Abstract: Disclosed are a green synthesis method of an antibacterial super-porous hydrogel, a product of the antibacterial super-porous hydrogel and an application of the antibacterial super-porous hydrogel to degradation of various pollutants in wastewater treatment. The super-porous hydrogel based on poly (ionic liquid) is prepared by copolymerization of an imidazole type ionic liquid with double bonds and polyethylene glycol diacrylate (PEGDA) as a cross-linker. In the reaction system, water is a good solvent for the monomer ionic liquid and PEGDA, but a poor solvent for the poly (ionic liquid); when an initial concentration of the ionic liquid is higher than 25%, the phase separation typically proceeds through poly(ionic liquid) formation, interconnected networks with macroporous structure could be obtained by photo-crosslinking.

Abstract: The present invention relates to articles comprising crosslinked polymer network comprising thioether crosslinks and process of making and using same. Such thiol-ene crosslinking reactions not only make the isocyanate crosslinking reaction unnecessary, but they also improve the article's strength due to chemical crosslinking between the article's resin layers, and reduce or eliminate post curing. Thus resulting in a sufficiently cured article in a much shorter time.

Abstract: Liquid radiation curable compositions are disclosed which are suitable for hybrid (i.e. cationic and free-radical) polymerization when processed via additive fabrication equipment utilizing sources of actinic radiation with peak spectral intensities in the UV/vis region. According to one aspect, the compositions possess a first photoinitiator that is an iodonium salt of a non-fluorinated borate anion. According to another aspect, the composition is substantially devoid of a Norrish Type I and/or Type II photoinitiator. Also disclosed are methods of creating three-dimensional parts via additive fabrication processes utilizing sources of actinic radiation with peak spectral intensities in the UV/vis region employing liquid radiation curable compositions suitable for hybrid polymerization, and the parts cured therefrom.
