Stimulus-Responsive Liquid Marbles

摘要

Over the past decade or so there has been increasing interest in the adsorption of colloidal particles at the air/water, oil/water and solid/water interfaces. This emerging field has led to new concepts and materials such as "colloidosomes", "armored bubbles", "dry water", and "liquid marbles", with potential applications being suggested in microencapsulation and biotechnology. In particular, "liquid marbles" can be prepared by using highly hydrophobic particles based on either fluorinated lycopodium powder or partially alkylated silica. In principle, polymer latexes should be particularly attractive for preparing "liquid marbles", since they can be readily designed with specific surface chemistries.
