中文摘要：

通过静电纺丝法制备了直径为（320±51）nm的前驱体醋酸锌／聚氨酯（Zn（OAc）2／PU）复合纳米纤维。将前驱体先后经过0．1mol／LNaOH乙醇溶液和甘油浴热处理，得到ZnO纳米晶／PU复合纳米纤维。讨论了甘油浴温度和时间对纳米纤维结构和形貌的影响，研究了其吸附性能。实验结果表明，经过0．1mol／LNaOH乙醇溶液处理后，前驱体纤维zn（OAc）2／PU转变为ZnO／PU纤维且ZnO主要以低结晶和无定型态存在；再经过甘油浴处理后，低结晶和无定型态的ZnO转变为晶型完整的六方晶系纤锌矿结构，得到了ZnO纳米晶／PU复合纳米纤维，该纤维对有机染料分子罗丹明B有良好的吸附性能。

英文摘要：

Zn（OAc） 2/PU precursor composite nanofibers with diameter of （320 ± 51 ） nm were first fabricated by the electrospun technique. The precursor nanofibers were transformed into ZnO/PU composites fibers by hydroly- sis in 0.1 mol/L NaOH ethanol solution and solvothermally treated in glycerol oil bath. The effect of processing temperature and time on the structure and morphology of nanofiber was discussed. The adsorptivity of the ZnO/PU composites nanofibers was tested. The results showed that low crystalline and amorphous ZnO had been embedded in polyurethane （PU） nanofibers by hydrolysis in 0.1 mol/L NaOH ethanol solution, and low crystalline and amor- phous ZnO were transformed into hexagonal structured ZnO nanocrystallites by further treating in glycerol oil bath. ZnO/PU composites nanofibers had favorable adsorptivity to RhB.
