Description
Technical field
The present invention relates to a kind of functional group compound, particularly a kind of can be formed surface wettability can with temperature change surface functional group compound.
Background technology
Temperature-sensitive macromolecular is that its structure of a class, physical properties, chemical property etc. vary with temperature and reversible change macromolecular material occurs.Common temperature sensing polymer comprises methacrylic acid N, chitosan of the polymkeric substance of N-dimethylethyl esters, the homopolymer of NIPA and multipolymer, Thermo-sensitive etc., obtains applying more and more widely in medicament slow release, separating substances, memory switch etc.In this patent, lowest critical solution temperature (the lowercriticalsolutiontemperature of described temperature-sensitive macromolecular, LCST) water-soluble polymer or part aqueous macromolecular material is referred to, below a certain temperature, in water, solvability is larger, and occur sharply to decline in the above solvability of this temperature, then this temperature is just called lowest critical solution temperature.
High by the material surface cross-linking density of UV-light (UV) solidification preparation, the hardness of better scratch resistance performance and Geng Gao can be realized compared with traditional thermoplastic or thermosetting material.In addition, ultraviolet light polymerization has the features such as fast, energy-conserving and environment-protective set time, suitability are wide.Thus prepare intelligent material by UV curing technology, resulting materials will be more durable.Thus, photo-curing material and traditional material are formed the composition with specific function, there is very large realistic meaning.
In daily life, common material all has comparatively fixing surface property under general conditions, for material surface wettability be also similar.Usually, the wettability of solid material is represented by contact angle, and running into many in life is the wetting situation of water to material, in this case generally all can characterize it with water contact angle.When water contact angle is less than 90 °, claim this material to be water wetted material, further when water contact angle is less than 5 °, be called super water wetted material; When water contact angle is greater than 90 °, claim this material to be hydrophobic material, further when water contact angle is greater than 150 ° and roll angle is less than 5 °, be called super hydrophobic material.Different wettabilitys gives material various different performance, and the material of such as good hydrophilic property can play good anti-fog effect, and the material that hydrophobicity is good then has good automatically cleaning ability.Generally, these functions of material are all short-terms, because common water wetted material has stronger water-soluble, water wetted material easily runs off after absorbing water, and in addition, the higher moisture of the medium-term and long-term maintenance of material itself is also quite disadvantageous concerning material; And the good material of hydrophobicity generally has certain lipophilicity, surface resistivity also can be comparatively large, and the organic composition in air and the impurity in environment are easier to be adsorbed onto its surface, so time one long hydrophobicity also can decline, practicality is also not bery high.
