Wheat B-starch based polymeric materials
Kotek, Jiří; Kruliš, Zdeněk; Šárka, E.
2011 - anglický
The contribution is aimed at preparation of a thermoplastic material derived from the wheat B-starch. Two ways have been followed, namely blending of the starch with poly(ε-caprolactone) (PCL) and plasticizing of the starch. In both cases, properties of the materials based on the B-starch are comparable to analogous materials based on the A-starch. The prepared materials have potential application as biodegradable films for agriculture.

Hybrid structures based on montmorillonite/modified starch intercalate
Duchek, P.; Špírková, Milena
2010 - anglický
Intercalates based on several commercial cationized starches with degree of substitution D=0.04-0.17, and sodium montmorillonite were prepared. The XRD analyses of resulting organic/inorganic hybrids proved that modification in the starch structure leads to embedding the polycation into montmorillonite clay gallery. Lower degree of starch cationization results in bigger enlargement of the interlayer space in the hybrid structure.

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
2010 - anglický
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.

Novel nanocomposite materials for power engineering
Boček, J.; Matějka, Libor; Mentlík, V.
2010 - anglický
The epoxy-POSS nanocomposites were prepared and their electrical/dielectric and thermomechanical properties were determined. The mono- and octa-epoxyfunctionalized POSS (POSS,E1 and POSS,E8) were covalently incorporated in the epoxy network matrix DGEBA- 3,3’-dimethyl-4,4’-diaminocyclohexylmethane (Laromin C260) as pendant units or as polyhedral junctions, respectively. While the POSS junctions are well dispersed in the hybrid network DGEBA-Laromin-POSS,E8, the pendant POSS aggregate to form large crystalline POSS domains.

Cation and anion exchangers from nanofibrous polystyrene for fast water treatment
Marek, J.; Beneš, Milan J.; Jelínek, L.
2009 - anglický
Strongly acidic sulfonovaný cation exchanger on polystyrene nanofibrous matrix (Nanospider TM technology) was prepared by simultaneous sulfonation and crosslinking. Weakly basic nanofibrous anion exchanger was prepared after transformation of sulfogroups to sulfochloride by reaction with ethylene diamine. Nanofibrous products were characterized by sorption capacity. They have sorption kinetic significantly faster in comparison with standard granular ion exchangers. Současnou sulfonací a síťováním byl připraven silně kyselý sulfonový katex na polystyrenové nanovláknité matrici (Nanospider TM technologie). Slabě bázický anex byl připraven po převedení sulfoskupin na sulfochlorid reakci s ethylen diaminem. Nanovláknité produkty byly charakterizovány pomocí sorpční kapacity. Mají kinetiku sorpce výrazně rychlejší než standardní sorbenty granulární.
