A polyurethane composition raw material liquid agent comprises a polyol or an isocyanate, and a filler. The polyurethane composition raw material liquid agent has a viscosity at 25° C. and a rotation speed of 60 rpm of 950 mPa.Math.s or less, and is filled in at least one cartridge-like container of a caulking gun that includes two cartridge-like containers and is capable of mixing two components.

The present invention relates to a method for preparing a benzoxazine-containing resin composition and a prepreg and a laminate made therefrom. The method for preparing a benzoxazine-containing resin composition is adding an acidic filler to a benzoxazine-containing resin composition. By adding an acidic filler to the benzoxazine-containing resin composition, the present invention promotes greatly the polymerization reaction of benzoxazine and epoxy resin, reduces the curing temperature required for polymerization of benzoxazine and epoxy resin. The laminate prepared from the benzoxazine-containing resin composition, to which an acidic filler is added, has high anti-stripping stability, high glass transition temperature, low water absorption, high heat resistance, high bending strength and good processability, and can achieve low coefficient of thermal expansion.

Thermally-conductive gap fillers are described. The gap fillers comprise an aziridino-functional polyether polymer and thermally conductive particles. Initiators suitable for such systems ae also described. Such gap fillers may be used in various applications including the manufacture of battery modules and subunits.

A sandwich-type graphene composite structure formed of carbon-coated silicon nanoparticles and graphene, and a method for manufacturing the same are provided. The sandwich-type graphene composite structure is formed of a carbon-coated silicon graphene through an environmentally friendly filtration process. The formed sandwich-type graphene composite structure relieves the volume expansion of the silicon. In addition, the carbon coated on the silicon surface improves electrical conductivity and may be used as a high-capacity anode material.
