An ultra-thin, flexible proton-conducting (PEI-PCGF)/phosphosilicate/(PEI-PCGF) (PPP) membrane with organic/inorganic multilayer structure is prepared. The total thickness of the membrane is ca. 500nm. In the multilayer structure, the brittle inorganic phosphosilicate layer was supported and protected by organic PEI-PCGF layers, which provide sufficient mechanical strength and flexibility. The proton...
An integrated, crack-free glass monolith is prepared via a modified sol–gel approach. It has an accessible network of channels consisting of anisotropic pores of widths ca. 20–50nm and lengths ca. 100–250nm. The glass monolith exhibits a transparency change based on humidity, which is utilized as a basis for optical humidity measurements. On the other hand, the glass monolith shows high proton conduction...
