文摘

Zeolitic Imidazolate Framework-7 (ZIF7) films have been fabricated by a supersonic cold-spraying method. Crystalline structures of the supersonically sprayed ZIF7 film can be controlled by adjusting the nylon content. Supersonic spraying technique is versatile, it can be used to fabricate ZIF7 phase-I, -II, and -III. Inclusion of 6 wt% of nylon improves framework mechanical stability, preventing phase changes upon high-energy impact.
