Abstract:
The evaluating mechanical performance of Π-conjugated Polymer films has important significance for application in the micro electronic devices. In this work, authors studied micro mechanical performance of Π-conjugated polymer, poly[2-methoxy-5-(2’-ethyl hexyloxy)-phenylene vinylene] used nanoindentation technique at room temperature and discussed effect of experimental parameter on the effective elastic modulus and hardness of MEH-PPV film. The experimental result indicates the estimating effective elastic modulus and hardness using O & P formula are correlative with load, holding time, and loading rate. Detail analysis in combination with related literature indicated the effective elastic modulus and hardness of MEH-PPV film are approximately 6.79±0.12GP, 0.37±0.16 GP, respectively. Furthermore, increasing the loading rate could decrease the effective elastic modulus and hardness, which was opposite comparing with typical polymer materials (poly (methyl methacrylate) (PMMA) etc ).
