The surface tensions of methanol, acetone, dimethylformamide, dimethylsulfoxide, and methylamine over limited temperature ranges, and of solutions of alkali halides in the first three of these liquids at 25 °C have been measured by the method of maximum bubble pressure, with precautions against moisture. The data for the pure liquids are compared with literature data where these exist. The results for the solutions are discussed in the light of various existing theories.

Self-assembling behavior of block copolymers having water-soluble portion as one of the blocks plays key role in the properties and applications of the copolymers. Therefore, we have synthesized block copolymers of different block length and investigated their self-assembling behavior with reference to concentration and temperature using surface tension and conductance measurement techniques. The results obtained through both techniques concluded that critical micelles concentration (CMC) was decreased from 0.100 to 0.078 g/dL with the increase in length of water insoluble block and 0.100 to 0.068 g/dL for the increased temperature.ΔGmicwas also decreased with the increase in temperature of the system, concluding that the micellization process was encouraged with the increase in temperature and block length. However,ΔHmicvalues were highest for short block length copolymer. The surface excess concentration obtained from surface tension data concluded that it was highest for short block length and vice versa and was increased with the increase in temperature of the system. However, the minimum area per molecule was largest for highest molecular weight copolymers or having longest water insoluble block and decreases with the increase in temperature.
