a Normalized Raman spectra of the NCMs (F, 1/1) and SPNCMs (F, 1/1). b XPS survey spectra of the F-APF resin (1/1), NCMs (F, 1/1), and SPNCMs (F, 1/1). High-resolution N 1s XPS spectra of c the F-APF resin (1/1), d NCMs (F, 1/1), e SPNCMs (F, 1/1). f N K edge XAFS spectrum of the SPNCMs (F, 1/1) (the test was performed in the total electron yield (TEY) mode).
