Nanocomposite Thin Film Sensors


25 years experience in all chain necessary for sensor developments: compound modeling, design and synthesis, thermal, electron gun, laser, plasma, CVD and combinations of that technologies in one run for production of nano-composite films, film characterization in situ by optical spectroscopy, AFM, TEM, modeling of nano-composite properties, sensor arrays design, optical and electrical properties measurements, software design.

  1. Waveguide optical sensor and electrical one.
  2. Deposition technologies for Teflon (PTFE), polyparaphenylene sulfide (PPS) and Parylene films.
  3. Metal(oxide)-dye-polymer nanocomposite films. Materials and deposition technologies.
  4. Synthesis of new evaporable dyes.
  5. Multi-layered systems.
  6. Tests for organic and inorganic agents including toxic analytes in real probes.

Innovative Aspect and Main Advantages

The integrated both optical and electrical sensor arrays based on the nano-structured thin films. Most robust insoluble polymers for aggressive environment. Dye synthesis taking into account deposition technology. No liquid during deposition of multi-layered systems. Combination of different kinds of materials in one nano-composite film with new properties. Easy production of gradient films. Standard base industrial vacuum equipment with mask deposition process. Sensor microchip arrays with several various sensitive dopants.

Areas of Application

Optical and electrical sensors based on most stable and inert polymers will be used for environment monitoring including hazardous processes in industry:

  • Control of pollutant level of organics and toxic impurity in environment;
  • Food and beverages quality control;
  • Revealing of the sources of pollutions;
  • Molecular recognition of complex gas mixtures in the “electronic nose” type instrument.

PTFE films filled with metal and dye nanoclusters can find applications in chemical catalysis, biochips, optical and photonics devices. PTFE, PPX and PPS can be used in waveguide as materials with low and high refractive indices. Filled with selectively sensitive compounds polymer waveguides are able to execute active functions in integrated optic and electric sensor devices.

We consider our developments as ready for presentation for farther development of technologies and installations on industrial level.
