Microporosity in the single-lamellar crystals of natural clinoptilolite is organized in a very unique manner; indeed, it involves only the lateral surfaces of the crystals and not the basal planes. In particular, the channels form a two-dimensional array, which is placed in parallel to the crystal basal planes. In this two-dimensional array, A (0.72-0.44 nm) and B (8-member ring, 0.41-0.47 nm) channels are parallel each other, while C (8-member ring, 0.55-0.40 nm) channels are located perpendicularly to them. Such unique characteristics of clinoptilolite microporosity allows these 40nm thick single-lamellar crystals to be easily placed on a planar support (paper foil, polymer film, etc.) without occluding the microporosity and thus allowing mechanisms of molecular release or absorption to take place ^[1]. In addition, since the basal planes of clinoptilolite crystals do not contain any porosity, a binder can be placed at substrate-lamellas interface in order to stably connect them to the substrate without influencing the material microporosity.
