Yai. Abulebdeh et al., PREPARATION OF MESOPOROUS SILICA WITH POLY(OXYETHYLENE) POLY(OXYBUTYLENE)/POLY(OXYETHYLENE) TRIBLOCK COPOLYMERS AS TEMPLATES/, Journal of materials chemistry (Print), 8(8), 1998, pp. 1839-1842
The phase behaviour in neutral and acid aqueous solution is reported f
or two y(oxyethylene)/poly(oxybutylene)/poly(oxyethylene) (EBE) triblo
ck copolymers, of composition E33B10E33 and E43B14E43. Micellar soluti
ons of both copolymers were utilised for templated-silica synthesis un
der acidic conditions. Calcination of the silica products gave mesopor
ous materials. The E33B10E33-templated silica exhibited a spherical mo
rphology, whilst the E43B14E43-templated silica comprised irregularly
shaped particles.
