Problems solved by technology

On the one hand, the current method needs to prepare a highly rough surface by complex methods (such as etching, electrochemical deposition, layer-by-layer self-assembly, etc.), which involves specific equipment, harsh conditions and long periods, and is difficult to use On the other hand, the lubricating oil on the surface will be gradually lost due to volatilization and fluid entrainment, and the ultra-smooth surface performance of the Nepenthes imitation will gradually become similar to that of the Nepenthes imitation. Superhydrophobic surface transition of the leaf effect

Abstract

The invention discloses a functional filler with a self-lubricating surface and used for creating the simulated common nepenthes effect, in particular an aerogel loaded cleaning functional filler which is prepared by aerogel particles and lubricants. The aerogel loaded cleaning functional filler can be used for compositing with macromolecule and other base materials to prepare self-lubricating bionic surfaces. The functional filler can seal lubricants inside base materials to let the lubricants seep out gradually, thereby having a slow release effect. On one hand, the aerogel loaded cleaning functional filler can overcome the defect of easy loss of the smooth and porous surface lubricants for creating the simulated common nepenthes effect in an infiltration method , and on the other hand, as there is no need to create a coarse surface structure on the self-lubricating surface for creating the simulated common nepenthes effect, it is favorable to realize industrial application of the functional filler, such as being used in marine antifouling materials, frost prevention materials, anti-icing materials and oil-water separation materials.

Description

technical field [0001] The invention relates to a functional filler which can be used to construct a self-lubricating surface with bionic nepenthes effect, in particular to an airgel-loaded cleaning functional filler and its preparation and application. Background technique [0002] The self-lubricating surface of biomimetic Nepenthes has the advantages of anti-adhesion of organic liquids, complex liquids (crude oil, blood, etc.), ice and biofilms, good compression stability, and self-repairing. It has become a major research field of new materials in recent years. hot spot. The self-lubricating surface of biomimetic Nepenthes can reach molecular level smoothness, which can significantly reduce the sliding angle and hysteresis angle of droplets, and can effectively inhibit the adhesion of various substrates including grease, blood, ice and biofilm. It is used in self-cleaning coatings, It has broad application prospects in marine antifouling, promotion of droplet condensati...
