| Description
| - Polymerní směsi jsou atraktivní materiály hlavně díky vhodnému poměru mezi cenou a nabízenými vlastnostmi jež je dán kombinací technických a komoditních polymerů. Na druhou stranu jejich produkce je limitována problémy vázajícími se s nemísitelností jednotlivých složek. V práci je studována možnost jejich kompatibilizace pomocí ultrasonického ozařování (elastické mechanické vlny o frekvenci 104-108 Hz) jako dalšího potencionálně možného způsobu odbourávajícího problém nemísitelnosti. Práce je zaměřena na studium účinku ozařování na fázovou strukturu a tokové chování směsí ve vztahu k jejich složení. (cs)
- Blends of high-density polyethylene (HDPE) and polyamide 6 (PA6) were produced by ultrasonic extrusion. Ultrasonic irradiation leads to degradation of polymers and in situ compatibilization of blends as confirmed by the variations of linear viscoelastic properties. The results showed that the effect of ultrasonic irradiation on dynamic rheological properties depends on the composition and experimental temperature. At the same time, the relationship between storage modulus and loss modulus quantifies the effect of ultrasonic irradiation on compatibility of HDPE/PA6 blends. Using emulsion model, the interfacial tension between the matrix and the dispersed phase was predicted. The obtained data showed that ultrasonic irradiation can decrease the interfacial tension, and thus enhance the compatibility of HDPE/PA6 blends.
