Polymeer chemie – project pnipam
ORGANISCHE SYNTHESE 2 – PROJECT
Uitvoerende(n): Renée Beckmann
Docent: Rob Niekel
Datum Experiment: 29 jan 2021
Datum Rapportage: 16 juni 2021
SAMENVATTING 1 2
Het doel van dit experiment is het synthetiseren van een thermoreponsieve hydrogel door
middel van een radicaal polymerisatie reactie vanuit het monomeer NIPAM, ammonium
persulfaat (initiator), MBAA voor het vormen van de crosslinks en TMEDA als accelerator.
Er is een opbrengst gemeten van 2473% (24,98 gram). De analysetechniek IR en de
bepaling van het thermoreponsieve gedrag hebben de vorming van pNIPAM bevestigd.
1650-1580 N-H (amine) binding
3700-3000 O-H (water) binding
1700 C=O
Bij het thermoreponsieve gedrag is er een afname van rond de 40% te zien in oppervlak.
De conclusie die getrokken kan worden is dat er pNIPAM is geproduceerd.
