Description
Technical field
The invention belongs to the super two thin materials of polymer field, be specifically related to a kind of two thin property polymkeric substance and preparation method thereof, and the ultra-amphosphobic surface that is obtained by the thin property of this pair polymer manufacture.
Background technology
The topmost characterization parameter of moistened surface behavior is contact angle, if the static contact angle on surface less than 10 °, we are referred to as ultra-hydrophilic surface, if the surface has contact angle greater than 150 °, we are referred to as super hydrophobic surface.If the surface had both had super-hydrophobicity, super oleophobic performance is arranged again, we are referred to as super-double-hydrophobic surface.
Super hydrophobic surface is because its unique hydrophobic oleophobic performance, is supposed to or has been applied to a lot of aspects.Super-double-hydrophobic surface has self-cleaning function and can be used for sun power electroplax or minute surface that some need keep clean, such as the surface of gas kitchen ranges.Moreover metallic surface formation super-double-hydrophobic surface also can improve the corrosion resistance of metallic surface greatly.If construct super-double-hydrophobic surface at electric wire or high-voltage fence in addition, can avoid electric wire to form cryosphere at ice storm or Character of Snowstorm surface, thereby cause that short circuit causes cutting off the power supply plant downtime on a large scale, even cause the interruption of communications and transportation circuits such as railway.
Super-double-hydrophobic surface can form by a lot of methods, but the most basic condition is to allow the surface have very low surface tension, therefore consider fluorochemicals and fluoropolymer, plate the most cost-effective method that one deck fluorochemicals film just becomes preparation fluorine surface at material surface, can also keep composition and the character of material internal like this.Fluorochemicals can form fluorine-containing thin layer at substrate surface, even can be combined in substrate surface by the chemical bonding mode, thereby gives the surface super two thin characteristics, but this thin layer is owing to being that unimolecular layer is easy to be polluted or damage.And applications of fluoropolymers is in super-double-hydrophobic surface, then can provide surperficial one deck thicker fluorine-containing thin layer, be not vulnerable to corrosion such as solvent in actual use, simultaneously, difficult damage, but present used fluoropolymer is difficult between polymkeric substance and the substrate really be bonded together by the chemical bonding effect when forming super-double-hydrophobic surface, and mainly be physisorption, therefore there is potential hidden danger.Not only have the fluoropolymer feature but also can carry out the chemical bonding polymkeric substance with the surface if can develop, then can form real bonding, thereby make super-double-hydrophobic surface and substrate form one.
For the good super-double-hydrophobic surface material of practicality again of processability, many investigators have carried out number of research projects.Chinese patent file CN 101492829A has proposed a kind of method at the super two thin materials of metallic surface preparation, metal or metal alloy and copper or copper alloy are inserted in the perfluorinated aliphatic acid organic electrolyte solution as negative electrode and anode, carry out electrochemical reaction, can be at the super-double-hydrophobic surface of metal or metal alloy surface deposition one deck perfluorinated aliphatic acid mantoquita, same research group has proposed a kind of method at metallic copper or the super two thin materials of its alloy surface preparation at patent document CN 101492815A, base material is directly put into perfluorinated aliphatic acid organic solution soak, can obtain having the self-cleaning surface of super-double-thinning property.Chinese patent CN102021628A has proposed the preparation method of a kind of metal titanium or the super oleophobic surface of titanium alloy.Mainly be that titanium or titanium alloy surface are carried out obtaining the micrometer structure uneven surface after an anodic oxidation treatment, and then forming the layer of titanium dioxide nano-tube array structure by two-step anodization at micrometer structure, the modification through the low surface energy material obtains super oleophobic and super-double-hydrophobic surface then.Though above method raw material is simple and easy to, need integral surface through electrochemical reaction, the surface is the unimolecular layer of low surface energy simultaneously, is easy to be polluted or damage.
Chinese patent CN 101748461A has proposed a kind of aluminium or aluminum alloy sheet to be carried out obtaining the surface that the surface has super-double-thinning property with perfluor chain alkyl trichlorosilane or the processing of perfluor polymethacrylate again after two-step electrochemical is handled.There is the problem that cohesive strength is not enough or the surface is damaged easily equally in this method.Chinese patent CN 1379128A proposed a kind of with chemical gaseous phase depositing process preparation have ultra-amphosphobic can array structure thin film, but technology is relatively harsher, is not easy to suitability for industrialized production and uses.
