Articles including durable and icephobic and / or biocidal polymeric coatings are disclosed. The polymeric coatings can include a bonding layer which may contain a substantially fully cured polymeric resin providing excellent adhesion to metallic or polymer substrates. The polymeric coating further includes an outer surface layer which is smooth, hydrophobic, biocidal and icephobic and, in addition to a substantially fully cured resin, contains silicone comprising additives near the exposed outer surface. The anisotropic polymeric coatings are particularly suited for strong and lightweight parts required in aerospace, automotive and sporting goods applications. A process for making the articles is disclosed as well.

The invention discloses an integrated forming method of a polymer material with a covering ice preventing function. By designing the mold surface structure and adjusting the forming hot-pressing parameters of a composite material, integrated forming of a covering ice preventing function structure and a polymer-based material is achieved. The polymer material with the covering ice preventing function and the integrated forming method thereof have the following advantages that the two functions of preparation of the polymer-based material and integration of the covering ice preventing micro-structure on the material are finished at the same time; compared with the traditional technology, operation is simple, the structure forming property is good, and the micro-structure distribution is uniform; the prepared polymer material has the surface with the super-hydrophobicity to the liquid-state water, the freezing time of supercooling liquid drops is prolonged remarkably, and thus the supercooling liquid drops have enough time to leave the surface; and the ice adhesion strength is extremely low, the covering ice can be separated from the material surface under the action of natural wind force or gravity, and the polymer material can be used for covering parts, which are exposed in the extreme environment, on the outer surface of machine equipment and has the important practical significance to the ice preventing and removing technological development of a wind power machine and an airplane.

The invention belongs to the technical fields of chemistry and chemical engineering, and relates to an icing-proof coating with low ice adhesion, and a preparation method and application thereof. The icing-proof coating provided by the invention is composed of an inorganic material and a cross-linked hydrophilic polyelectrolyte. The inorganic materials and the cross-linked hydrophilic polyelectrolyte are mixed and subjected to ball milling, and then coated on a substrate film, and cured to form the icing-proof coating. The inorganic material improves surface mechanical properties and wear resistance of the icing-proof coating, while the hydrophilic cross-linked polyelectrolyte ionizes a large amount of ions after water absorption; the ion solution with high concentration lowers the freezing point of water and enables an unfreezing water film to be formed on the surface of the icing-proof coating; therefore, a lubricating layer is introduced between ice and the surface of the icing-proof coating, so that the ice later on the substrate surface layer breaks away from the substrate surface under the action of gravity or wind to realize the icing-proof effect.

The invention relates to benzoxazine type super-hydrophobic nano silicon dioxide as well as a preparation method and application thereof, belonging to the technical field of nano material modification and application. The benzoxazine type super-hydrophobic nano silicon dioxide is prepared by the following step: stirring benzoxazine and a solvent thereof, silicon dioxide nanoparticles and water for 0.5-2 hours at 20-50 DEG C in microwave condition. The water contact angle of a coating prepared from the benzoxazine type super-hydrophobic nano silicon dioxide is larger than 150 degrees, and the roll angle is smaller than 10 degrees while the coating has good anti-icing performance; compared with a metal aluminum surface, the ice adhesion strength on the surface of the anti-icing coating is reduced to 50% or below; at low temperature, the ice cover is reduced to 50% or below; and the water icing delay time on the surface of the anti-icing coating is longer than 30s.

The invention discloses an anti-sticking ice coating for a mine car and a preparation method thereof, and belongs to the technical field of anti-sticking ice coatings. The anti-sticking ice coating for a mine car is composed of A component and B component; wherein the A component is composed of Composed of the following raw materials: epoxy-modified silicone resin, functional filler, dispersant, wetting agent, active leveling agent, etc.; component B is composed of the following raw materials: crosslinking agent and second solvent; mine car of the present invention The anti-sticking ice coating uses epoxy modified silicone resin as the base material. The base material not only has the advantages of low temperature resistance and strong hydrophobicity of silicone resin, but also is modified by epoxy resin. Due to the unique epoxy resin Active groups such as radicals, hydroxyl groups, ether bonds, etc., so the epoxy resin modified silicone resin can significantly improve the adhesion of the coating.
