摘　　要：合成不同相对分子质量的聚丙烯酸(PAA)，并以之为模板，在稀溶液中利用离子的自组装合成CuS中空纳米棒，棒平均直径在60～70nm之间。结果表明，PAA可很好地作为室温下合成CuS纳米棒的模板剂，体系的pH值、PAA浓度、PAA相对分子质量等条件对生成物的微观形态均有影响。Polyacrylic acid with different molecular weight has been synthesized and be served as patterns to induce the synthesis of hollow CuS nanorods by self-assembly in dilute solution. The rods have an average diameter of 60~70 nm. The results showed that polyacrylic acid could be served as a very simple structure-directing agent for a synthesis of CuS nanorods at ambient temperature. The microcosmic morphology of the resultant was influenced by pH value of the system, concentration and molecular weight of PAA as well as other conditions.
