20.500.12556/RUL-139765 Vpliv razmerja zamreževalca in temperature zamreževanja na mehanske lastnosti polidimetilsiloksana Effect of curing agent ratio and curing temperature on mechanical properties of PolyDiMethylSiloxane V sklopu diplomskega dela smo obravnavali vpliv razmerja zamreževalca in temperature zamreževanja na mehanske lastnosti polidimetiksiloksana. Material smo testirali s termično in reološko analizo, preko nanoindentacije pa smo določili mehanske lastnosti. Rezultati so pokazali, da se mehanske lastnosti zamreženega polidimetilsiloksana z naraščanjem temperature bistveno ne spreminjajo, medtem ko temperatura močno pospeši čas zamreževanja. Po drugi strani pa razmerje zamreževalca močno vpliva na mehanske lastnosti zamreženega polimera, pri čemer se elastični modul ne-monotono spreminja in doseže vrh pri razmerju 10:1. Within the scope of thesis, we studied the influence of the curing agent ratio and the curing temperature on the mechanical properties of polydimethylesiloxane. The study was conducted with thermal and rheological analysis. Moreover, the mechanical properties were measured with nanoindentation. The results showed that mechanical properties of polydimethylsiloxane do not change significantly with increasing curing temperature. However, temperature significantly reduces curing time. On the other hand, the crosslinking ratio has a profound effect on the mechanical properties, where elastic modulus exhibits nonmonotonical behavior with peak at 10:1. polidimetilsiloksan vpliv temperature vpliv razmerja zamreževalca kinetika zamreževanja mehanske lastnosti polydimethylsiloxane effect of temperature effect of curing agent ratio kinetics of curing mechanical properties true false false [A.
