Double layer humidity sensor based on phthalocyanine derivatives
Rakušan, J. ; Karásková, M. ; Hamáček, A. ; Řeboun, J. ; Kubáč, L. ; Černý, J. ; Rais, David ; Nešpůrek, Stanislav
New type of humidity sensors based on double layer structure consisting of hydrophilic and hydrophobic phthalocyanine derivatives is presented. The sensor shows high sensitivity in the range from 20 to 90 % relative humidity (RH), good long-time stability and fast response. The impedance change vs. RH is quasi-linear in semilogarithmic plot and fully reversible.
Humidity sensor based on TiO2 nanoparticles and sodium salt of sulfonated AlOH phthalocyanine
Rakušan, J. ; Karásková, M. ; Hamáček, A. ; Řeboun, J. ; Rais, David ; Nešpůrek, Stanislav
New type of humidity sensor based on TiO2 nanoparticles and sodium salt of sulfonated AlOH phthalocyanine is presented. The sensor shows high sensitivity due to the high surface area of TiO2 nanoparticles, good long-time stability and sensitivity in the range from 20 to 80 % RH. The response is linear in semilogarithmic plot – logarithm of impedance vs. RH and fully reversible.

Evaluation of properties of pyrolysed resins
Halasová, M. ; Chlup, Zdeněk ; Strachota, Adam ; Černý, Martin ; Dlouhý, Ivo
The presented work describes mechanical properties of materials prepared by pyrolysis of polysiloxane resins. The polymeric precursors had different chemical composition. Materials under investigation are predetermined as a matrix for high temperature resistant long fibre composites. An instrumented hardness tester was employed for materials characterisation. The Vickers hardness, Martens hardness and indentation elastic modulus were the key parameters determined from the load-indentation depth curves. Influence of the mechanical properties on the ratio of T and D was established. Indents were observed by using confocal laser microscope.
