【摘要】 本文报告了印刷材料表面自由能的测量原理和实验结果。通过测量H₂O和CH₂I₂与材料的接触角,由界面方程便可确定出材料的表面自由能（γ_s）、表面自由能的色散分量（γ_s^d）和极性分量（γ_s^p）。接触角测量采用显微拍摄液滴外形轮廓法,测量系统的随机误差（标准偏差）小于1.00。更多还原

【Abstract】 Principles and experimental result of surface free energy measurement of printing materials are presented in the report. Through measuring the contact angle between H₂O or CH₂I₂ and printing materials, surface free energy（r_s）, color dispersion component （r_s^d） and polarity component （ r_s^p） can be derived from interficial equation. Contact angle is measured by microphotographing the drip outline, the random （standard） error is less than 1. 00.更多还原
