Research

The Laboratory of Advanced Polymers & Optimized Materials (LAPOM) Development of materials with improved mechanical, tribological and thermo-physical properties, including thermoplastics, thermosets, composites, nanohybrids and coatings. High strength, wide service temperature range, low thermal expansivity, low static and dynamic surface friction, high adhesion of coatings to ceramic and metal substrates, high scratch, wear and mar resistance.

The Electron Microscopy includes a Hitachi H-9000 high resolution transmission electron microscope, a JEOL 200CX analytical electron microscope, a JEOL 100CX analytical transmission electron microscope and a JOEL T-300 scanning electron microscope.

The Polymer Mechanical and Rheological Laboratory is engaged in investigations of interrelationships between morphology and mechanical properties through the influences of time and temperature of polymers, composites and hybrid organic-inorganic nanocomposites. A Mechanical Testing System (MTS810) equipped with an environmental chamber (-150° to 600° C), video and thermal wave imaging provide stress pattern-temperature relationships around propagating cracks and estimate residual stresses. A Torsional Rheometer provides visuelastic and rheological property evaluation. Reliability of dielectric property retention is being examined through simultaneous effects of radiation and electrical fields using thermally stimulated depolarization currents and thermoluminescence.

The Materials Synthesis and Processing Laboratory has research interests focused on the development of aerogels and other novel ceramics for dielectric, sensor and high temperature applications. A complete synthesis laboratory is available with several spin coaters for thin film development and with a BET surface area/pore size analyzer for structural characterization as well as high temperature furnaces and a critical point dryer.

The Display Materials Laboratory works on field emission displays based on field emission and cathodoluminescence. Display performance is currently restricted by several materials-related limitations. We are investigating these materials-related issues, including low work function materials, thin-film getters and novel spacer materials. We are also studying the reliability of organic light emitting materials and low permeability plastic substrates for flexible displays.

The Laboratory for Electronic Materials and Devices is a cross-disciplinary laboratory performing basic and applied research on novel materials for advanced electronic devices of all kinds.
