Abstract: The polythiophene/inorganic nanocomposites are classified according to the dimensions of each component. The preparation methods for such composites are reviewed. Besides the inherent properties of both polythiothene and inorganic matter，the excellent properties，such as electrical property and optical property，which arose from the synergism of the nanocomposites are emphasized. The mechanisms of enhancing performance are elaborated on the molecular scale.

摘要： 以各组分尺寸大小为基础对聚噻吩/无机物纳米复合材料进行了分类，详细阐述了各类材料的制备方法。同时强调了聚噻吩/无机物纳米复合材料除了具有聚噻吩、无机物的原有性能外，还会由于聚噻吩与无机物粒子之间的协同作用而具有优异的电性能、光性能，并从分子角度对这些性能提高的机理进行了阐述。
