Making nonpermanent hydrophilic surface

[Simonas]

Hello everyone,
i am looking for information on relatively simple ways to make a glass surface (microscope slide) hydrophilic, so a water film on this glass sample can be made as thin as possible (100 - 500 um). It does not have to be permanent, so perhaps someone can recommend some easily obtainable chemicals (if there are any) that would perform such a task by covering the sample with them. Complicated coating techniques are not favourable in such a practice.
Much thanks.

Welcome to PF;
Hmmm ... I suppose you could try to make it positive charged and coat it with an insulator (varnish?)
... rub the glass with ethanol? That would be very temporary, and smeary too.
Can't think of a good way to do it easily.

As far, as I know, glass has perfect wettability by water(week liquid on a strong solid). So, all you need is to clean it, especially from grease(week surface)

use RainX Anti Fog or make your own with this.

Hi there,

There are a few different methods you could try to make a glass surface hydrophilic. One option is to use a surfactant, such as soap or detergent, to reduce the surface tension of water and allow it to spread more easily on the glass surface. Another option is to use a plasma treatment, where the glass surface is exposed to a high-energy gas to modify its surface properties. This can be done using a plasma cleaner or even a microwave oven.

Another method is to use a chemical coating, such as a silane or titanium dioxide, which can be applied to the glass surface to make it more hydrophilic. These coatings can be easily obtained from chemical suppliers and can be applied using simple techniques such as dip coating or spray coating.

It's important to note that the hydrophilicity of the surface may decrease over time, so it may not be a permanent solution. However, with regular cleaning and maintenance, you should be able to maintain a hydrophilic surface for your experiments.

I hope this helps and good luck with your research!
