Synthesis of new mesoporous silica particles with high porosity from block copolymers

The synthesis of new mesoparticles based on silicone has gained a new peak in recent developments in the areas of catalysts support, absorbance, drug release, and biomedicalapplications of polymerization reactions or polymers.[1,2] The higher surface area and porosity with a specific geometryand architecture has been considered important aspect of in this area. In this study we have replaced cetyltrimethyl ammonium bromide with two block copolymers made of PPG-PPE-PPG and PEO-PPG-PEO known as Pluronics, and added chyclohexanol co surfactant to synthesize new siliconeparticles from tetraethoxyslilane in the aqueous solution with citric acid catalyst. The silicone particles form a polymeraccording to the following reactions
