Polymer Translocation through Nanometer Pores

Maria-Alexandra Paun

In this paper the loaded polymer transport and its escape via a nanometer size aperture, virtually by nanomembrane, the polymer being moved by an exterior electrostatic field, has been studied. Assuming a linear dependency of the friction coefficient on th ...

Mechanical Activation of Chemical Bonds at Polymer Interfaces

Julian Nicolas Bleich

Polymer brushes are a specific class of polymer thin films in which each chain is tethered to the underlying substrate via one chain end. In sufficiently densely grafted assemblies, the individual polymer chains are forced into an extended chain conformati ...

Viscoelastic behavior of suspensions of reduced graphene oxide nanoparticles in epoxy

László Forró, Yves Leterrier, Arnaud Magrez, Maryam Majidian

The viscoelastic behavior of dilute suspensions of reduced graphene oxide (RGO) nanoparticles in a liquid SU8 epoxy dissolved in gamma butyrolactone was investigated at RGO concentrations in the range from 0.16 to 1.07 vol. %. Our results revealed that the ...
