Post Deposition

Electrophoretic deposition was investigated as a procedure for preparing supported membranes of zeolite 5A for use in gas separations. In particular, the addition of polyethylene imine (PEI) to the non-aqueous bath was explored as means of improving gas separation selectivity, deposit morphology, and adhesion. It was found that the addition of PEI improved all of these qualities. Post-deposition treatments such as baking and coating with polystyrene were also studied.

Gas Separation Performance

Polynorbornenes are already used in a wide range of applications. They are also considered materials for polymer gas separation membranes because of their favorable thermal and chemical resistance, rigid backbone and varied chemistry. In this study, the use of 5-vinyl-2-norbornene (VNB), a new monomer in the field of gas separations, is investigated by synthesizing two series of polymers via a vinyl-addition polymerization. The first series investigates the influence of the VNB content on gas separation in a series of homo and copolymers with norbornene. The second series explores the influence of the crosslinking of polyvinylnorbornene (pVNB) on gas separation. The results indicate that while crosslinking had little effect, the gas separation performance could be fine-tuned by controlling the VNB content. As such, this work demonstrates an interesting way to significantly extend the fine-tuning possibilities of polynorbornenes for gas separations.
