    The influence of the nanofiller on thermal properties of thermoplastic polyurethane elastomers

  • Popis výsledku v původním jazyce

    Hybrid materials based on renewable resources are under huge interest of scientist nowadays. Polymer-based hybrid materials with the addition of nanoparticles are very interesting because the addition of small amount of nanoparticles significantly improves final material&apos;s properties. Group of polymers which is suitable for use for hybrid materials preparation are polyurethanes. Polyurethanes have wide spectra of commercial and industrial applications, but for their production petroleum-based derivative is used and big efforts are still making for changing it with components from renewable resources. Thermoplastic polyurethanes were synthesized using two types of isocyanates: isophorone diisocyanate and hexamethylene diisocyanate, and the possibility of using isosorbide, instead of butanediol, as chain extender for the synthesis of thermoplastic polyurethane elastomers was investigated. NCO/OH ratio was 1.15/1 and soft segment content 50% in all samples. Also, the influence of the addition of hydrophilic and hydrophobic silicon(IV)-oxide nanoparticles, in amounts of 0.5,1, 2, and 5%, on thermal properties of the obtained green polyurethanes is determined using DSC and TG analysis. It is shown that hydrophilic silicon(IV)-oxide nanoparticles have an influence on thermal properties of soft segment in polyurethane structure, while hydrophobic ones have the influence on hard polyurethane&apos;s segment properties, increasing Tg values. Thermal stability of polyurethanes increased with increasing the amount of nanoparticles added. FT-IR analysis showed that there is no chemical reaction between polymer and nanoparticles.
