I want to prepare a thin film from PEG polymer, but I ask what is the best method to prepare it?
Thank you for your response, I would like to prepare PEG 6000 thin film.
easiest is spin coating
Langmuir Blodget film also can work
It all depends on the thickness you are interest in having and how homogeneous the film should be.
I agree with Prof Jhony Orbulesco, it depends on what thickness of the films. If thin film (below 2000 A), then spin coating or Alngmuir Blodget. If in the range hundred micron then solution casting.
Hello Karar Abdali,
How are you my friend, it is easy to use spin coating method to prepare the PEG thin film and the thickness could be optimised by controlling the speed and time of the spin coating as well as heat treatment of the film itself.#

spin coating may be an easy option for thin films. Are you also looking into the microstructure of the films, then you need to be more specific in the synthetic route.
Spin coating is certainly an option. You should use an attractive support to avoid dewetting. Overall if your PEG is low molecular weight.
I would recommend spin coating. You can make films of different thicknesses with minimal effort by controlling spin speed and/or the solution concentration. Poly(ethylene glycol) (PEG), otherwise known as poly(oxyethylene) or poly(ethylene oxide) (PEO) is water soluble. Therefore you can coat it only on hydrophillic substrate such as glass or SiO2 coated silicon.
You may please look at the following ref. for some details.

Hello, my brother Dr. Burak Kadem, how do you do, thank you for your answer and I wish to you the best.
