AFM image of the week

20160531-PBF-CHCl3_HexaF_90-10pcvol-40mgmL-filtered-baked-100C72-from180C_1_001.jpg

This I present you an AFM topography image of a furan-based polymer thin film. The film was prepared by spin coating onto SiOx wafers and after preparation it was subjected to thermal annealing to promote crystallization. The AFM shows the development of needle-like crystals on the thin film surface. The features have lengths between 100 – 600 nm and widths (needle diameter) of about 60 nm. This work is part of our collaboration with Dr. Michelina Soccio at the Università di Bologna.

Fête de l’Iris 2016

The artwork by Jean Spièce, Simone Napolitano and myself was selected for the Expo of the ULB Faculty of Science, and exposed at the ULB center at the Fête de l’Iris 2016.  The poster, entitled “Let’s go curvy”, shows an AFM topography image of curvilinear PLLA nanocrystals. More info on this project can be found here.

The image of the week

I’m starting this week with a SEM image of poly(methyl metacrylate) microspheres.

Starting from the commercial polymer, nanopsheres were prepared following the “Dialysis nanoprecipiation protocol”, where, using a dialysis membrane, a polymer solution goes through a careful precipitation process.

More on this technique can be found here and here.

Have the best possible week!!
