The Wetting Behavior of Polymer Droplets: Effects of Droplet Size and Chain Length
Monte
Carlo computer simulations were utilized to probe the behavior
of homopolymer droplets adsorbed at solid surfaces as a function of
the number of chains making up the droplets and varying droplet sizes.
The wetting behavior is quantified via the ratio of the perpendicular
to the parallel component of the effective radii of gyration of the
droplets and is analyzed further in terms of the adsorption behavior
of the polymer chains and the monomers that constitute the droplets.
This analysis is complemented by an account of the shape of the droplets
in terms of the principal moments of the radius of gyration tensor.
Single-chain droplets are found to lie flatter and wet the substrate
more than chemically identical multichain droplets, which attain a
more globular shape and wet the substrate less. The simulation findings
are in good agreement with atomic force microscopy experiments. The
present investigation illustrates a marked dependence of wetting and
adsorption on certain structural arrangements and proposes this dependence
as a technique through which polymer wetting may be tuned
