  • Patent number: 11247230
    Abstract: An object has a durable superhydrophic, self-cleaning, and icephobic coating includes a substrate and a layer disposed on the substrate, the layer resulting from coating with a formulation having an effective amount of hierarchical structuring micro/nanoparticles, liquid silane having one or more groups configured to graft to a hierarchical structuring micro/nanoparticle and at least another group that results in hydrophobicity. The hierarchical structuring micro/nanoparticles are dispersed in the liquid silane. Another effective amount of synthetic adhesive, selected from thermosetting binders, moisture curing adhesives or polymers that form a strong interaction with a surface, is in solution with a solvent. Upon curing, the layer has a contact angle greater than 90° and a sliding angle of less than 10° and, less than 5% of an area of the layer is removed in a Tape test.

  • Patent number: 8841239
    Abstract: Nanoscale patterns prepared by lithography are used to direct the self-assembly of amphiphilic molecules to form patterned nanosubstrates having a desired distribution of chemical functional moieties. These patterns can be fabricated over a large area and require no special limitations on the chemistry the assembled amphiphiles. Hydrophilic/hydrophobic patterns can be created and used to direct the deposition of a single functional component to specific regions of the surface or to selectively assemble polymer blends to desired sites in a one step fashion with high specificity and selectivity. The selective deposition of functional moieties on a patterned surface can be based on electrostatic forces, hydrogen bonding, or hydrophobic interactions.

  • Patent number: 6573303
    Abstract: Materials ranging from impact-modified thermoplastics to thermoplastic elastomers (TPE) can be obtained from blends of phase compatibility-treated recycled thermoset rubber with thermoplastic polymers by varying the ratio of components in the blend, or by changing the components themselves. The rubber component may include carbon black, or other fillers and additives, and it may be selected from among a variety of thermoset rubbers, both natural and synthetic. The thermoset rubber component can be obtained from a rubber material recycled according to a variety of known techniques. The thermoplastic component can be virtually any suitable polymer, the properties of which can be advantageously modified by combination with a rubber. Polyolefins are among the more preferred thermoplastic components.
