Abstract
Provided is a degradable super-hydrophobicity plastic film. Honeycomb structure is formed on the surface of the plastic film. The plastic film is connected and piled in a plurality of ball structure. The ball structure distributes randomly. A contact angle formed between the film and water is 156.8 degrees-159.4 degrees. The super-hydrophobicity plastic film is prepared from, in a cheap and environmental friendly material-polyglycolic acid. The preparing method is simple and the processing condition is easy to control. Thereby, the uniform and large area super-hydrophobicity film can be prepared with a great actual application value.
Description
Technical field
The present invention relates to a kind of hydrophobic film material, particularly relate to a kind of super-hydrophobicity plastic sheeting.
Background technology
Surface wettability is one of key property of the surface of solids, is also an extremely common class interfacial phenomenon, and it is direct
Affect the various vital movements of organism in nature, and also play an important role in life in the production of the mankind.Gu
The wettability of surface is made up of its surface chemistry and micro-geometry together decides on.And super hydrophobic surface is special as having
The one on wellability surface, can be used to waterproof, antifog, snow defence, dust-proof etc..So-called super hydrophobic surface generally refers to and the contacting of water
The surface more than 150 °, the angle.The method preparing super hydrophobic surface at present has a variety of, such as, and electrospinning, the method for solution, mould
Plate synthetic method, plasma polymerization or etching, silicon fluoride modification etc..But the raw material that many counting methods are used or equipment are more high
Expensive, or preparation condition is harsh, wastes time and energy.Especially being difficult to prepare large-area based superhydrophobic thin films, these all limit it
Broad practice.So preparing low-cost large-area based superhydrophobic thin films in the urgent need to the most time saving and energy saving method
Meet and be actually needed.
Summary of the invention
The present invention solves that the problems referred to above provide one and prepare convenience, lower-cost degradable super-hydrophobicity plastics
Thin film.
The technical solution used in the present invention:
A kind of degradable super-hydrophobicity plastic sheeting, surface is cellular, many near-spherical structures connections pile up and form,
The contact angle of random distribution, thin film and water is between 156.8 °～159.4 °.
Described degradable super-hydrophobicity plastic sheeting, its preparation process is as follows:
(1) poly (propylene carbonate) (PPC) and polylactic acid (PLA) are the most accurately weighed, by the mixing of PPC and PLA
Thing is configured to oxolane (THF) solution that mass fraction is 7%；
(2) with spin coating instrument, the solution of preparation in step (1) is spread evenly across on glass substrate, places 2h, make solvent fill
Degradable plastic film is formed after dividing volatilization；
(3) dimethyl being then immersed in certain temperature range by the degradable plastic film formed in step (2) is sub-
In sulfone (DMSO), take out after certain time, naturally dry, prepare the super-hydrophobic plastic sheeting of degradable.
Described degradable plastic film soaks the temperature range 50 DEG C～70 DEG C in dimethyl sulfoxide (DMSO), during immersion
Between 22～28min.
Beneficial effects of the present invention: the present invention is so that one is cheap and environmental friendliness shaped material polylactic acid prepares super-hydrophobic moulding
Material thin film, preparation method is simple, and easy control of process conditions can be prepared based superhydrophobic thin films uniform, large-area, have relatively
Big actual application value.
