选择合适的ＳＤＢＳ／ 苯胺／ 水三组分Ｏ／Ｗ 微乳液与苯胺单体共存的两相体系，以单体相为单体源，在Ｏ／Ｗ 三组分微乳液中进行了苯胺聚合，成功地制备出了能够稳定分散于石腊油的聚苯胺微粒。并在四球试验机上研究合成条件、负荷、浓度对其摩擦学行为的影响。结果表明：聚苯胺有一定的减摩抗磨效果 The suitable two-phase system of SDBS / aniline / water tri-component O / W microemulsion coexisting with aniline monomer was synthesized by aniline polymerization in O / W microemulsion with monomeric phase as monomer source. Polyaniline particles that can be stably dispersed in paraffin oil were successfully prepared. And four-ball test machine on the synthesis conditions, load, concentration on the tribological behavior. The results show that: polyaniline has some anti-friction and anti-wear effect
