为了探明不同类型碳纤维表面能差异以及上浆剂对表面能极性、色散分量的影响规律，利用Wilhelmy吊片法、OWRK理论获得了去除上浆剂前后的碳Ⅲ、碳Ⅶ、M40、M40JB和M55JB碳纤维表面能及其色散、极性分量。结果表明，碳纤维表面能从大至小依次为碳Ⅲ、M40、M55JB、M40JB和碳Ⅶ，而极性分量占11％~25％。去除上浆剂后极性分量下降较为明显，碳Ⅲ、碳Ⅶ、M40和M55JB分别下降了56％、21％、18%和16%，而M40JB去除上浆剂前后极性分量变化不大，这可能与上浆剂中含有的极性官能团有关。
為瞭探明不同類型碳纖維錶麵能差異以及上漿劑對錶麵能極性、色散分量的影響規律，利用Wilhelmy弔片法、OWRK理論穫得瞭去除上漿劑前後的碳Ⅲ、碳Ⅶ、M40、M40JB和M55JB碳纖維錶麵能及其色散、極性分量。結果錶明，碳纖維錶麵能從大至小依次為碳Ⅲ、M40、M55JB、M40JB和碳Ⅶ，而極性分量佔11％~25％。去除上漿劑後極性分量下降較為明顯，碳Ⅲ、碳Ⅶ、M40和M55JB分彆下降瞭56％、21％、18%和16%，而M40JB去除上漿劑前後極性分量變化不大，這可能與上漿劑中含有的極性官能糰有關。

To explore the difference of surface free energy among different types of carbon fibers and the effect of sizing on surface free energy, the surface free energies and the dispersion/polar components of CarbonⅢ、CarbonⅦ、M40、M40JB and M55JB are determined by wilhelmy hanging plate method and OWRK theory. The results indicate : the rank of total surface free energy is CarbonⅢ>M40>M55JB>M40JB>CarbonⅦ, the distribution of polar component is about 11%~25%. The polar component declines obviously without sizing, the reduction of CarbonⅢ、CarbonⅦ、M40 and M55JB is 6%, 21%, 18%, 16%, respectively, the polar component of M40JB changes a little, that perhaps depends a lot on the number of polar groups in sizing.
