Abstract:In this paper， the six surface free energy（called surface energy） testing methods of paper literatures were studied. Based on the measured data of surface energy testing method by Zisman， other methods of Neumann， ZDY， HM， OWRK， and OCG were compared to obtain more convenient surface energy testing method of paper literatures with more consistent between theoretical data and measured data. The results showed that the surface energy measured by Zisman method was 26.24 mJ/m2. The surface energy would transform into a low value after sizing， and paper was difficult to wet. The results obtained by the Neumann method for measuring the surface energy of paper were relatively reliable， and the Neumann method could simplify the surface energy test to the greatest extent. In large-scale deacidification treatment， the Neumann method could improve the restoration efficiency of antique books and reduce damage to paper. The ZDY method was not suitable for measuring the surface energy of paper because of the large difference between measured data and theoretical data. The HM method gave a low deviation when diiodomethane and propanetriol were chosen as the testing fluids. The OWRK method and OCG method required the selection of appropriate testing fluids to reduce the standard deviation， and if the testing fluids were not selected correctly， conclusions might be drawn that do not correspond to reality.
