A reforming device (1) is provided with, on one end side of a chamber (2), a gas supply part (3) and, on the other end side of the chamber (2), a gas discharge part (4). A support part (5) for supporting a porous material (10) is provided between the gas supply part (3) and the gas discharge part (4) inside the chamber (4). Then, the unsaturated hydrocarbon gas of an unsaturated hydrocarbon supply device (31) and the ozone gas of an ozone generation device (32) are supplied into the chamber (2) via the gas supply part (3) so as to reform the outer-peripheral-side surface and the inner side surface of the porous material (10) accommodated inside the chamber (2). The gas inside the chamber (2) is sucked by the gas discharge part (4) and discharged to the outside of the chamber (2).

A superhydrophobic modified film and modification method, and a triboelectric nanogenerator (TENG) composed thereof and a preparation method are disclosed. A polyethylene (PE) film is etched and deposited with an inductively coupled plasma (ICP) etcher in sequence. A nano-textured structure is formed on an upper surface of the PE film and a fluorocarbon layer is further deposited for modification. An upper electrode of the film is constructed by sticking a piece of ultra-thin copper tape on a superhydrophobic surface of the superhydrophobic modified film, and a lower electrode of the film is constructed by spin-coating a conductive polymer on a lower surface of the film after O.sub.2 plasma treatment. Thus, the TENG with high output and a double-electrode working mode based on the superhydrophobic modified greenhouse film is constructed. According to the modification method, the nano-textured structure is constructed on the surface of the film.

A method for producing a wear resistant polyethylene medical implant includes forming a medical implant, such as an orthopedic implant, made at least partially of ultra high molecular weight polyethylene (UHMWPE). The polyethylene may be irradiated with gamma ray or e-beam radiation to form free radicals and then crosslinked to eliminate free radicals prior to exposure to oxygen. The so treated bearing surface of the crosslinked polyethylene is then coated with a photoinitiator. Thereafter the bearing material is photocrosslinked with ultra-violet (UV) radiation. The photocrosslinking process can also be applied to non-crosslink UHMWPE.

A method for producing a polyolefin-based porous film includes an (A) step: a raw fabric forming step for forming a non-porous raw fabric from a polyolefin-based resin composition, a (B) step: an MD cold stretching step for cold stretching the non-porous raw fabric obtained in the (A) step at a temperature of −20° C. to (Tm−30)° C. (Tm is a melting point (° C.) of the non-porous raw fabric) in an extruding direction (MD) of the raw fabric to make the raw fabric porous; a (D) step: a TD cold stretching step for cold stretching a film processed in the (B) step in a direction (TD) perpendicular to the MD, and an (H) step: a thermal fixing step, in the above order.

A resin film containing a fluororesin as a main component has, on at least one surface thereof, a pre-treated surface having a content ratio of oxygen atoms or nitrogen atoms of 0.2 atomic percent or more. A coverlay includes the resin film and an adhesive layer laminated on the pre-treated surface. A substrate for a printed wiring board includes the resin film and a conductive layer laminated on the pre-treated surface. A printed wiring board includes an insulating base layer, a conductive pattern laminated on at least one surface of the base layer, and the coverlay for a printed wiring board, the coverlay being laminated on the conductive pattern.
