The application discloses a kind of visible light super-transparency super-smooth homogeneous film and preparation method thereof, belong to functional film preparation technical field.The application is with
polydimethylsiloxane as only matrix
material quality, add
volatile agent, cooperate PDMS special curing agent to prepare first PDMS composition;It is coated in glass substrate and solidified,
volatile agent is volatilized to form porous PDMS bottom layer;Again, low
viscosity liquid PDMS of same material is scraped to the surface of bottom layer, forms liquid lubricating layer, finally obtains the super-transparency super-smooth film of homogeneous
composite structure, the film visible light
transmittance is greater than or equal to 95%,
water contact angle is greater than or equal to 150 °, sliding angle is less than or equal to 5 °, solve the problem that traditional nano SiO2 modified PDMS film light
transmittance is low, and the adhesion between heterogeneous
layers is poor, and process is simple, low in cost, applicable to high-end
optical field such as photovoltaic panel.
