In the hydrophobic technical field of microfabrication lifting workpieces.
Background technique
Hydrophobic surface is because having automatically cleaning, drag reduction and the performances such as wear-resistant, in the fields such as liquid conveying, building, ship, clothes
There are boundless application prospect, the large-scale industrial application of hydrophobic surface, it will convenience is brought to people's production and living,
Very big power is created for human development.For example, most common pan of cooking in people's life, often does after meal, edible oil is all
Meeting legacy part is in pot.This causes very big difficulty to cleaning, and people is forced to clean using dish washing liquid.And dish washing liquid contains
There are many surfactants, these substances enter after body, intracorporal eubolism can be interfered, usually often in contact with dish washing liquid
People, the incidence of colorectal cancer is very high；Some businessmans do not allow perishable to guarantee dish washing liquid, can add formaldehyde as anti-corrosion yet
Agent, although eating a small amount of formaldehyde not will cause acute poisoning, long-time service just will appear severe stomachache, vomiting and stupor etc.
Symptom.If hydrophobic surface is applied to the bottom of a pan, this hidden danger can be solved using its oleophobic property, remove people easily
The bottom of a pan surface and oil contaminant.
Research shows that micrometer structure, the multiple-rank arrangement and low-surface-energy material collective effect of nanostructure composition can make material
There is hydrophobicity on material surface.And the method for having production hydrophobic surface includes chemical method, special process method, all there is larger limitation.
Although chemical method has high-efficient, easy realization, can obtain the micro-architecture surface of nanoscale, and may be implemented extensive
The advantages of production, but its surface shape be difficult to control, surface alignment it is difficult to predict, it is difficult to realize microstructure design；And it is extraordinary
The defects of it can only be metal that processing method, which then has rapidoprint, and process equipment is expensive, and machining accuracy is limited.And both are processed
Method all leaving there may be harmful chemical element, if being applied to pan bottom or living closely related production with people
Product, it will subtle harm is caused to human body.
