Influence of the surface nature on the grafted layer at the POE/silica interrace

Written by sctunisie no comments

After the first step of characterization of surface of the silicas chosen as solid supports of the interface of polymer/solid, the 1H NMR technique is used to study behavior of chains. It shows the influence notably of surface nature on the conformation of grafted macromolecules. In fact, in case of precipitation silica, the chains adopt disordered conformations, whereas, in the case of pyrogenic silicas, they form a uniform layer. These behaviors are pointed out by 13C NMR high resolution solid state techniques.
