The design of nanocomposite materials is a fast-growing field with many novel and exciting materials such as nanocomposite polymer hydrogels. In particular, the coupling between the chemistry of adsorption and the resulting mechanical properties has been poorly explored. Recently a way has been found to glue together two polymer gels using nanocomposite materials made by polymers and silica nanoparticles (NPs). It is proposed for the first time that spreading a droplet of a silica NP solution on the surface of one gel and then bringing a second gel into contact with it leads to strong adhesion between the two gels.
However, the interaction between the polymer network and the NPs is still not well understood. Modeling the interactions between polymers and silica particles at the quantum level, using density functional theory, will allow us to get insight into the adsorption energy of the polymers on the NPs surface. Moreover, studying this system with coarse-grained molecular dynamics simulations will give us information about the organization of the polymer chains around the silica NPs.
