- TL;DR Summary
- I would like to prototype building my own enthalpy wheel (https://en.wikipedia.org/wiki/Thermal_wheel) and I need to apply some desiccant to the surface of the material that I will be making the wheel out of. How can I do this?
I will either be using aluminum strips wound up, or 3d printing it out of PLA or PETG. How can I apply a coating of silica to the surface of either of these materials so that it can hold and release the moisture of the incoming air/outgoing air?
This is to manage heat and humidity in my campervan project.
Ideally It would be easiest to 3d print the wheel, and PETG has much better thermal conductivity than PLA plastic, but both are significantly lower than aluminum.
