低温等离子体技术在粉体表面处理中的应用

Application of Low-temperature Plasma Technology in Surface Modification of Powder

低温等离子体技术用于粉体表面处理具有工艺简单、无需溶剂、节能高效等特点。等离子体处理粉体表面利用的放电形式从真空放电到空气压力下的气体放电;范围从无机粉体的表面处理到纳米粉体、有机粉体的表面处理都有涉及。评述了国内外利用等离子体对无机粉体、有机粉体低温等离子体表面处理技术的进展。

The surface modification of powder using the low-temperature plasma technology has advantages such as simple operation, solvent-free, energy-saving and high efficiency etc. The form of discharge of low-temperature plasma includes vacuum and atmosphere; the categories of powders treated have inorganic and organic particles. The progress of surface modification of powders by low-temperature plasma at home and abroad is presented in this article.
