stable acrylate triethoxyvinylsilane vtes core shell emulsion with Low Surface Tension made by modified micro emulsion polymerization effect of different mass ratio of mma ba in the core and shell
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2013Co-Authors: Yunfei Zhang, Rui Zhang, Chaolong Yang, Jian ZhengAbstract:Abstract Stable acrylate/triethoxyvinylsilane (VTES) core–shell emulsion with different mass ratio of MMA/BA in the core and shell was prepared via a modified micro-emulsion polymerization process. The chemical composition and core–shell structure were investigated by Fourier transform infrared (FTIR) spectrometry, differential scanning calorimetry (DSC) and transmission electron microscopy (TEM), respectively. Effect of MMA/BA mass ratio in the core and shell on the film-forming ability, Surface Tension of latex was also studied. Finally, water absorption and thermal stability of the latex films were characterized. It was found that the Surface Tension of emulsion can be reduced to 32.9 N/m when the MMA/BA mass ratio in the shell is 6/4. The water absorption of the latex film could be improved at a proper mass ratio of MMA/BA in core and shell, but adjusting the mass ratio of MMA/BA in the shell has little influence on the thermal stability of latex film. This work provides a method of preparing environment-friendly latex with Low Surface Tension and excellent water resistance for coating applications by regulating the mass ratio of monomers in a modified micro-emulsion polymerization process.

Low Surface Tension calcium hydroxide solution is an effective antiseptic.
International Endodontic Journal, 2007Co-Authors: S. V. Barbosa, Larz S.w. Spångberg, D. AlmeidaAbstract:Summary The antimicrobial effects of a saturated calcium hydroxide solution, and in combination with 10% and 20% detergent, were evaluated on Streptococcus faecalis. Strepto-coccus sanguis, Streptococcus mutans, Streptococcus salivarius, Neisseria sp., diphlheroid, Staphylococcus aureus, Lactobacillus sp., Staphylococcus epidermidis, Bacillus suhtilis and Candida albicans. The saturated calcium hydroxide solution was effective against only four of the 11 microorganisms studied over a 60-min exposure time. The calcium hydroxide solutions con-taining detergent killed all 11 test organisms over a 30-min exposure time. This difference was statistically significant (P0.01). However, the Low Surface Tension (46.5 × 10−3 Nm−1) and high pH (10.8) of the calcium hydroxide solution with 20% detergent establish it as the more effective solution.

Strepto-coccus sanguis, Streptococcus mutans, Streptococcus salivarius, Neisseria sp., diphlheroid, Staphylococcus aureus, Lactobacillus sp., Staphylococcus epidermidis, Bacillus suhtilis and Candida albicans. The saturated calcium hydroxide solution was effective against only four of the 11 microorganisms studied over a 60-min exposure time. The calcium hydroxide solutions con-taining detergent killed all 11 test organisms over a 30-min exposure time. This difference was statistically significant (P<0.01). No statistically significant difference in antimicrobial action was found between the 10% and 20% detergent calcium hydroxide solutions (F>0.01). However, the Low Surface Tension (46.5 × 10−3 Nm−1) and high pH (10.8) of the calcium hydroxide solution with 20% detergent establish it as the more effective solution.
