The present invention relates to a thermoplastic composite article and a manufacturing method thereof. The thermoplastic composite article provided by the present invention comprises a matrix zone and a functional zone. The matrix zone comprises a composite substrate and a coating, the coating covers a surface of the composite substrate, and the coating and the functional zone are obtained by a reaction of a coating composition comprising the following components: one or more polyisocyanates, and one or more H-active polyfunctional compounds, wherein the H-active polyfunctional compounds are preferably one or more polyols. The functional zone comprises a region of the coating which extends into the cut-out section of the substrate. The method for manufacturing the thermoplastic composite article provided according to the present invention is characterized by a simple process, high efficiency, a high yield and environmental friendliness; and the obtained thermoplastic composite article, especially an electronic product housing, can have good electrical signal transmission performance or structural components.

The invention relates to a vehicle utilizing a LiDAR sensor system for driver assistance systems. A composition consisting of a thermoplastic material based on polycarbonate is used here for forming the substrate layer of a cover for the sensor with respect to the surroundings. The cover has a specific topcoat layer in order to achieve high abrasion resistance and weathering stability.

Fire protective compositions include colloidal silica solids, clay, a low biopersistence fiber or refractory ceramic fiber, water, and optionally a chelating agent. Methods of using the fire protective compositions include providing a polymeric foam substrate, applying the fire protective composition on the polymeric foam substrate, and allowing the fire protective composition to dry.

A production method for a polyimide with a black resin cured film includes a process of obtaining the black resin cured film by curing a black resin composition on the polyimide. The process of obtaining the black resin cured film includes a process of processing the black resin composition with a predetermined spray impact. A distance from a point where a line that is perpendicular to a surface of the polyimide and that passes through a substrate-adhered edge between the black resin cured film and the polyimide intersects a top portion of the black resin cured film to an edge of the top portion is 25 m or less.

Fire protective compositions include colloidal silica solids, clay, a low biopersistence fiber or refractory ceramic fiber, water, and optionally a chelating agent. Methods of using the fire protective compositions include providing a polymeric foam substrate, applying the fire protective composition on the polymeric foam substrate, and allowing the fire protective composition to dry.

A lithium ion battery including a core-shell structured fire extinguishing particle is disclosed. When the battery is overheated to a predetermined temperature, a shell of the fire extinguishing particle coated on one surface or both surfaces of a porous separator is melted, a fire extinguishing material disposed in an inner space of the shell is released into an electrolytic solution of the battery, and as a result, it is possible to prevent the battery from being ignited or exploded even though the battery is overheated. Further, the melted shell clogs pores of the porous separator to block lithium ions from moving, such that the battery is blocked from being driven, thereby preventing the battery from being overheated any more.

A single-layer or multi-layer, biaxially oriented polyester film is provided bearing on at least one film surface a coating for transparency increase. The film has a particle fraction of not more than 0.5% and the coating is a dried water-based or solvent-based solution and/or dispersion having a dry coat thickness of 60-130 nm. The coating includes at least one acrylic acid-based and/or methacrylic acid-based polymer and at least one alkylphosphonate and/or oligo-alkylphosphonate. The coating has a refractive index n<1.64 and a phosphorus fraction of between 2 and 18%. The inventive film is suitable for producing greenhouse energy-saving sheets, particularly for the growing of plants with exacting light demands such as tomatoes. The film has specific transparency properties, high UV stability and good fire properties. The invention further relates to methods for polyester film production and also to the use thereof in greenhouses.
