Nanocrystalline porous Cu films were prepared on glass subtrates by sol-gel spin coating technique with copper(II) acetate as raw material and NH(C2H2OH)2as chelating agent. The characteristics of films were analyzed by IR, TG-DTG, XRD and SEM. The structure of Cu films was remarkable influenced by sol concentration and PEG content. The effects of calcining temperature and the way of the gelation on grain size were discussed. The results showed that the pore size and density are homogeneous when the sol concentration was 0.6 mol/L and the PEG content was 0.35 g.
