Preparation and Study of Polysiloxane Hydrogen Getter Film
Hydrogen getter material was prepared by physically blending polysiloxane resin and powered DEB-Pd/C. Homemade devices were used to evaluate the H2 adsorption ability of different materials obtained. SEM measurements were carried out to characterize the scattered powder in the polymer matrix. The study shows that, compared with powered DEB-Pd/C, polysiloxane hydrogen getter prepared here reacts slower with H2, it could achieve 90% percent hydrogen. Density of the sample significantly affects its reaction rate with H2, sample with lower density reacts faster with H2.
