Abstract: A porous composition comprising a porous organic polymer (POP) fiber having a diameter of at least 100 nm and a length of at least 1 mm and pores having a size within a range of 10 nm to 5 microns distributed over the surface and volume of the POP fiber, wherein the organic polymer is insoluble in water and may be selected from, e.g., polyolefins, polyesters, polyamides, and polyacrylonitrile. Also described herein is a method for producing a POP fiber comprising: (i) forming a precursor fiber from a blend of an organic polymer and lignin, wherein the lignin is present in the form of domains within the precursor fiber; and (ii) washing the precursor fiber with a solvent that dissolves the lignin to result in the POP fiber. Also described herein is a method for removing oil from an oil-water mixture comprising contacting the oil-water mixture with the POP fibers.

Abstract: Methods of making fiber reinforced composite articles are described. The methods may include treating fibers with a sizing composition that includes a polymerization compound, and introducing the treated fibers to a pre-polymerized composition. The combination of the treated fibers and pre-polymerized composition may then undergo a temperature adjustment to a polymerization temperature at which the pre-polymerized composition polymerizes into a plastic around the fibers to form the fiber-reinforced composite article. Techniques for introducing the treated fibers to the pre-polymerized composition may include pultrusion, filament winding, reactive injection molding (RIM), structural reactive injection molding (SRIM), resin transfer molding (RTM), vacuum-assisted resin transfer molding (VARTM), long fiber injection (LFI), sheet molding compound (SMC) molding, bulk molding compound (BMC) molding, a spray-up application, and/or a hand lay-up application, among other techniques.
