Crosslinking effect on the deformation and fracture of monodisperse polystyrene-co-divinylbenzene particles
He, Jianying; Zhang, Zhiliang; Kristiansen, Helge; Redford, Keith; Fonnum, Geir; Modahl, Grete (Journal article; Peer reviewed, 2013)This study focuses on the effect of crosslinking density on the mechanical response of polystyrene-co-divinylbenzene (PS-DVB) particles under compression by means of nanoindentation-based flat punch method combined with ... -
Size effect on mechanical properties of micron-sized PS-DVB polymer particles
He, Jianying; Zhang, Zhiliang; Midttun, M; Fonnum, Geir; Modahl, GI; Kristiansen, H; Redford, Keith (Journal article; Peer reviewed, 2008)A nanoindentation based flat punch method has been developed to determine the stress-strain behaviour of single micron-sized Ugelstad polystyrene-co-divinylbenzene (PS-DVB) particles in compression. Five groups of particles ...
