Hello,
I am working on developing a thin film for solar steam evaporation.
Reference paper: Article Super-hydrophilic copper sulfide films as light absorbers fo...
In these papers, the common technique used to deposit the nanoparticles onto the substrate, to form the film, is vacuum filtration.
In my current lab I do not have a standard vacuum filtration set up available and I was planning on purchasing a pump to use for this purpose.
Given the high costs of a typical vacuum pump, I intended on purchasing a hand held vacuum pressure pump (picture attached, video: https://youtu.be/VHAURJD7X7M) which can achieve a maximum vacuum pressure of 4PSI/0.3bar.
Would this be sufficient for good deposition of the nanoparticles onto the substrate to obtain a good quality thin film that could be used for the purpose of solar steam evaporation?
Thank you for your help.
(I do not own the pictures I have attached)
Dear Joshua Nigel Fernandes , if you are planning to use that vacuum filtration setup, probably it would be more useful to buy a water jet vacuum pump. They are affordable, can be installed in any lab faucet and probably their main drawback is that they use running water to work and they don´t produce a strong vacuum.
Please, have a look to the following links or make your own search:

Having a vacuum line or/and a vacuum pump is often very useful in any lab. You might also ask to some other lab to use their own vacuum system.
Hope it helps.
