Studies on Lauroyl Chloride Modified Tourmaline Powder
The surface modification of the tourmaline powder with lauroyl chloride was studied in this paper, and discussed the influence of reaction conditions on modified effect with parameters of activation index and contact angle. Results showed that the activation index of modified tourmaline powder reached to 96% while tourmaline powder reacted with equiponderant lauroyl chloride at 80 °C in DMF for 5 hours, and the modified tourmaline had excellent hydrophobic property. Structural analysis revealed that hydrophobic alkyl was attached to the surface of tourmaline powder, but it had no effect on the crystal configuration of tourmaline powder.
