General description
3-(Trimethoxysilyl)propyl methacrylate (TMSPMA) is widely used as a monomer and as a coupling agent in polymerization reactions. It copolymerized with other monomers, such as styrene or acrylates, to produce polymer films with improved mechanical properties and adhesion to various substrates. It also improves the stability of the polymer to UV radiation. Additionally, TMSPMA is also used as a crosslinking agent in polymer gels, as it reacts with other functional groups, such as hydroxyl or carboxyl groups, to form stable covalent bonds that improve the mechanical properties of the polymer. Furthermore, TMSPMA has also been used in various fields which include, lithium-ion batteries, engineering applications dental restorative materials, and various other biomedical applications.
Application
3-(Trimethoxysilyl)propyl methacrylate (TMSPMA) can be used as:
- A linker molecule to synthesize a scaffold based on a TMSPMA-polyhedral oligomeric silsesquioxane (POSS) hybrid for potential tissue engineering applications.
- A coupling agent in the preparation of visible-light-curable urethane-modified epoxy acrylate/SiO2 composites to improve the adhesion between the filler, SiO2 nanoparticles, and the resin matrix. These composites are further applicable as dental restorative materials.
- A monomer to synthesize a polymer electrolyte material for use in lithium-ion batteries.
- A silane coupling agent for the modification of TiO2 nanoparticles. TMPSM-modified nano-TiO2 shows excellent stability in water which makes it suitable for polymer nanocomposite processing.
- A monomer in the synthesis of reactive block copolymers via atom transfer radical polymerization. These block copolymers can be used to construct a variety of hybrid nanomaterials.
