摘　　要：Poly(nickel 1,1,2,2-ethenetetrathiolate)(poly[Na_(x)(Ni-ett)])is one of the most promising n-type organic thermoelectric materials which can be used in wearable devices.However,the conventional solution method is time-consuming and the prepared poly[Na_(x)(Ni-ett)]usually has poor crystallinity,which does not benefit for achieving high thermoelectric performance.Here,a new one-step solvothermal method under the high reaction temperature and high vapor pressure was developed to prepare poly[Na_(x)(Ni-ett)]with a quite short period.The experimental results show crystallinity and electrical conductivity are greatly enhanced as compared with those prepared by conventional solution method.As a result,a maximum ZT value of 0.04 was achieved at 440 K,which is about four times of the polymer prepared by the conventional solution method.This study may provide a new route to enhance the TE properties of n-type organic thermoelectric materials.
