Solid surface polymer melts molecular models

Such behavior has been interpreted in terms of a molecular model proposed by Brochard-Wyart and de Gennes [143] and further refined [145,146]. The first version of these models considers a solid surface bearing a few end grafted polymer chains, with a surface density, G, below the onset of the mushroom regime gAT<1, with N the polymerization index of the anchored chains). The melt chains have a polymerization index P. Both N and P are assumed to be much larger than Ne, the average number of monomers needed to form an entanglement. Thus the... 

The model adopted, hairy clay platelets (HCPs), was formulated considering the reduction of molecular mobility near the clay platelet crystalline surface [Utracki and Lyngaae-Jprgensen, 2002]. The data show that polymer adsorbed from solution or melt on a crystalline solid forms a layer whose thickness is comparable to the radius of gyration, the macromolecules adsorb physically on a solid surface,...
