So, I've seen some videos about laser induced graphene and its use as either a supercapacitor or as a low-voltage heater.
In this video the person only uses two electrodes on each end of the LIG tape to make such low-voltage heater. But one of the remarks he makes is that the heater will only work until the kapton tape fails due to its temperature.
So I was wondering if extracting the LIG from the Kapton tape, the graphene would still work. But I don't know how such thing would be achieved.
