摘要:采用醋酸锌、乙醇和乙二醇甲醚比例为1 g200 μL10 mL配制ZnO前驱体溶液,然后将其旋涂在湿纤维素膜表面,进一步通过退火处理获得性能优异的纤维素/ZnO复合膜,并以纤维素/ZnO复合膜为衬底制备透明导电膜。研究表明,提高退火温度,纤维素/ZnO复合膜的透光率呈现先降低后趋于平稳的趋势。当旋涂转速为2000 r/min,退火温度为23℃时,纤维素/ZnO复合膜的透光率高达89.6%,升高退火温度至160℃,复合膜的透光率降低至86.3%。退火温度和旋涂转速会影响纤维素/ZnO复合膜的热稳定性能,升高退火温度和旋涂转速会提高复合膜的热稳定性能。在80℃和2000 r/min的处理条件下,可以制备形貌比较均匀的纤维素/ZnO复合膜;与纤维素膜相比,以纤维素/ZnO复合膜为衬底制备的透明导电膜,其电阻降低约65%。
Abstract:In order to prepare a transparent conductive film based on a cellulose/ZnO composite film, the ZnO precursor solution was prepared from zinc acetate,ethanol and ethylene glycol methyl ether based on the ratio of 1 g200 μL10 mL respectively, and then it's compounded with the cellulose film.Desirable cellulose/ZnO composite film was harvested by spin-coating and annealing treatments. The results showed that the increase of annealing temperature could slightly decrease the transparency of cellulose/ZnO composite film then following by a plateau. The cellulose/ZnO composite film presented a superior transparency of 89.6% at 23℃ of annealing temperature and 2000 r/min of spinning speed, and its transparency decreased of 86.3% due to the 160℃ of annealing temperature.In addition, both spin-coating and annealing treatments made important effect on the thermal stability of cellulose/ZnO composite film, where the thermal stability was promoted due to the improvement of annealing temperature and spinning speed. A desirable cellulose/ZnO film with uniform morphologies was prepared under the conditions of 80℃ of annealing temperature and 2000 r/min of spinning speed .
