Study of the aggregation behavior of Janus particles by coupling experiments and Brownian dynamics simulations.

摘要: Abstract Hypothesis New colloids such as inverse patchy particles or Janus are considered smart building blocks in the development of innovative and performant materials. For example, control self-assembly oxide-based charged is interesting for ceramic shaping. Thus, synthesis silica based well a detailed study their behavior suspension presented this paper. Experiments Fluorescent partially modified surface by grafting amine groups using Pickering emulsion route. Zeta potential measurements, sedimentation tests confocal microscopy observations carried out to analyze aggregation obtained aqueous function patch size pH. Brownian dynamics simulations also performed better understand aggregate structures. Findings The synthesized silica-based can be tuned modifying experimental parameters, elongated on contrary more compact structures could observed. This makes promising build new
