Smart Materials

Smart materials have properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields. There are many groups of smart materials, each exhibiting particular properties which can be harnessed in a variety of high-tech and everyday applications. These include shape memory alloys, piezoelectric materials, magneto-rheological and electro-rheological materials, magnetostrictive materials and chromic materials which change their colour in reaction to various stimuli. Nanoscale materials, PCM (phase change materials), advanced composites and smart polymers are other important modern day materials. Researchers at the TUL are very successful in developing new combinations of such materials for advanced applications. For their research they can use top-notch laboratories for testing various properties of textile materials.
 They can also use laboratories at the Institute for Nanomaterials, Advanced Technologies and  Innovation, which is abbreviated at the Technical University as CxI.

Nanocomposites Based on Advanced Fibres, such as Carbon and Basalt     Rajesh Mishra + team
The composites of fibres, matrix and nanoparticles combine natural  properties with the advanced ones: high-temperature resistance, chemical impedance and impact protection. Thus they are ideal to be used in protection of humans (bulletproof clothing, electromagnetic shielding), sensitive devices (moisture barrier) and buildings (seismic retrofit for improved earthquake performance).

Piezoelectricity and Ferroelectricity     Jiří Erhart
Piezoelectricity belongs to the main applied properties of polar dielectric (smart) materials. It is the direct conversion between mechanical and electrical fields. Lots of industrial applications exist, e. g. ultrasound generation and detection, sensors of force, pressure and acceleration, piezoelectric resonators, transducers and actuators, etc. Ferroelectric dipole moment arrangement in materials causes polarity of the structure and also piezoelectricity.

Unique Autocosmetics         Petr Louda + team
Prof. Petr Louda's team, together with the company PIKATEC designed and introduced into the market special car cosmetics of the second generation containing nanoparticles of metal oxides. It creates a very hard thin layer on the body of the car, which prevents scratches. Its composition makes it fully water-repellent and resistant to heat and UV radiation. The invention resulted from a project Innovative Products and Environmental Technology (ENVITECH) and it successfully transfers research into a commercial application. Read more.
