AbstractThe influence of microstructure on the properties of zeolite films and means of controlling the former (film thickness, crystal orientation) are the theme of this report. Firstly, the formation of thin silicalite films from regrowth of nanocrystalline silicalite/alumina composite films is presented. The crystallites at the intergrown top layer are oriented with their straight channels parallel to the substrate film. The membranes show H2/N2 selectivities of about 60 at 150 °C.This high selectivity is attributed to the orientation of the separating layer. Secondly, the formation of oriented multilayers of zeolite L crystallites by alternating dippjpg of a glass substrate in a bohemite and a “plate-like” zeolite L suspensions is illustrated. Finally, continuous films of zeolite NaA are prepared on various substrates (glass, porous and nonporous alumina) using in situ growth from homogeneous solutions. The films exhibit good adhesion to the substrates. The films prepared on porous alumina disks show He/N2 and O2/N2 selectivities of 10 and 0.4 respectively at 120 °C.

And Chemical Properties

Now there is a motivation for creation of the materials possessing a considerable difference of physical and chemical properties in volume of composite materials 1 . Composite materials allow realizing a complex of various properties which cannot be realized simultaneously in mono material. The perspective in reception of a new smart nanomaterial is basically defined by possibilities which create processing conditions Choosing and manufacturing of fibers refers to the second stage of composite material reinforcement. Process of assemblage of a composite material from the details made at first two stages of process refers to the third stage. But at each stage of process of manufacturing of a composite material there are specific problems. The basic problem at composite material creation, as a rule, is essential contradictions between engineering solutions for various stages of process.

We present a novel method of using Particle Image Velocimetry in electrospraying process studies. Electrospraying of metal oxides nanoparticles and covering nonwoven nanofiber mat creates composite material for potentially wide applications. Precise control of the electrospinning process gives possibility for better control of nanoparticles deposition and thereby enhancing its relative properties.
