oil-impregnated hydrocarbon-based polymer films  -  film packaging material
The porous surfaces soaked with liquid lubricants exhibit a minimum contact angle lag with the test liquids that are not mixed, making them self-contained
Cleaning materials.
A more and more popular option is to use an absorbent polymer as a "porous" material rather than crude the solid substrate.
So far, however, the choice of polymer is limited to expensive silicone-
Complex components based on polymer or polymer multilayer film on the menu surface.
In this paper, we show that hydrocarbons
Polymer films such as polyethylene can be stably soaked with chemical-compatible vegetable oil without any surface treatment. These oil-
Dipping hydrocarbons-
For a variety of test products including water, tomato sauce, and yogurt, the film-based exhibits minimal contact angle lag. Our oil-
Even after a few weeks of soaking in tomato sauce, the dipping film is still slippery, indicating their extreme durability.
We expect simplicity and cost
Effective properties of our smooth hydrocarbons
Industrial packaging applications based on film will make it useful. Liquid slide-
Injected into a porous surface (SLIPS)
Excellent performance on display
Low angle lag (CAH)
Excellent self for a variety of liquids
Healing ability and stability at high pressure or high temperature.
In addition to repelling liquids, it has been demonstrated that Kava can promote-fouling, self-cleaning, anti-
Freezing, reducing resistance and enhancing phase-
Heat transfer.
Two main criteria must be met in order to ensure stable sliding :(1)
There must be nano/Micron on the surface
The roughness of holding the lubricant in the appropriate position by capillary action, and (2)
The chemical affinity of the substrate to the lubricant must be greater than the working fluid it repels.
The substrate can be either a rough and/or porous non-permeable material or a "nano-
"Roughness" is the molecular matrix itself.
The absorbent polymer coating is becoming more and more popular because of its compatibility with various industrial metals and practical materials.
So far, however, the choice of polymers is limited to expensive silica gel or fluorine-
Complex Assembly based on polymer and/or involving multi-polymer
Polymer coating on the menu surface.
And a class of cross-
The linked elastic body, known as organic gel or fluorescent gel, can be expanded with oil, which is actually limited by similar problems such as cost and complexity.
The inside of the organic gel has also been cured with oil, but this method needs to change the environment (
Heat or pressure)
Release the oil to the surface. Hydrocarbon-
Polyethylene and other polymer (PE)
And polypropylene (PP)
In terms of production volume, it is the most common plastic in the world and is widely used for packaging applications due to its cost-effectiveness and chemical resistance.
Although the extrusion film packaging is directly converted into slides to maximize the obvious attraction of the product's drainage, this has not been considered so far because of hydrocarbons-
Base films such as PE are generally considered oil-resistant and dipping.
In fact, PE is even used as a liner material for kava because of its excellent chemical and moisture-proof properties.
When the oil is immersed in the PP micro-pore film, the oil is immersed in the micro-pore film instead of the PP itself.
Before the invention of kava, there was already a technology for mixing super-melting solutions.
High molecular weight (UHMW)
Polyethylene with oil, usually used as a rolling bearing.
However, these are fundamentally different from mistakes in two important aspects.
First of all, this method requires that the oil be mixed with the molten polymer before curing, and for the cava, the lubricant is simply evil and has
Solid substrate.
Second, the oil cured in the polymer using the melting method cannot be freely migrated to the outer surface unless it is subjected to strong forces such as the centrifugal force experienced by the bearing.
This is in sharp contrast to the soaked kava liquid, which can passively suck the core to the outer surface to supplement any lubricant that has been exhausted over time.
Again, Golovin.
Hydrocarbons are reported
An oil-based polymer to adjust the mechanical properties of the polymer and minimize ice adhesion.
In short, so far there is no proof of the use of hydrocarbons
As a polymer of kava.
Here we present a surprising discovery of several squeezed hydrocarbons
Polymer films such as polyethylene can be directly and stably soaked with lubricating oil to convert them into carwa.
By utilizing low-density polymers such as ultra-
Low density polyethylene (ULDPE)
, Used with vegetable oil with excellent chemical compatibility with polymer films.
When oil enters hydrocarbons,
The polymer-based speed is really very slow, and we have shown that there is no problem with this in the case of dipping micron thin film layers.
Finally, we show our hydrocarbons.
Newton fluid can be repelled permanently based on sliding (water)and non-
