Polymer Coatings Based on Polyisobutylene, Polystyrene and Poly(styrene-block-isobutylene-block-styrene) for Effective Protection of MXenes

MXene films with a conductivity of about 4000 S/cm were obtained on glass substrates following drop-casting method and characterized by scanning electron microscopy (SEM), X-ray diffraction analysis (XRD) Raman spectroscopy. The polymer coatings polystyrene (PSt), polyisobutylene (PIB) tri-block copolymer styrene (SIBS) deposited their efficiency toward the protection MXenes against oxidative degradation was estimated at ambient conditions. A loss detected for PSt-coated after 220 days storage, while pristine stored 400 conductive resistivity increased 2.5 times. Nonpolar based isobutylene showed ability to protect from oxidation during long-term period. After coated PIB SIBS 1.8 1.4 times, respectively. results are interest expanding industrial application films, increasing operation simple coating nonpolar flexible polymers.
