Superhydrophilic surface was achieved by plasma oxidation on SLA surface in the paper,which is deemed to highly enhance osseointegration between dental implant and bone.Titanium oxide surface was achieved by plasma oxidation process in vacuum chamber,which shows good hydrophilic property on the implant surface.The interface characteristic and variation of chemical composition in depth were studied thoroughly by XPS.The result shows that chemical composition gradiently change from top layer to Ti substrate,which is very important for the long term stability of the dental implant in vivo.Since this hydrophilic surface was unstable,further modification treatment is needed for the practical application.In this paper,plasma cleaning process was developed to recover superhydrophilicity of the implant surface.The results suggested that the introduction of such plasma oxidized surfaces in combination with plasma cleaning process before implantation operation improves hydrophilicity of dental implant,which,in turn,indicates the potential for improved implant osseointegration in vivo.

随着我国经济的迅速发展,城市化进程的加快,淡水资源短缺已成为制约我国经济可持续发展的重要因素之一,而工业化进程的加快,工业用水量的剧增,更是加剧了水资源不足的问题。工业生产中会产生大量高盐废水,若处理不当不仅造成水资源的浪费,而且严重污染环境。针对高盐污水水质成分复杂、盐度高和难处理的特点,本文提出了对高盐废水组成简化处理,进而采用低温多效蒸发技术对高盐废水进行脱盐处理工艺。首先采用Aspen P
