Using NMR spectroscopy and NMR imaging, the behaviour of polymers in supercritical CO2 (sc-CO2) using a custom-made cell designed from poly(ether ether ketone) (PEEK) has been observed. The mechanism of swelling of polymers in sc-CO2 and the overall effects of sc-CO2 on the transport properties of both small and large molecules has been studied. We report on the swelling characteristics of radi...

In order to broaden the application range, PEEK has been modified by 1064nm-wavelength pulse laser, then deposited with Ni-P alloys electroless plating. The properties of metal layers on were characterized SEM, resistance tester and metallographic microscope, respectively. When laser energy density is relatively low (Q<60J·cm -2 ), there mainly photothermal effect surface substrate presents ...
