Hello,
I am looking at a castable/spinnable material to coat my microfluidic channels. It is fundamental that the coat is transparent and hydrophilic. Any suggestion?
Thank you!
How about the staple of organic LEDs/solar cells, PEDOT:PSS? Spin-coating from an aqueous dispersion yields very uniform and controlled (in terms of thickness) layers and the system shows very minor Vis-range absorption.
It depends on the longevity of the treatment!
I would normally use a plasma priming for a single time use devices, but if you are for some repeated uses, then HMDS coating is always a good way to promote surface chemistry.
Lastly the using Ormocers can offer alot towards more permanent solutions, but you would need to develop a process to ensure coverage in the fluidic system.
Hydrogels, glass, polymers, such as silicon (PDMS) can be the effective coating for microfluid channels with tunable hydrophilicity and transparency.
