Dual-end functionalized magnesium organo-(phyllo)silicates via co-condensation and its antimicrobial activity

• Dual-end functionalized magnesium organo-(phyllo)silicates were synthesized.
• Both amino groups and phenyl groups of organo-(phyllo)silicates were anchored.
• Antimicrobial activities of organo-(phyllo)silicates were investigated.
• Spun fiber of a melting blend of organo-(phyllo)silicate/polymer was applied.

Organic–inorganic hybrid materials (organo-(phyllo)silicates) offer multiple functions with distinct properties. The design of mesolamellar talc-like organo-(phyllo)silicates composed of cation metal backbones with multiple organofunctionalities had significant benefits because the method is facile, environmentally benign and amenable to scale-up and processing. In this study, magnesium organo-(phyllo)silicate was synthesized using 3-aminoproyltriethoxysilane and phenyltriethoxysilane before characterization and yield optimization of the prepared organo-(phyllo)silicates, resulting in dual-end pendant functionalities with not only antimicrobial activities from amino groups but also thermal stability from phenyl groups. Exploiting the unique properties of organo-(phyllo)silicates, spun fibers were developed by organo-(phyllo)silicate/polymer melt blending to make a bacteriostatic toothbrush.
