A study of Parylene coated Pd/Mg nanoblabes for reversible hydrogen storage

► Ultrathin Parylene can be conformally coated on Pd/Mg nanoblades. ► Parylene coated samples show reversible hydrogen storage property. ► Parylene coated samples show low desorption temperature (∼400 K). ► Slow-down kinetic of hydrogen desorption is explained by kinetic modeling.
