formulations to improve the effectiveness of the consolidation of traditional silicate artifacts, such as ancient stone. Based on analysis of existing damaged potteries influenced by the crys...
متن کاملSpatial patterns formed by growing TEOS polymers
2014 Silicon tetraethoxyde (TEOS) monomers are dissolved in a water/ethanol mixture. Through hydrolysis and condensation they aggregate to form branched siloxane polymers ; in a few hours these polymers build a gel throughout the solution. The patterns formed by the growing polymers are studied through small angle neutron scattering. In the reaction bath, these patterns result from repulsive in...
متن کاملComparison of Deposition Models for a TEOS CVD Process
This paper focuses on the comparison of calibrated models for teos deposition in a cvd process according to sem images of SiO2 layers. We describe the applied models and the parameters which lead to the best results for each model. The simulations have been performed using our topography simulator elsa (Enhanced Level Set Applications) which follows the surface evolution by solving the level se...
