Example 1
In a glovebox operating under argon atmosphere, 2.4 g of lithium sulfide glass (Li2S:P2S5=75:25) was placed in a cup. 1.04 g of PFPE dimethacrylate (Fluorolink MD 700, Solvay) was added, followed by 0.051 g of benzoyl peroxide and 7.3 g of dry Fluorinert 70. The cup was placed in a Thinky mixer (Thinky ARV-SOLED) and mixed at 1500 rpm for 40 mins. The slurry was cast on aluminum foil using a doctor blade. The film was dried on the coater, while maintaining the vacuum, then was transferred to an antechamber and dried under vacuum at 60° C. The dried film was scraped off and the material was pressed into pellets under 120 MPa, using hydraulic press, and then heated at 125° C. for two hours. After that, the heating was removed, the pellet was cooled to room temperature and only then the pressure was released.
