  • Patent number: 11371961
    Abstract: A sensor is achieved by applying a layer of a mixture that contains polymer and conductive particles over a substrate or first surface, when the mixture has a first viscosity that allows the conductive particles to rearrange within the material. An electric field is applied over the layer, so that a number of the conductive particles are assembled into one or more chain-like conductive pathways with the field and thereafter the viscosity of the layer is changed to a second, higher viscosity, in order to mechanically stabilise the material. The conductivity of the pathway is highly sensitive to the deformations and it can therefore act as deformation sensor. The pathways can be transparent and is thus suited for conductive and resistive touch screens. Other sensors such as strain gauge and vapour sensor can also be achieved.

  • Patent number: 11359116
    Abstract: Conventionally, there was a need to add a large amount of electroconductive particles for improving conductivity, but when the electroconductive particles were added too much, initial viscosity was increased, and at the same time, it was difficult to stabilize preservation stability. However, conductivity can be improved without adding a large amount of the electroconductive particles by selecting a monomer, and at the same time, preservation stability can be stabilized by using certain electroconductive particles. A thermocurable electroconductive adhesive including components (A) to (D): component (A): an oligomer having a (meth)acryl group; component (B): a monomer having one methacryl group in a molecule; component (C): an organic peroxide having a specific structure; and component (D): electroconductive particles which are surface-treated with a stearic acid.

    Abstract: Methods include producing tunable carbon structures and combining carbon structures with a polymer to form a composite material. Carbon structures include crinkled graphene. Methods also include functionalizing the carbon structures, either in-situ, within the plasma reactor, or in a liquid collection facility. The plasma reactor has a first control for tuning the specific surface area (SSA) of the resulting tuned carbon structures as well as a second, independent control for tuning the SSA of the tuned carbon structures. The composite materials that result from mixing the tuned carbon structures with a polymer results in composite materials that exhibit exceptional favorable mechanical and/or other properties. Mechanisms that operate between the carbon structures and the polymer yield composite materials that exhibit these exceptional mechanical properties are also examined.

  • Patent number: 11270872
    Abstract: Cathode structures are disclosed for use with pulsed cathodic arc deposition systems for forming diamond-like carbon (DLC) films on devices, such as on the sliders of hard disk drives. In illustrative examples, a base layer composed of an electrically- and thermally-conducting material is provided between the ceramic substrate of the cathode and a graphitic paint outer coating, where the base layer is a silver-filled coating that adheres to the ceramic rod and the graphitic paint. The base layer is provided, in some examples, to achieve and maintain a relatively low resistance (and hence a relatively high conductivity) within the cathode structure during pulsed arc deposition to avoid issues that can result from a loss of conductivity within the graphitic paint over time as deposition proceeds. Examples of suitable base material compounds are described herein where, e.g., the base layer can withstand temperatures of 1700° F. (927° C.).
