Özet

Carbon film was coated on the surface of ZnO chip by pyrolysis of poly (vinyl alcohol) with different polymerization degrees, and then longevity of a cut flower, such as carnation, was studied by adding carbon-coated ZnO chip in the vase filled with distilled water. In the results of optimum condition for coating ZnO with carbon, it was clarified that poly (vinyl alcohol) with polymerization degree of 2000 was suitable for forming homogeneously carbon at every portion in ZnO chip. From observation of carnation, it was found that the formation of carbon on ZnO chip was effective for longevity of a cut flower.
