(1) A maximum peak height roughness (SRp) is 1.2 μm to 1.6 μm. (2) An arithmetic average roughness (SRa) is 0.024 μm to 0.045 μm. (3) A tensile strength in a longitudinal direction and a width direction is 180 MPa to 300 MPa. (4) A haze is 7% or less.

A polymer composite formed from an epoxy based polymer and an amino-graphene. The epoxy based polymer forms a polymer matrix and the amino graphene is dispersed throughout the polymer matrix. Further, a graphene is functionalized with 3,5-dinitrophenyl groups to form functionalized graphene and one or more amine functional groups form Meisenheimer complexes with the functionalized graphene to form the amino-graphene. An associated method of making the polymer composite is also provided.

A resin-reinforcing filler of the present invention includes: plate-like, spherical, or fibrous filler substrates; and a coating covering at least a portion of a surface of each of the substrates. The coating contains nanofibers having an average fiber width of 1 nm to 900 nm.

Embossing resins, methods of manufacturing such resins, and electrokinetic display system, which includes display cells containing such resins. The resins include a fluoropolymer in weight percentage 5%-60%, a difunctional diluent in weight percentage 0-30%, a monofunctional diluent in weight percentage 0-40%, a urethane diacrylate or functionalized nanoscale material, e.g., a functionalized urethane material, in weight percentage 5-50%, a photoinitiator in weight percentage 0.5-5%, and a surfactant in weight percentage less than 0.5%. The difunctional diluent may be Hexanediol Diacrylate, and the monofunctional diluent may be a monofunctional hydrocarbon. The resins are made by identifying a target index of refraction for a cured state thereof, and combining together, by weight percentage, the constituent components to produce the liquid state version of the embossing resin having a desired composite index of refraction.
