摘　　要：以阳极氧化法制备的双层多孔阳极氧化铝(PAA)为模板,采用旋涂的方法,制备了双层聚甲基丙烯酸甲酯(PMMA)纳米柱阵列。以二甲基甲酰胺(DMF)为溶剂添加PMMA固体颗粒,溶解得到PMMA/DMF高聚物溶液,讨论了PMMA∶DMF的质量配比分别为1∶9、1∶6、1∶4时制备的双层PMMA纳米柱阵列的生成情况。结果显示:PMMA∶DMF的质量配比为1∶6时制得的双层PMMA纳米柱阵列质量最好,纳米柱阵列排列整齐,无明显粘连,黏度值为154.64MPa·s;PMMA∶DMF质量配比为1∶9和1∶4时制得的纳米柱阵列粘连严重。采用模板/旋涂法制备的具有大比表面积的PMMA纳米柱阵列可以用于生物传感器、超疏水材料的制备等,有广阔的应用前景。Double layer PMMA nano-pillar array was fabricated by spin coating method,which using double layer PAA as template.DMF as the solvent to obtain PMMA polymer solution,on the basis,the fabrication condition of PMMA nano-pillars was discussed by performing PMMA/DMF at the mass ratio of 1∶9,1∶6,1∶4,respectively.Results showed that PMMA nano-pillar array with best quality was obtained at the mass ratio of 1∶6.PMMA nano-pillar array existed serious blocking phenomenon,when the mass ratio was 1∶9or 1∶4.PMMA nano-pillars array with large surface area fabricated by template/spin-coating method could be used to fabricate biosensors and superhydrophobic materials,which had broad application prospects.
