Poster summary

Nanoparticles with grafted polymer chains have been a popular object of study for some time, but only recently the research focus has shifted from the particles with fixed binding sites towards the ones with mobile anchors. When two such particles approach each other, the grafted chains can migrate from the near-contact area, redistributing non-uniformly on the particles’ surfaces. Here, we quantitatively explore how the interactions between spherical colloid particles are modified in the presence of mobile surfactants via Monte Carlo simulations. We study how the forces between the core particles depend on the anchor site distribution and chain length and compare our results to the system with fixed anchors. The research would be useful in predicting the colloid/polymer mixture behaviour (e.g. self-assembly of patchy particles) and designing coatings, rubber and ceramic materials.
