摘　　要：在氨水环境下,以Zn(NO_3)_2为Zn^(2+)源,分别加入相同质量SDS和不同质量比例PVP的复合体系,采用水热法制备了不同形貌的ZnO微纳结构材料.通过XRD、SEM、气敏检测分析了ZnO材料的物相、结构、形貌以及气敏性能,研究了在复合体系中PVP对ZnO微纳结构材料气敏性能的影响.结果表明:所得ZnO微纳结构均具有红锌矿结构;当体系中m_(SDS)∶m_(PVP)=1∶1时,材料气敏性能最好,并提出了可能的影响机理.The nano-microstructure material of zinc oxide with different morphology have been prepared by hydrothermal method with zinc nitrate(Zn(NO3)2)as Zn2+sources in the ammonia environment,and the composite system of the same quality SDS and the different mass ratio PVP,respectively.Through XRD,SEM and gas sensitive detection,the influence of PVP on gas sensitivity performances of ZnO nano-microstructure material were studied in SDS-PVP composite system by analyzing the phase,structure,morphology and gas sensitivity.The experimental results show that the as-prepared samples are assigned to the hexagonal zincite of ZnO phase,and the gas sensitivity performances is the best with the weight ratio of 1∶1 of SDS and PVP.The possible influence mechanism is proposed.
