Theoretical analyzing of monomers adsorbing in nano-slits

A revised model based on Lattice-Density-Function Theory (LDFT) was built in this paper and was used to indicate the adsorbing behaviors of monomers in nano slits. This work tried to establish a theoretical model and get the fundamental mechanisms of the in situ-monomer-intercalation process which is the most common production method of polymer-layer silicate intercalated nanocomposite (PLSN). According to the results, the multilevel adsorption and 3D phase transition phenomenon in nano slits predicted by original LDFT do not exit in reality. They are probably aroused by system errors caused by simple mean field approximation treatments. The nano slits have obvious boundary effects on density profile distribution of monomers.
