ABSTRACT

Expound the synthetic methods of the fluorocarbon surfactant gas-wetting
alteration agent and polymer gas-wetting alteration agent, expound the effect
of realizing the gas wettability of solid surface, and discuss the application
conditions and influencing factors of these two kinds of gas-wetting alteration
agents; research the mechanism of the gas wettability of solid surface by the
methods, such as distribution of fluorine elements, on the solid surface, quan-
tum chemistry, etc.

Fluropolymers are the main gas-wetting alteration materials and they are rela-
tively simple. The free surface energy of fluorine materials is lower, and per-
fluorinated group is both hydrophobic and oleophobic, which obviously
