Formation and properties of core-shell pentablock copolymer/silica hybrids

Two novel core-shell pentablock copolymer/silica hybrids are prepared for coating applications, PDMM core/silica shell (PDMM@SiO2) and silica core/PDMM shell (SiO2@PDMM), by pentablock copolymer and 20% TEOS. The effect of different core-shell structure on the film hydrophobicity, water absorption, viscoelasticity, Tg, storage modulus and adhesion to the substrate is discussed.
