intermolecular force

[‚in·tər·mə′lek·yə·lər ′fōrs]
(physical chemistry)
The force between two molecules; it is that negative gradient of the potential energy between the interacting molecules, if energy is a function of the distance between the centers of the molecules.

In particular, the interplay between the material properties of the liquid (density, viscosity and surface tension) with slip length and (stabilizing) intermolecular forces will be considered.
This is due to the fact that in condensed blends, the intermolecular force among polymers is stronger thus the intrinsic characteristic length exceeds the attraction force from the substrate surface.

After the reaction, there still exists polar -NH- group, which can form hydrogen bonds among the adjacent molecular chains and enhance the intermolecular force to a certain extent.
However, depending on intramolecular and intermolecular forces acting between two soft segment chains, it could be somewhat different between these two cases.
Based on this, we then mechanically characterize the principal values of the stress tensor: They represent averages of the pressures created by the distributions of intermolecular forces inside material.
A detailed description of the hydrogenbonding patterns in a given system must be derived from analysis of specific experimental data, and as such, a sound knowledge and understanding of the role that intermolecular forces play in supramolecular assembly is generally obtained from systematic crystallographic studies.
Intermolecular forces also influence these properties.
Nonreactive silicones are based on polydimethylsiloxanes (PDMS), which impart desirable properties as a result of their flexible polymer backbone, stable bonds and low intermolecular forces.
