Abstract: Provided herein is a method for forming a composite. The method can include mixing a plurality of carbon nanotubes (CNTs) and a plurality of magnetic nanoparticles in a non-polar medium. At least some of the plurality of CNTs form entangled CNTs. The method also includes attaching first ones of the plurality of magnetic nanoparticles to exposed surfaces of the entangled CNTs; disentangling the entangled CNTs to form a plurality of dispersed CNTs; and aligning the plurality of dispersed CNTs. The disentangling of the entangled CNTs to form a plurality of dispersed CNTs includes exposing the plurality of magnetic nanoparticles and the plurality of entangled CNTs to electromagnetic energy.

Abstract: Microchannels in hydrogels play an essential role in enabling a smart contact lens. A wearable contact lens is disclosed herein that uses microchannels and connected chambers located in poly-2-hydroxyethyl methacrylate (poly(HEMA)) hydrogel that is used in a commercial contact lens with three-dimensional (3D) printed mold. The corresponding capillary flow behaviors in these microchannels were investigated. Different capillary flow regimes were observed in these microchannels, depending on the hydration level of the hydrogel material. In particular, it was found that a peristaltic pressure could reinstate flow in a dehydrated microchannel, indicating the motion of eye-blinking may help tear flow in a microchannel-containing contact lens. Colorimetric pH and electrochemical Na+ sensing capabilities were demonstrated in these microchannels. Micro-engineered contact lenses formed using poly(HEMA) hydrogel can be used for various biomedical applications such as eye-care and wearable biosensing.

Abstract: The present invention is a composition comprising a) a stable aqueous dispersion of polymer particles functionalized with structural units of a phosphorus acid monomer or a salt thereof and; b) a water-soluble polymer functionalized with structural units of a sulfonic acid monomer or a salt thereof as well as a method comprising mixing the stable aqueous dispersion of the phosphorus acid functionalized polymer particles with the sulfonic acid functionalized polymer, and TiO2. The composition of the present invention is useful as a coatings formulation that provides improved hiding over phosphorus acid functionalized binders that do not include the water-soluble polymer. Alternatively, the same hiding benefit is seen at lower phosphorus acid concentration when the sulfonic acid functionalized polymer is present.
