Methods for post-processing photofabricated articles created via additive fabrication processes are described and claimed herein. Such methods include providing a photofabricated article, preferably an article that has been at least partially cured via cationic polymerization mechanisms, optionally, post-processing the photofabricated article, and base-washing the photofabricated article in an alkaline solution or dispersion to create a neutralized photofabricated article. In another embodiment, the methods include treating a photofabricated article having a residual acid or base species with a treatment composition in order to create a neutralized photofabricated article. Also described and claimed are the neutralized photofabricated articles created via the methods herein elsewhere described. Such articles are preferably biocompatible, especially as determined by their lack of cytotoxicity potential.

The present invention pertains to blends of crosslinkable vinylidene fluoride copolymers comprising recurring units derived from hydrophilic monomers, said blend being useful for producing shaped articles characterized by improved performances.

The invention relates to a method for modifying an object comprising the step of: I) providing an object which is made at least partially of a construction material comprising a thermoplastic polyurethane. The method also comprises the following steps: II) contacting, at least in part, the construction material, for a first predetermined period of time, with a first liquid comprising ≥80% by weight, based on the total weight of the first liquid, of a polar aprotic solvent; III) contacting, for a second predetermined period of time, the areas of the construction material that were in contact with the liquid in step II) with a second liquid comprising ≥80% by weight, based on the total weight of the second liquid, of a polar protic solvent. Preferably, the first liquid is DMSO or acetone and the second liquid is water.

A padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), has a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The padding device is formed by injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system and a respirator with the carrying belt system are provided with the belt system having the padding device.

A method of forming nanoparticles having superhydrophobicity includes preparing a PDMS film including a structure having a predetermined shape on a surface thereof, and generating the nanoparticles having superhydrophobicity on the surface of the PDMS film by combusting the surface of the PDMS film using a diffusion flame. Transparent nanoparticles having superhydrophobicity and oleophobicity may be generated simply and easily on the surface of the PDMS film.

A material susceptible to dielectric heating has a base polymeric thermoplastic material (1) and a dielectric heating susceptor (2, 3) which increases susceptibility to heating by irradiation with electromagnetic, for example RF or microwave, radiation. The dielectric heating susceptor has a polymeric material (2) such as PVDF which is different from the base polymeric material and has a higher dielectric loss factor than the base polymeric material. The dielectric heating susceptor also comprises electrically polarisable entities such as carbon black dispersed within the base polymeric material without forming a conductive network. The two susceptor materials in combination with the base polymer are particularly effective together at improving susceptibility to electromagnetic radiation heating of the whole material.

One aspect of the present disclosure relates to a tissue integration device. The tissue integration device can be produced by forming a polymer mixture into a shape. The polymer mixture can include a polymer resin and a growth-promoting medium. Next, at least one polymer forming the polymer resin can be oriented in at least one direction. The shaped polymeric material can then be formed into the tissue integration device.
