20.500.12556/DKUM-56026 Ring opening metathesis polymerisation (ROMP) as a tool for polyhipes with extraordinary mechanical properties PolyHIPE materials have been prepared by Ring Opening Metathesis Polymerisation (ROMP) of dicyclopentadiene. Two characteristic features for successful stabilization of high internal phase emulsions (HIPEs) were tuned in order to achieve improvements regarding mechanical properties of polyHIPEs.Mechanical properties of the new materials were related to variations of the surfactant concentration and the volume ratio of the internal phase in HIPEs. Values for Youngʼs moduli were about a hundred times higher than in standard polyHIPE materials with the same level of porosity, which represents a major improvement for highly porous cellular polymeric materials. Moreover, fully interconnected macroporous morphology was found forpolyHIPEs, where respective HIPEs were stabilized with only 0.25 v% of surfactant. Za pripravo poliHIPE materialov smo uporabili polimerizacijo pri kateri smo polimerizirali ciklične monomerje (diciklopentadien) z metodo odpiranjem obroča (ROMP). PoliHIPE materiali polimerizirani s ROMP mehanizmom so se iz- kazali z izjemnimi mehanskimi lastnostmi, saj so meritve mehanske jakosti pokazale sto krat višje vrednosti v primerjavi s poliHIPE materiali polimeriziranimi z navadno radikalsko polimerizacijo. ROMP v kombinaciji s HIPE templatiranjem se je izkazal kot izredno dobra kombinacija za proizvodnjo visoko poroznih polimernih materialov z izjemnimi mehanskimi lastnostmi. emulsion templating ring opening metathesis polymerization dicyclopentadiene ROMP mechanical characteristics polyHIPEs polimerizacija ROMP diciklopentadien mehanske lastnosti poliHIPEs true false true Angleški jezik Slovenski jezik Znanstveno delo 2015-12-21 16:17:04 2015-12-21 16:17:04 2022-06-10 03:09:29 2022-03-30 03:08:39 2013 0 0 str. 448-454 št. 2 Letn. 60 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 661.715.5 14086149 17050902 1318-0207 URN:SI:UM:DK:YWDTUNZG Acta_Chimica_Slovenica_2013_Kovacic_Ring_opening_metathesis_polymerisation_(ROMP)_as_a_tool_for_polyHIPEs_with_extraordinary_mechanical.pdf Acta_Chimica_Slovenica_2013_Kovacic_Ring_opening_metathesis_polymerisation_(ROMP)_as_a_tool_for_polyHIPEs_with_extraordinary_mechanical.pdf 1 4F469F05640F3F4A3CF0C7EA2BAB033A ff1b07ddc03caa1ecf53443d15e5e5270e45c5ba31929a730ea622bfb89003d1 8f6b66c8-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=116017 http://acta-arhiv.chem-soc.si/60/60-2-448.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=84159 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
