Organic materials have been widely used in Membrane industry because of their lightness, flexibility and diversity of molecular designs.
The expansion of organic thin film methods, in addition to vaccum deposition drying processes among others, is reaching wet printing processes as well.
Our research focuses on transforming organic materials into thin films to be applied in electroluminescence devices, solar cells, sensors, etc.
With this background, we perform research on the following subjects.

Development of a Novel Manufacture process for Nano-structure Controlled Organic Thin Membrane
In our group, we carry on research on novel membrane formation technologies oriented to printable electronics such as: photocontact printing methods, uniaxial-oriented organic semiconductive crystal wire, crystal growth processes performed in ionic solutions etc.
Additionally, in dry processes, we are performing research on measurement of substance steam pressure as an important parameter of thin film growth by application of vaccum evaporation method, and, tetramerization reaction of gas-solid interface obtained through chemical vapor deposition.
Development of an Organic Ferroelectric VDF Thin Membrane Oriented to Application in Sensing-Energy conservation
In Vinylidene fluoride group (-CH2CF2), there is a big vertical dipole in molecules axis from hydrogen and fluorine's electronegativity diference.
Our research aims to obtain highly efficient ferroelectricity, pyroelectricity and piezoelectricity in oscillatory-electric elements, piezoelectric sensors (contact, flexed) infrared-thermosensors (human presence sensors - gas sensors) and organic non-volatile memories by controlling membrane structure and molecule orietation in organic materials such as VDF-related materials, Polyurea, TGS etc.
