Polymers are the most studied viscoelastic material. The shorter times (high frequencies) corresponding to lower temperatures and long times (low frequencies) to high temperatures. This represents the quantitatively applied time-temperature superposition (TTS). Use of the Williams- Landel-Ferry (WLF) equation and the time-temperature superposition principle enables prediction and modeling of the mechanical and rheological properties of polymeric systems outside the timescale of the experiment. Application and validity of the TTS principle and WLF equation in polymer blends, composites, biopolymers and polymer networks will be discussed in this review.
Polimeri su najproučavaniji viskoelastični materijali. Kraće vreme (odnosno visoke frekvencije) odgovaraju nižim temperaturama, a duže vreme (odnosno niske frekvencije) odgovaraju visokim temperaturama. Ovaj odnos vremena (frekvencije) i temperature predstavlja kvantitativnu primenu principa superponiranja vremena i temperature (TTS). Upotreba Viliams-Lendl-Feri (Williams- Landel-Ferry, WLF) jednačine i principa superponirnaja vremena i temperature omogućava predviđanje i modelovanje mehaničkih i reoloških svojstava polimernih sistema izvan vremenske skale eksperimenta. Upotreba i validnost TTS i WLF jednačine na polimerne blende, kompozite, biopolimere i polimerne mreže biće predstavljeni i razmatrani u ovom radu.
