Synthesis of New Mesoporous Silica Particles, SPB2, From PPO-PEO-PPO and PEO-PPO-PEO Triblock Copoloymers for Drug Delivery Uses

Many types of materials with mesoporous architectures are currently being developed. Mesoporous silica particles developments are relevant to a number of diverse fields, suchas catalysis, membranes, molecularly tailored surface reactive solids, biomedical materials, and hybrid optics [1,2]. In thisstudy, a new mesoporous silica particle was synthesized by facile one-step sol-gel route using Pluronic F127 and PPG-b- PEG-b-PPG as the template, tetraethylorthosilicate as thesilica source, and ethanol as the co-surfactant under acid conditions. The synthesized particles were analyzed withTEM, SEM and Nitrogen adsorption-desorption analysis (BET). And then used as an adsorbent for benzoic acid to determine its adsorption-desorption capacity
