摘要： The presently disclosed subject matter provides a scalable and electrostretching approach for generating microfibers exhibiting uniaxial alignment from polymer solutions. Such microfibers can be generated from a variety of natural polymers or synthetic polymers. The hydrogel microfibers can be used for controlled release of bioactive agents. The internal uniaxial alignment exhibited by the presently disclosed fibers provides improved mechanical properties to microfibers, contact guidance cues and induces alignment for cells seeded on or within the microfibers.

摘要： A polyolefin composition comprising a discontinuous polymer phase dispersed in a continuous polyolefin phase is disclosed. The discontinuous polymer is polymerized by a method comprising reacting a blend or mixture of the polyolefin and one or more polyethylenically unsaturated monomers in the presence of a free radical initiator. Articles and materials made from he composition exhibit several advantageous properties as compared to the corresponding unmodified polyolefins, for example printability, paintability, and dyeability in the case of spun fiber, sheets, automotive applications such as interior parts and bumpers; toughness and abrasion resistance in the case of flooring, and impact strength in the case of siding.

摘要： Self-reinforced composites of amorphous thermoplastic materials such as poly(methylmethacrylate), polycarbonate and polysulfone are made by melt-extruding and simultaneously drawing and cooling the material to produce fibers with longitudinally-oriented molecular chains, then arranging the fibers in a preform, such as a mat, rod, plate or other useful shape, in which adjacent fibers are in contact with each other, and thereafter heating the preform with fiber constraint to a temperature above the glass transition temperature and below the degradation temperature of the thermoplastic, and applying pressure, to soften and fuse together the outer surfaces of the fibers without completely eliminating the longitudinal orientation of the molecules within the fibers. Where the amorphous thermoplastic is poly(methylmethacrylate), the preform may be wrapped about the bone-implantable element of a joint prosthesis to provide a high-strength integrated mantle of connected, contracted, and oriented fibers. Upon implantation of the element in the intramedullary cavity of a bone, the surface of the self-reinforced mantle of sintered fibers may then bond chemically with a grouting of conventional poly(methylmethacrylate) bone cement.
