  • Patent number: 10982165
    Abstract: Disclosed are materials that possess both low adhesion and the ability to absorb water. The material passively absorbs water from the atmosphere and then expels this water upon impact with debris, to create a self-cleaning layer. The lubrication reduces friction and surface adhesion of the debris (such as an insect), which may then slide off the surface. The invention provides a material comprising a continuous matrix including a polymer having a low surface energy (less than 50 mJ/m2) and a plurality of inclusions, dispersed within the matrix, each comprising a hygroscopic material. The continuous matrix and the inclusions form a lubricating surface layer in the presence of humidity. The material optionally contains porous nanostructures that inject water back onto the surface after an impact, absorbing water under pressure and then releasing water when the pressure is removed. The material may be a coating or a surface, for example.

  • Patent number: 10975266
    Abstract: In some variations, the invention provides a curable adhesive formulation comprising a curable liquid precursor capable of frontal polymerization, wherein the liquid precursor comprises a monomer and a polymerization catalyst, and frontal-polymerization-triggering susceptors in contact with, or contained within, the liquid precursor. The susceptors may include conducting and/or magnetic solid particles capable of induction heating in the presence of a remotely applied electromagnetic field. Other variations provide a polymer-curing system comprising a curable liquid precursor, frontal-polymerization-triggering susceptors, and an apparatus configured to remotely produce an alternating electromagnetic field in line-of-sight with the susceptors (but not necessarily in line-of-sight with the liquid precursor), thereby generating induction heating to initiate the frontal polymerization. The susceptors may be about 0.1 wt % to about 50 wt % of the curable formulation.

  • Patent number: 10968355
    Abstract: We have demonstrated reversibly reducing metal-ion crosslinkages in polymer systems, by harnessing light, creating a dynamic and reversible bond. The reduction induces chemical and physical changes in the polymer materials. Some variations provide a polymer composition comprising: a polymer matrix containing one or more ionic species; one or more photosensitizers; and one or more metal ions capable of reversibly changing from a first oxidation state to a second oxidation state when in the presence of the photosensitizers and light. Some embodiments employ urethane-based ionomers capable of changing their crosslinked state under the influence of a change in counterion valance, using light or chemical reducing agents. This invention provides films, coatings, or objects that are reversible, re-mendable, self-healing, mechanically adjustable, and/or thermoplastic/thermoset-switchable.

  • Patent number: 10932399
    Abstract: Examples include a method of forming an electromagnetic shielding material, the method including: applying a magnetic field to a precursor material that includes first ferromagnetic particles embedded within a first portion of a matrix material and second ferromagnetic particles embedded within a second portion of the matrix material, thereby causing the first ferromagnetic particles and the second ferromagnetic particles to move such that longitudinal axes of the first ferromagnetic particles and the second ferromagnetic particles become more aligned with the magnetic field; thereafter forcing the first portion of the matrix material through a filter, thereby moving the first ferromagnetic particles from the first portion of the matrix material into the second portion of the matrix material; and curing the second portion of the matrix material to form the electromagnetic shielding material.

  • Patent number: 10865267
    Abstract: This invention provides durable, low-ice-adhesion coatings with excellent ice-adhesion reduction. Some variations provide a low-ice-adhesion composition comprising a composite material containing at least a first-material phase and a second-material phase that are nanophase-separated on a length scale from 10 nanometers to less than 100 nanometers, wherein the first-material phase and the second-material phase further are microphase-separated on a length scale from 0.1 microns to 100 microns. The larger length scale of separation is driven by an emulsion process, which provides microphase separation that is in addition to classic molecular-level phase separation. The composite material has a glass-transition temperature above ?80° C. The coatings may be characterized by an AMIL Centrifuge Ice Adhesion Reduction Factor up to 100 or more. These coatings are useful for aerospace surfaces and many other applications.
