Viscosity Changes

We demonstrate a new method to study the viscosity of PNC thin films, consisting of polymer grafted nanoparticles (PGNPs) embedded in un-entangled homopolymer melt films, using atomic force microscopy based force–distance spectroscopy.

In this paper, we report atomic force microscopy (AFM) images of a tubular polymer and its supermolecular polymer thin films, operated in contact mode at room temperature in air. The configuration models are also calculated using molecular dynamics. The diameter of the polymer nanotube is about 0.7 nm, the smallest size a tube can have. The results of calculation agree with the experimental results.
