摘要:
There is provided a method for treating a surface comprising heating the object and the object with a solution comprising a thermal initiator and a polymerizable molecule, wherein the polymerizable molecule reacts with the surface and forms a covalent bond and optionally a covalently bound polymer on the surface of the object. Metal ions are bound to the surface to make the surface possible for adding further metal later. Advantages include that complicated geometries can be coated, problems with oxygen inhibition of the initiator is reduced, and surface reaction to form covalent bonds is promoted compared to the bulk polymerization reaction.
摘要:
A copolymer is formed by contacting an olefin and a 1,1-dicarbonyl substituted alkene and reacting the olefin and 1,1-dicarbonyl substituted alkene under a pressure greater than atmospheric pressure in the presence of a free radical initiator. The copolymer may be useful for packaging films and may be used in the absence of compatibilizers in combination with other plastics such as in laminate structures (films having at least two layers). The polymers may also improve the recyclability and biodegradability of polyolefins such as polyethylene and polypropylene.

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.
