Description

Application

(3-Glycidyloxypropyl)triethoxysilane (GPTES) can be used as a reagent in the synthesis of:         

• Polymer nanocomposite membranes for direct methanol fuel cells (DMFCs).       
• Azido terminated poly(ethylene glycol) silane that can be self-assembled on a metal-oxide surface to facilitate the orthogonal biofunctionalization.      
• Epoxy functionalized silsesquioxane nanoparticles (SQ-NPs).
• Epoxy-functionalized mesoporous cellular foams (G-MCFs) as the support for the immobilization of penicillin G acylase (PGA).

GPTES can also be used as a precursor to prepare water-repellent, self-cleaning coatings.
