The invention discloses a super-hydrophobic film with a
composite structure, which comprises a film matrix, an
adhesive layer and a super-hydrophobic layer. The
adhesive layer is adhered to the film matrix; and the super-hydrophobic layer consists of micro-scale
powder particles and nano-scale
powder particles which are arranged at intervals and embedded into the film matrix, have low
surface energy or are modified by low
surface energy substances, and micro-scale protrusions and nano-scale protrusions are formed on the surface of the
adhesive layer. The super-hydrophobic film has the advantages of simple structure, easy preparation and lower cost; a
water contact angle of the super-hydrophobic layer is between150 and 165 degrees, and a roll angle is less than 5 degrees; the super-hydrophobic film is provided with the adhesive layer and has no special requirement on a matrix material; and a super-hydrophobic structure can be arranged on the matrix with higher
hardness; the super-hydrophobic film self has certain strength and
hardness and excellent
mechanical property, can be used in the occasions with higher mechanical requirements, and can also be used in the occasions needing water proofing,
pollution prevention, mist resistance,
snow cover resistance, ice
coating resistance, oxidation prevention and the like; and the super-hydrophobic film adopts the film matrix, occupies little space, and is convenient and simple to use.
