The block polyethers with different structure and composition were synthesized by anionic polymerization and used to disperse single-walled carbon nanotubes (SWNTs). The block polyethers with the structure of branch or benzene ring had better dispersion ability than the commercial Pluronic block polyethers (L64 and F127). In order to compare the parameters, dispersion limit and efficiency of polyethers...
Nanosized silica was synthesized by the hydrolysis and condensation of tetraethyl orthosilicate (TEOS) in polyoxyethylene (10) tertoctylphenyl ether (Triton X-100)/cyclohexane/ammonia reverse micelle. The effects of [H 2 O]/[Triton X-100] (R), ammonia concentration on the size and morphology of the spherical silica were investigated thoroughly. The size of silica displayed an interesting variation...
