Abstract: Disclosed herein are composite materials and methods for forming the same. In one embodiment, a composite material comprises a primer layer comprising a polyalkylenimine, and an active layer comprising a binder and a metal organic framework (MOF), wherein the MOF comprises a bidentate organic compound coordinated to a metal ion, and wherein the active layer forms a coating on the primer layer.

Abstract: The invention relates to a process for manufacturing a multilayered porous transport layer, the process comprising (a) providing a first feedstock comprising first metal particles and a first polymer binder; and providing a second feedstock comprising second metal particles and a second polymer binder; the first and the second feedstock having a metal powder content of 40 to 70% by volume; and the first feedstock having (i) metal particles with a smaller average particles size, (ii) a higher metal powder content, or (iii) both, metal particles with a smaller average particles size and a higher metal powder content compared to the second feedstock; (b) coextruding the first and the second feedstock to form a film-shaped green body comprising a first layer and a second layer, the second layer being materially connected to the first layer above the melting temperature and or glass transition temperature of the first polymer binder and the second polymer binder; (c) optionally smoothening the film-shaped green body by rolling or calendering; (d) debinding the film-shaped green body to form a brown body; (e) sintering the brown body under a non-oxidative atmosphere or vacuum and a temperature of from 700 to 1300° C. to form the porous transport layer; wherein the first feedstock and the second feedstock are free of any solvents.
