In recent years, super-hydrophobic/oleophobic material not only has important use in daily life, defends in national defense industry, medical treatment
The various fields such as raw have extremely wide application prospect.Super-hydrophobic/oleophobic fabric is because it has special wettability, simultaneously also
There are the performances such as Water-proof and oil-proof, antifouling, anticorrosive, freezing and automatically cleaning gradually to have been favored by people.Studies have shown that micro-nano
Compound coarse structure and low-surface-energy are the key factors that super-hydrophobic/oleophobic surface is formed.
Based on this, there has been proposed many methods for preparing super-hydrophobic/oleophobic surface, as LBL self-assembly method, colloidal sol-are solidifying
Glue method, plasma technology, electrochemical deposition method, etching method, phase separation method and template etc..However, the side of wherein most
Method complex procedures, technical process control is difficult, needs to use special equipment, and a part of method therein is also only applicable to
The flat surfaces of some special substances, it is difficult to be widely applied.
On the other hand, in textile finishing field, traditional fluorinated acrylate finishing agent mostly uses solution polymerization process system
, wherein most organic solvent is poisonous and harmful and volatile, although work well it is unhealthy not environmentally, and higher cost.
Furthermore it is 8 perfluoro capryl sulfonyl derivative (PFOS) and perfluorooctanoic acid that traditional fluorine-contained finishing agent, which mostly uses carbon atom number,
Compound (PFOA), they are considered to have excellent hydrophobic oleophobic characteristic and good surface-active.However PFOS is a kind of
Chemical stability is high, and the perfluorocarbon compound with durability, bioaccumulation and toxicity, not degradable in the environment, and
There is harmfulness and potential carcinogenicity to organism, PFOS has been that European Union member countries are forbidden to use and import.
