Description

Application

• Polystyrene-block-Polybutadiene-block-Polystyrene Triblock Copolymer Meets Silica: From Modification of Copolymer to Formation of Mesoporous Silica: Describes the preparation of mesoporous silica materials assisted by a PS-b-PB-b-PS triblock copolymer. This work involves functionalizing the copolymer with (3-mercaptopropyl) triethoxysilane via a thiol-ene radical addition, which is then employed to perform sol–gel reactions with tetraethoxysilane, providing insights into the multifunctional capabilities of these materials (R Yu, S Zheng, 2015).
