It is favorable for the increase of the adsorption film thickness by increasing the lyophobic chain.The determination of adsorption film thickness verifies the validity of the modification result. 木钠及改性木钠在疏水性和亲水性固体表面的吸附层厚度不同，其分子疏水链段的增加有利于增大其在疏水性（煤）表面的吸附厚度。
AB-I and AB-II show the similar phenomenon in bulk phase transition,but not very similar in methanol and ethanol.Perhaps this is because of competition between hydrophile and lyophobic. AB-I和AB-II在电解质溶液中表现出类似的体积相变规律，而在甲醇、乙醇中表现出不尽相同的相变规律，这可能是由于AB-II中存在亲水力和疏水力相互竞争作用的结果。
