  • Patent number: 11459470
    Abstract: Described is a curable composition that includes a salt comprising an alkali cation or rare earth metal ion and a counter ion which is the conjugate base of a superacid, a silicon containing binder, and an additive having a formula R1-O—[(CH2—CHR3)-O]n—R2, in which R1 and R2 represent H or an alkyl group, R3 is H or methyl, and n is an integer ranging from 2 to 200. Said composition is typically provided as a coating or hard coating. When cured, the composition provides good antistatic performance on its surface or to a surface on which it is applied. The composition when formed may also provide high optical transparency. The composition when formed exhibits low haze and good mechanical properties, such as good abrasion resistance, or good scratch resistance, or good mar resistance to its surface or to the surface on which it is applied.

  • Patent number: 11446885
    Abstract: Disclosed is a friction-reducing and anti-wear composite material for a wading kinematic pair and a method of preparing the same. The friction-reducing and anti-wear composite material is prepared from carbon fiber (CF) among inorganic fillers, polyimide (PI) and polyether ether ketone (PEEK). These three materials are wet-mixed, dried and placed in a mold followed by curing by a heat press. The cured product is cooled and demolded to obtain the CF/PI/PEEK friction-reducing and anti-wear composite material for a wading kinematic pair. Tribological properties of the PEEK material are enhanced due to synergistic effect arising from hybrid organic-inorganic filling. The friction-reducing and anti-wear composite material provided in the invention has significantly reduced friction coefficient and wear volume loss under the seawater environment.

  • Patent number: 11389757
    Abstract: A composite absorbent filter media having adsorption and/or absorption properties for the filtration of ester oils from a liquid includes a graphene and/or graphite composite mixed into a final emulsion, which is subsequently heat treated or cured, cooled, compressed, and dried. The resultant adsorption/absorption media is then disposed within a plug structure having an ingress and egress for liquids mixed with ester oils to pass through. Alternatively, the resultant adsorption/absorption media is disposed into a fabric and formed as a wall used to enclose oil-filled equipment. The media adsorbs/absorbs the ester oils from the liquid, while allowing the liquid to disperse and pass through.
