Abstract
High-quality TMA-A zeolite nonocrystals were synthesized using a hydrothermal method from a Al(i-pro)(3) : 2.2 TEOS : 2.4 TMAOH : 0.3 NaOH : 200H(2)O composition. The average size of the zeolite crystal used was 60-130 nm with a lattice constant of 12.389 angstrom. The well-oriented self-assembled monolayers of zeolite with a face parallel to the glass surface treated with the 4-diisocyanates (DIC-4) showed only planes of the form of {h 0 0} by covalent linkages. High resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and dynamic light scattering (DLS) were used to characterize the self-assembled monolayers of synthesized zeolite crystals.
