The tourmaline undecylenate was prepared by means of the surface organic modification of tourmaline powder with 10-undecenoyl chloride, and the reactive conditions have been optimized with the parameters of turbidity and contact angle of product. Experimental results revealed that the modified tourmaline have a good hydrophobicity when the ratios of 10-undecenoyl chloride to tourmaline was 1.0 and reacted 1.0 h at 50°C in DMF, and structure analysis of modified tourmaline was shown that the hydroxyl of tourmaline surface reacted with 10-undecenoyl chloride to get the polymerizable tourmaline undecylenate, and the crystal configuration of tourmaline has no changed.
