Study About The Characteristic Of Bamboo Surface And Interface By The Treatment Of Low Temperature Plasma

In order to extract and utilize the properties of bamboo surface and interface sufficiently, from several points of view, such as wettability,chemistry composition,free radicals diversification,surface appearance,bonding strength of interface and so on, this paper analyses and studies the characteristic of bamboo surface and interface before and after the treatment of low temperature plasma. The conclusions of the paper have some direction meanings when dicussing the principle of the treatment of low temperature plasma to the surface and interface of bamboo. Expect to expand the appliance scope of plama and the force of bamboo material utilization when treated by plasma.Started with the changes of wettability of the surface of bamboo when treated by the low temperature plasma, the study found relatively great changes happened between Lifshitz-vander waals (LW) energy and alkali parameter. Thereinto the changes of Lifshitz-vander waals (LW) energy show that low temperature plasma bring some physics changes, the changes of alkali parameter show that low temperature plasma bring some chemistry changes.The research of chemistry composition and relatively free radicals concentration of the surface of bamboo show that the degree of oxygenation of bamboo green skin is better than that of bamboo yellow endothecium and the amplitude of free radicals concentration of bamboo green skin is outclass than that of bamboo yellow endothecium, when treated by the low temperature to the surface of bamboo. These conclusions validate the changes of alkali parameter with the treatment of the low temperature to the surface of bamboo.The researches of the SEM of surface appearance and bonding interface show that bamboo green skin and bamboo yellow endothecium represent different instance by the low temperature. After treated, the surface of bamboo green skin appears unsmooth holes, however, the surface of bamboo yellow endothecium appears reticulation interlaced structure form. These conclusions validate the changes of Lifshitz-vander waals (LW) energy with the treatment of the low temperature to the surface of bamboo.The paper also studies the wettability attenuation situation of bamboo surface after the treatment of low temperature plasma, results indicates that the period of validity of reactive group of bamboo green skin is 4-10 days, the period of validity of active group of bamboo yellow endothecium is 6-12 days.
