DESCRIPTION OF THE PROJECT

The „Thin Film of Nanoporous Silica Zeolite Crystals on Ceramics for Low-Dielectric Constant Materials” Bilateral Project, financed through CAPACITIES Programs, Module III, bilateral cooperation carried out in collaboration with the University of HANSEO, South Korea proposes the development and manufacture of ceramic thin films of nanoporoase zeolites crystal silicon on glass and ceramic substrate materials with low dielectric constant. A nonoporous silica zeolite thin film which is one of the decisive candidate materials for future generation low-dielectric constant materials. A lower dielectric constant materials can reduce resistance capacitance (RC) delay, power dissipation, and interline crosslink. Organization of nanometer-sized zeolite crystals into uniformly oriented monolayers on various supports by hydrothermal method is of great interest for various reasons. For instance, it is an effective way to produce zeolite thin film that can be widely applied in industry as thin-film catalysts, nano-porous sieves for molecular separation, size-selective sensing devices. The oriented monolayers thin film of zeolite crystals have also great potential as ideal media for organization of semi-conductor quantum dots and nonlinear optical molecules, and as well-defined nanoreactors for exploration of novel chemistries in highly confined and organized environments.

PARTENERS

Korean partner – Hanseo University, one of the most experienced institute in the field -contributed with basically and technical characteristic analysis by using Environmental Scanning Electron Microscopy (ESEM), High Resolution Transmission Electron Microscopy (HRTEM), X-ray powder diffraction (XRD), Fourier Transform Infrared (FT-IR) spectroscopy, DTA/TGA and BET analysis, not fully available in Romania.

Romanian partner – The "Gheorghe Asachi" Technical University of Iasi, the most important department of advanced dielectric analysis in Romania - investigated the dielectric constant of the orientation-controlled monolayer assembly of zeolite nanocrystals on glass and ceramic substrates by covalent linkages. The used dielectric methods were: broadband dielectric spectroscopy up to 10 GHz and up to 450 C, pulse electroacoustic analysis, broadband partial discharges analysis and thermally simulated currents method, methods not fully available in Korea.
