High PVC film‐forming composite latex particles via miniemulsification,part 1: Preparation

Miniemulsification technology was used to encapsulate TiO₂ particles inside a styrene/n‐butyl acrylate copolymer with high loading levels (11 to 70% PVC (pigment volume concentration)). In this approach, a St/BA copolymer dissolved in toluene in the presence of a costabilizer (hexadecane) was mixed with a dispersion of TiO₂ particles in toluene and sonified, and then emulsified in an aqueous surfactant solution by sonification. The effect of sonification time on both the dispersibility of the TiO₂ particles in the presence of the copolymer and hexadecane and on the encapsulated particle size was investigated. Particle size analysis by dynamic light scattering showed that these composite latexes are quite stable. It was also found that as the TiO₂ loading increased from 11 to 43% PVC, the particle size of the TiO₂ dispersion decreased while the polymer‐encapsulated TiO₂ particle size increased. The effect of surfactant concentration (sodium lauryl sulfate, SLS) on the encapsulated particle size was investigated using four different SLS concentrations in the 11% PVC system. The results showed that as the SLS concentration increased the particle size decreased, as expected. Also it was found that the minimum surfactant concentration that gives stable encapsulated TiO₂ particles is above 10 mM SLS. The role of HD in the recipe was studied for an artificial latex containing no TiO₂ and one prepared at 11% PVC, in terms of particle size before and after solvent stripping, and its effect on the T_g. © 2006 Wiley Periodicals, Inc.

过量TiO2助烧剂对Ba0.998La0.002TiO3陶瓷晶粒生长的影响

采用电性能测定和微观结构分析等方法研究了过量TiO2助烧剂对Ba0.998La0.002TiO3陶瓷晶粒生长的影响.结果表明:对于Ba0.998La0.002TiO3陶瓷在有液相参与烧结的晶粒溶解-淀析过程中,晶粒生长的必要条件是不仅要有液相的形成,而且BaTiO3晶粒必须在液相中有一定的溶解度.由于BaTiO3晶粒在Ba6Ti17O40和Ba2TiSi2O8液相中有足够的溶解度,促进了晶粒的生长,同时旌主掺杂离子进入晶格而释放氧,形成半导性的陶瓷,而BaTiO3晶粒不能溶解于Ba2Ti2SiP2O13液相中,抑制了晶粒的生长.
