An adjacent design validation question on a green chip factory and product design:
Will Phytic acid in Lignin-Vitrimer encase burning CNT carbon nanotubes in a phosphorous char cage, this preventing health hazards and combustion?
This says "phosphorous epoxy".
FR4 silicon PCBs are N-doped and P-doped.
Will the phosphorous in said epoxy also encase CNTs if there is combustion?
> The hypothesis in your text is chemically sound. The phosphorus [(polyphosphonates)] in the EMPA epoxy functions as an "intumescent" or char-promoting agent.
