A mode of the directionally growth of PAn on the surface of NaFe〓P〓rod-like particle was suggested. Some of aniline molecules in the reactants are fixed on the surface of skutterudite particles before the beginning of the polymerization. Other aniline molecules link with the aniline molecules fixed on the surface of skutterudite and form liner chains when the initiater is added into the reactants.

The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.
