Query: Neutral-cluster implantation in polymers by computer experiments   In this work we perform atomistic model potential molecular dynamics
simulations by means of state-of-the art force-fields to study the implantation
of a single Au nanocluster on a Polydimethylsiloxane substrate. All the
simulations have ben performed on realistic substrate models containing up to
4.6 millions of atoms having depths up to 90 nm and lateral dimensions up to 25
nm. We consider both entangled-melt and cross-linked Polydimethylsiloxane
amorphous structures. We show that even a single cluster impact on the
Polydimethylsiloxane substrate remarkably changes the polymer local temperature
and pressure. Moreover we observe the presence of craters created on the
polymer surface having lateral dimensions comparable to the cluster radius and
depths strongly dependent on the implantation energy. Present simulations
suggest that the substrate morphology is largely affected by the cluster impact
and that most-likely such modifications favor the the penetration of the next
impinging clusters.
