文摘
- •
The well-controlled Ti–PTFE composite films were prepared by co-sputtering.
- •
Ti clusters showed particle sizes varied between 10 and 30 nm in the PTFE matrix.
- •
The swelling of polymer is the driving force to change interparticle distance and therefore a change in resistance.
- •
The sensitivities of the Ti–PTFE devices were found to be in a range of 1.01–1.04.
