接触角法研究聚合物表面的酸碱性质

A STUDY ON THE ACID / BASE PROPERTY OF POLYMER SURFACES BY CONTACT ANGLE METHOD

应用测接触角的方法研究了一组共聚物(MMA-Co-4Vp)的表面酸碱性质及其变化规律,应用“单极性”理论及其数据处理方法,定量求得了各共聚物表面的酸碱表面自由能参数(r_s^+,r_s^-)以及表面自由能的色散分量 r_s^(LW)。

By measuring contact angles,the surface acid/base properties and their va- riation rule of a series of copolymer(MMA-co-4-VP)are investigated.The surface ten- sion acid/base parameters(r_s^+ .r_s^-)and the dispersive force contribution(r_x^(LW)of these polymers are calculated according to the method of“monopolar”surface theory.
