One of the urgent research topics for preservation of modern and contemporary paper relics is the rapid and economical deacidification of papers without damaging textural qualities such as tensile and folding properties. In this paper, plasma technology was used to effectively reduce the acidity of paper at room temperature and atmospheric pressure, so as to avoid crinkling and the alteration of seen using traditional wet methods. Positive deacidification results were achieved by adjusting treatment parameters, such as energy density, processing times, etc. The pH value of the paper samples rose from 5.0~6.0to above 7.0~8.0after deacidification for 5minutes. The texture of the paper texture remained stable, with no chromatic aberrations, and there was a small increase in the tensile strength that remained at over 95% after artificial aging treatments. It can be concluded that the plasma deacidification technique can be applied to machinemade paper of various ages and condition of preservation. The method can be widely used as a deacidification method.
