  • Patent number: 10867719
    Abstract: Disclosed are compositions of electroactive polymers (EAPs) having improved performance stability. In the EAP compositions, a cross-linked polymer is deposited onto the surface of the EAP by vapor-deposition methods. Upon contact with an aqueous solution (e.g., an aqueous electrolyte solution), the vapor-deposited polymeric network becomes a hydrogel that encapsulates the EAPs. By modulating precursors and vapor deposition conditions, the mesh size of the resultant hydrogel coatings can be controlled to accommodate the key species that interact with the EAPs.

  • Patent number: 10755942
    Abstract: Disclosed is a method for the fabrication of polymeric topcoat via initiated chemical vapor deposition (iCVD) or photoinitiated chemical vapor deposition (piCVD) in conjunction with directed self-assembly (DSA) of block copolymers to generate high resolution patterns. A topcoat deposited by iCVD or piCVD allows for conformal, ultra-thin, uniform, pinhole-free coatings. iCVD or piCVD topcoat enables the use of a diversity of block copolymer (BCP) materials for DSA and facilitates the direct and seamless integration of the topcoats for a pattern transfer process.

  • Patent number: 10583677
    Abstract: Methods of printing nanoparticulate ink using nanoporous print stamps are disclosed. A nanoporous print stamp can include a substrate, a patterned arrangement of carbon nanotubes disposed on the substrate, and a secondary material disposed on the carbon nanotubes to reduce capillary-induced deformation of the patterned arrangement of carbon nanotubes when printing nanoparticulate ink. Some methods include loading a nanoporous print stamp with nanoparticulate colloidal ink such that the nanoparticulate colloidal ink is drawn into microstructures of the patterned arrangement of carbon nanotubes via capillary wicking. Nanoparticulate colloidal ink can include nanoparticles dispersed in a solution.

  • Patent number: 10543516
    Abstract: Liquid-impregnated textured coatings containing one or more materials on a variety of surfaces are described herein. The coatings can be prepared by chemical vapor deposition techniques or other techniques known in the art. The texture can be random, fractal, or patterned. The texture can be pores, cavities, and/or micro- and/or nanoscale features/structures. The capillary forces arising from the nano- or microscopic texture of the coating stabilizes the liquid within the textured features and at the surface of the coating resulting in non-wetting properties for a variety of surfaces. They coatings may be formed in a single layer or as multiple layers. In order to maximize ease of deposition and processing, the coating may be formed of graded composition to optimize both bulk and surface properties without the need for multiple coatings.

  • Patent number: 10510971
    Abstract: Described are materials and methods for fabricating low-voltage MHz ion-gel-gated thin film transistor devices using patternable defect-free ionic liquid gels. Ionic liquid gels made by the initiated chemical vapor deposition methods described herein exhibit a capacitance of about 1 ?F cm?2 at about 1 MHz, and can be as thin as about 20 nm to about 400 nm.

  • Publication number: 20190241785
    Abstract: Disclosed are thermally conductive quinoid-type conjugated polymer thin films. One such film comprises conjugated poly(3-hexylthiophene) (P3HT). The thin films can be fabricated using oxidative chemical vapor deposition (oCVD), which offers unique advantages for integrating polymer films into various devices. By avoiding the use of solvents in the deposition of monomers and oxidants and undesirable solvent-derived surface-tension driven effects, such as dewetting, the oCVD coatings can conformally coat complex geometries, can be scaled to large areas, and can be fabricated at relatively low substrate temperatures on electrically insulating substrates. Disclosed is the formation of ordered polymer structures with rigid backbones achieved by oCVD with stacking in the transverse direction via ?-? interactions. P3HT films with record-high thermal conductivity of 2.2 W/m-K near room temperature have been prepared.

  • Patent number: 10155843
    Abstract: Described herein are facile, one-step initiated plasma enhanced chemical vapor deposition (iPECVD) methods of synthesizing hyper-thin (e.g., sub-100 nm) and flexible metal organic covalent network (MOCN) layers. As an example, the MOCN may be made from zinc tetraphenylporphyrin (ZnTPP) building units. When deposited on a membrane support, the MOCN layers demonstrate gas separation exceeding the upper bounds for multiple gas pairs while reducing the flux as compared to the support alone.

  • Patent number: 9957618
    Abstract: Described herein are reactors capable of sequentially or simultaneously depositing thin-film polymers onto a substrate by oxidative chemical vapor deposition (oCVD), initiated chemical vapor deposition (iCVD), and plasma-enhanced chemical vapor deposition (PECVD). The single-unit CVD reactors allow for the use of more than one CVD process on the same substrate without the risk of inadvertently exposing the substrate to ambient conditions when switching processes. Furthermore, the ability to deposit simultaneously polymers made by two different CVD processes allows for the exploration of new materials. In addition to assisting in the deposition of polymer films, plasma processes may be used to pretreat substrate surfaces before polymer deposition, or to clean the internal surfaces of the reactor between experiments.
