Abstract

Abstract:

In this paper, succinic anhydrides were copolymerized with vinyl acetate to get the p(SA-VA) with acid anhydride active group, and the surface modification of tourmaline was carried with p(SA-VA) as a modifier to prepare the tourmaline-containing functional polymer. The structure and morphology of the modified tourmaline and functional polymer were characterized by means of IR, XRD and SEM. The experimental results showed that the tourmaline was attached into the polymer by the reaction of the tourmaline surface hydroxyl groups with the anhydride group of P(SA-VA) to get tourmaline-containing functional copolymer, and it exhibited excellent dispersity and storage stability. And the membranes of the functional copolymer revealed good mechanical properties and excellent negative ion releasing, far infrared radiation performances.

Key words: tourmaline, surface modification, far infrared radiation, negative ion
