Abstract

The surface modification of the tourmaline powder with triethoxyvinylsilane was studied to prepare the polymerizable organic tourmaline. The experimental results showed that the surface of modified tourmaline had the better hydrophobicity compared with unmodified tourmaline, when the mass ratio of triethoxyvinylsilane to tourmaline powder was 1∶5, and reacted at 60 ℃ for 1.5 h in the mixedsolvent of ethanol and distilled water (1∶5 in volume ratio). The structure characterization results indicated that the vinylsiloxane was introduced into the surface of tourmaline powder to generate the polymerizable organic tourmaline, and the crystal structure of tourmaline had no change.
