Description
Technical field
The present invention relates to chemical, machining, function interface, heat transfer research field, particularly a kind of anti-condensation anti-freeze surface, its preparation method and application thereof.
Background technology
Ice in surperficial formation by seriously hindering the normal operation of equipment, as electric wire, air-conditioning, refrigerator, road surface, aircrafts etc., have caused very large economy consumption and personnel injury.In China, there is every year the defrost of 300,000,000,000 degree electricity for refrigerator and air-conditioning, account for 6% of national power consumption.Therefore, effectively solving surperficial ice formation issues is current great matter of science and technology urgently to be resolved hurrily.
In the anti-freeze research in past, be mainly divided into two classes.One class is mainly to drop on super hydrophobic surface in cassie state around flood, and heat-transfer effect is poor, and the contact area of Cheng Binghou and solid is little, plays to delay flood and drop in surperficial freezing time and reduce the effect that ice adheres to.But under condensation exists, the performance on super-hydrophobic anti-freeze surface can reduce greatly, has even strengthened ice adhesion thereon.Another kind of is the rough surface containing hydrophobic oil reservoir of constructing rising for nearly 2 years, utilizes the liquid liquid sliding force between profit, thereby water droplet easily delays to freeze from surperficial landing realization, and reduces ice adhesion thereon.But regrettably, this oil reservoir cannot remain in coarse structure for a long time, oil reservoir runs off and causes environmental pollution, and deicing properties reduces greatly.
At occurring in nature, along with temperature reduces, steam is inevitable at surface condensation.And condensing drip size is far smaller than capillary length, even on typical super hydrophobic surface, also cannot rely on gravity to tumble from surface.Once these small condensed waters freeze on surface, these ice that are pre-existing in will be induced follow-up water, as sleet, are carved into ice on surface, and the performance that has seriously hindered anti-freeze material, has increased ice adhesion from the teeth outwards greatly.Therefore in the research of anti-freeze material, prevent that condensed water from freezing on surface is the most important thing.
The research of antagonism condensed water low-temperature surface is at present little, and Aisenberg utilizes the rough surface of oil-bearing layer to make condensing drip from surperficial landing [Kim, P.; Wong, T.-S.; Alvarenga, J.; Kreder, M.J.; Adorno-Martinez, W.E.;Aizenberg,J.,Liquid-Infused Nanostructured Surfaces with ExtremeAnti-Ice and Anti-Frost Performance.ACS Nano2012,6,6569-6577]。But this method, oil reservoir is unstable, easily volatilization, contaminated environment and repeat performance are poor.The more important thing is, minimum water droplet that can landing also will reach hundreds of microns, and as 600 microns, in the time that temperature is lower, condensing drip is enough to make it to solidify from nucleation to the time that grows to hundreds of microns.Therefore, realize many, as far as possible little as far as possible condensing drips and depart from the key that is only the anti-freeze surface of anti-condensed water from surface, increase substantially the performance on anti-freeze surface.
On some super hydrophobic surface, the surface discharging after condensing drip merges can make it that jump outside face occurs.And the size that this merging is jumped can be as small as several to tens microns.Make full use of at low temperatures condensing drip and merge the characteristic of jumping, promote condensing drip before freezing, to depart from surface, low-temperature surface remains that under condensing condition " being dried " state is the object that we prepare this anti-freeze surface of anti-condensed water.
By introduce micron hole at nanoscale rough surface, thereby the contact area reducing between condensing drip and surface has reduced the adhesion between water droplet and surface.The surface discharging after condensing drip merges can more easily overcome the adhesion of substrate to it, and easily jumps out of from surface.It is less that the method makes merging jump out of surperficial water droplet size, and frequency is higher, thereby reaches better anti-freeze effect.
