Chloroform surface tension
WebSep 20, 2010 · Basically, I compared the vicosity and surface tension of both water and glycerol through a series of tests and was rather surprised at what I found. According to my results (and data books when I checked), water has a higher surface tension than glycerol, but glycerol is more viscous than water.

WebApr 10, 2024 · Water and diiodomethane, two solvents with different polarities, are used to measure the contact angles of different materials. The results are shown in Fig. S7. From the measurements, the surface tension of PM6, FA-C9, FA-C12 and FA-C16 are estimated to be 33.6, 34.6, 27.5 and 23.9 mN m −1, respectively.
