Is there any PDMS's surface modification methods for high temperature(250c)?

Uhyeon Kim @Uhyeon-Kim

13 February 2024 0 5K Report

I'm looking for surface modification of PDMS for 250c.

especially, reducing van der waals force between PDMS and silicon(or glass) substrate at 250c.

Is there any mothod?

thanks
