Abstract:
A protective structure is provided, which includes a porous layer and a surface layer disposed on the porous layer. The porous layer includes a first copolymer, a plurality of pores, and a plurality of first silica particles, wherein the first copolymer is polymerized from a first monomer composition. The first monomer composition includes N,N-dimethylacrylamide and N-vinylpyrrolidone. The surface layer includes a second copolymer, a plurality of fibers, and a plurality of second silica particles, wherein the second copolymer is polymerized from a second monomer composition. The second monomer composition includes N,N-dimethylacrylamide and N-vinylpyrrolidone.
Abstract:
A shear thickening formulation and composite material employing the same are provided. The shear thickening formulation includes inorganic particles and polyethylene glycol. The inorganic particles and the polyethylene glycol have a weight ratio of 3 to 4. The inorganic particles can be silica, aluminum oxide, silicon carbide, nano diamond, or a combination thereof.
Abstract:
A resin composition is provided, which includes a first polymer and a second polymer. The first polymer is formed by a reaction of an epoxy resin modified with a first elastic molecular segment and an epoxy resin curing agent. The second polymer is formed by a polymerization of an acrylate modified with a second elastic molecular segment.
