Abstract: The present invention generally relates to colloidal systems, which may include colloidal particles and/or other types of particles. One aspect of the invention is generally directed to a system comprising fluidic droplets that can be at least partially solidified, e.g., to form colloidal particles. In some embodiments, particles comprising an at least partially solid outer phase encapsulating an inner phase are formed. The inner phase may be any phase, e.g., a solid, a liquid, or a gas. In some cases, solidifying at least a portion of the outer phase of the droplets to form particles may increase the stability of the particles and/or the colloidal system containing the particles. In one set of embodiments, melting or liquefying the outer phase of the particles (for example, by heating the particle to a temperature above a threshold temperature) can allow release of an agent contained within the inner phase, and/or allow the inner phase to coalesce with a phase external to the particles.

Abstract: A transparent, semi-interpenetrating network comprises a first phase of a linear noncrosslinked isobutene polymer and a second phase of a crosslinked polymer. The crosslinked polymer is obtained through copolymerization of a first ethylenically unsaturated monomer and of a second ethylenically unsaturated monomer, wherein the first ethylenically unsaturated monomer is a cycloalkyl(meth)acrylate and the second ethylenically unsaturated monomer is selected from linear and branched C1-C20 alkyl(meth)acrylates. By varying the ratio of the first ethylenically unsaturated monomer relative to the second ethylenically unsaturated monomer, the properties, such as vibration damping properties, of the semi-interpenetrating network can be controlled.
