Description
Technical field
The present invention relates to provide a kind of isotactic polyprophlene/urethane based superhydrophobic thin films and preparation method thereof.Prepare isotactic polyprophlene/urethane based superhydrophobic thin films with solution method, with and in the purposes of biomedical materials field.
Technical background
(the A.L.Demirel of H.Y.Erbil seminar, Y.Avci, O.Mert) on the Science periodical, delivered research article (the 299th volume in 2003, the 1377-1379 page or leaf), they find that utilize 1, the mixed solvent of 4-dimethylbenzene and methylethylketone can make isotactic polyprophlene (water contact angle the is 156o) powdered object with good ultra-hydrophobicity, but it is to assemble the powdered object that forms with nanoparticle, and mechanical property completely loses (Fig. 1).In order to enlarge the range of application of the ultra-hydrophobicity that isotactic polyprophlene shows, we attempt the mechanical property that a lot of methods remove to improve isotactic polyprophlene, for example have the methods such as material blend of excellent mechanical performances with some.
Summary of the invention
Necessity and importance at isotactic polyprophlene mentioned in the above-mentioned technical background/urethane based superhydrophobic thin films preparation method and application, the object of the invention is to provide a kind of preparation with isotactic polyprophlene/urethane based superhydrophobic thin films of certain convex-concave structure, and applies it among the fields such as biological medicine.
As everyone knows, urethane is the polymkeric substance that a class has good biocompatibility, very good mechanical properties.The present invention searches out a kind of suitable solvent xylene, and dissolving isotactic polyprophlene and urethane merge two kinds of materials mutually under 110 ~ 155 ℃ of high temperature, form a kind of novel composite material.Because isotactic polyprophlene material nano particle itself used in the present invention has good super-hydrophobicity, therefore new matrix material had both kept the ultra-hydrophobicity of original isotactic polyprophlene material, simultaneously since isotactic polyprophlene and urethane to have formed blend even, the good mechanical performance of urethane and adhesion film-forming properties are that the mechanical property of improving the isotactic polyprophlene material has been made contribution.Be faint yellow semitransparent thin film after isotactic polyprophlene and the polyurethane comixing film forming, certain mechanical strength is arranged, with the powdered object (white, frangible) of isotactic polyprophlene material preparation originally very big difference is arranged, have good ultra-hydrophobicity simultaneously again.Trace it to its cause: the ultra-hydrophobicity of (1) isotactic polyprophlene material nano particle itself; (2) two kinds of intermingling materials form convex-concave structure makes novel material that certain roughness be arranged, thereby has kept good ultra-hydrophobicity.
Isotactic polyprophlene of the present invention/urethane based superhydrophobic thin films, be with urethane and isotactic polyprophlene in dimethylbenzene, dissolve, film forming and making after the blend.
Above-mentioned isotactic polyprophlene/urethane based superhydrophobic thin films, water contact angle is greater than 150 °.
The invention also discloses the preparation method of above-mentioned isotactic polyprophlene/urethane based superhydrophobic thin films, is dissolving in dimethylbenzene, blend and film forming with urethane and isotactic polyprophlene.
Concrete technology approach is: prepare isotactic polyprophlene/urethane based superhydrophobic thin films with solution method, promptly adopting dimethylbenzene is solvent, stirring is provided, 110 ~ 155 ℃ down dissolving isotactic polyprophlene particle, bio-medical level polyurethane particles (mass ratio of isotactic polyprophlene and urethane is 50:50 ~ 95:5), film forming is poured out in blend.
Isotactic polyprophlene of the present invention/urethane based superhydrophobic thin films has excellent biological compatibility.And contact experiment with hemocyte, thrombocyte with this film, and find no adhesion behavior, can realize purposes as bio-medical material.
