Used as a surface modifier in silica-based materials, such as glass, silica gel, or nanoparticles, enhancing compatibility between organic polymers and inorganic substrates. Commonly applied in sol-gel processes to improve adhesion, dispersion, and stability in coatings, composites, hybrid materials, and sensors. Acts as a coupling agent in nanomaterial synthesis, promoting uniform functionalization of surfaces.

The positively charged imidazolium group provides antimicrobial properties, making it suitable for materials requiring resistance to microbial adhesion.

Also utilized in the preparation of ionic liquid-modified silicas for catalysis, separation technologies, and carbon capture, due to its stable imidazolium cation and reactive silane group. Serves as a precursor for synthesizing ionic liquids with silyl groups, which can be embedded in silica matrices to create functional materials.
