  • Patent number: 10428193
    Abstract: The invention relates to a process for producing a prepreg based on polyurethane, which is notable for high storage stability at room temperature, a two-stage reaction mechanism, and adjustable adhesion on metal surfaces. It is based on the problem of making the surface tack of the prepregs controllable during processing. The solution is to assemble the PU mixture from which the matrix originates at a later stage such that the glass transition temperature of the thermoplastic polymer is above 30° C. For this purpose, the invention proposes two basically independent but certainly synergistic measures, namely: i) use of a polyol compound or a mixture of a number of polyol compounds as binder, the OH number or mean OH number of which is above 300 mg KOH/g, ii) choice of the proportion of hardener corresponding to the co-binder in the reactive composition at greater than 2% by weight, based on the total solids content of the reactive composition.

  • Patent number: 10305121
    Abstract: There is provided a frame body used for a cell of a redox flow battery, that can improve heat dissipation of an electrolyte in a slit and can suppress rise of the temperature of the electrolyte. It is a frame body used for a cell of a redox flow battery, comprising: an opening formed inside the frame body; a manifold allowing an electrolyte to pass therethrough; and a slit which connects the manifold and the opening and forms a channel of the electrolyte between the manifold and the opening, the slit having a pair of sidewalls facing each other in a cross section orthogonal to a direction in which the electrolyte flows, the slit having, at at least a portion thereof in the slit's depthwise direction, a width narrowing portion allowing the sidewalls to have a spacing narrowed in the depthwise direction.

  • Patent number: 10297392
    Abstract: A capacitor whose electrical properties can be stable under a variety of different conditions is provided. The solid electrolyte of the capacitor is formed from a combination of an in situ polymerized conductive polymer and a hydroxy-functional nonionic polymer. One benefit of such an in situ polymerized conductive polymer is that it does not require the use of polymeric counterions (e.g., polystyrenesulfonic anion) to compensate for charge, as with conventional particle dispersions, which tend to result in ionic polarization and instable electrical properties, particularly at the low temperatures noted above. Further, it is believed that hydroxy-functional nonionic polymers can improve the degree of contact between the polymer and the surface of the internal dielectric, which unexpectedly increases the capacitance performance and reduces ESR.

  • Patent number: 10287167
    Abstract: Existing methods of producing high quality graphene/graphite oxides are generally accomplished by exfoliating graphite into flakes and oxidizing the graphite flakes with strong oxidizers under extreme conditions and require careful purification. The oxidizers are typically strong acids used in high concentrations at elevated temperatures requiring complicated purification processes to yield oxidized graphene/sheets. The existing processes can cost up to $12,000/gram. This invention uses a mild oxidant combined with mechanical processing where the sole products are oxidized graphite/graphene and water without the need for further purification.

  • Patent number: 10288208
    Abstract: A corrosion protected metal pipe for installation in an offshore structure or for producing a pipeline laid in water is provided. The metal pipe has an at least two-layer covering on the pipe with a lower layer facing the pipe and an upper layer on a side of the lower layer not facing the pipe is provided. The layers are formed such that the lower layer is electrically conductive and the upper layer is electrically insulating, the lower layer is optically contrasting to the upper layer, or the lower layer is electrically conducting and optically contrasting to the upper layer and the upper layer is electrically insulating. Thus, in the event of damage to the layer or layers lying above, a visual or electrical signal can be detected. Damage to the corrosion protection covering can therefore be detected easily and, if appropriate, reported by remote monitoring.

  • Patent number: 10269467
    Abstract: An anisotropic conductive film is thermo-polymerizable and includes an electrically insulating base layer, an adhesive layer, an intermediate layer sandwiched therebetween, and electrically conductive particles retained by any of the layers. The intermediate layer and the adhesive layer each have a melt viscosity higher than the melt viscosity of the electrically insulating base layer. The electrically conductive particles are independent of one another when the anisotropic conductive film is viewed in plan. The modulus of elasticity of the anisotropic conductive film as a whole, at 100° C., after thermal polymerization, is higher than 1800 MPa.
