Novel Graphene Nanoplatelet Embedded Pigmentless Emulsions for Low Cost Paintable Capacitive Sensors and Supercapacitors
获奖作品摘要
Recent efforts on capacitive sensors and supercapacitor designs have worked towards developing materials that can be seamlessly integrated into devices with irregular geometries and form factors. Graphene Nanoplatelets (GnPs) show tremendous potential for novel paintable sensors and energy storage devices. Variable grades of GnPs were used to fabricate specialized graphene composite films. GnP-NCG015 (150nm to 10μm in diameter) and GnP-EG016 were embedded into a durable, waterproof, and pigmentless acrylic emulsion via ice bath assisted sonication at varying loadings (10-30%) for varying times (30-120 minutes) to determine the effect of loading and sonication time on the resulting surface resistivity, specific capacitance and morphology. Cyclic Voltammetry and Surface Resistivity tests characterized the linear increase in performance with higher loadings and sonication times. However, sonication times of 90 minutes and higher created band gaps in the GnP structure resulting in lower performance. The film morphology, characterized by SEM, showed continuous, uniform networks of graphene nanoplatelets in the polymer matrix. Composite films were applied on six arbitrary surfaces and tested with an ASTM D3359 adhesion test tape which demonstrated zero flaking on all substrates. The films exhibit extremely high durability with surface conductivity retention of 95-99.1% when creased or bent. The results of this novel materials research created multi-property graphene nanoplatelet embedded mediums enabling large interactive surfaces and energy storage devices, on any surface or geometry, via a novel paintable architecture costing less than $1 per square foot.

学科简介：材料科学 Materials Science
The study of the integration of various materials forms in systems, devices, and components that rely on their unique and specific properties. It involves their synthesis and processing in the form of nanoparticles, nanofibers, and nanolayered structures, to coatings and laminates, to bulk monolithic, single-/poly-crystalline, glassy, soft/hard solid, composite, and cellular structures. It also involves measurements of various properties and characterization of the structure across length scales, in addition to multi-scale modeling and computations for process-structure and structure-property correlations.
Subcategories:
Biomaterials (BIM): Studies involving any matter, surface, or construct that interacts with biological systems. Such materials are often used and/or adapted for a medical application, and thus comprise whole or part of a living structure or biomedical device which performs, augments, or replaces a natural function.
Ceramic and Glasses (CER): Studies involving materials composed of ceramic and glass – often defined as all solid materials except metals and their alloys that are made by the high-temperature processing of inorganic raw materials.
Composite Materials (CMP): Studies that integrate multiple materials such as ceramics, fiber, metals or polymers to create a superior and unique material.
Computation and Theory (COM): Studies that develop and apply theoretical methods and/or use computer modeling to design new materials, predict material behavior under differing environmental conditions, understand energy transfer, etc.
Electronic, Optical and Magnetic Materials (ELE): The study and development of materials used to form highly complex systems, such as integrated electronic circuits, optoelectronic devices, and magnetic and optical mass storage media. The various materials, with precisely controlled properties, perform numerous functions, including the acquisition, processing, transmission, storage, and display of information.
Nanomaterials (NAN): The study and development of nanoscale materials; materials with structural features (particle size or grain size, for example) of at least one dimension in the range 1-100 nm.
Polymers (POL): The study and development of polymers; materials that have a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins.
Other (OTH): Studies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.
