A method of making an ink for use in additive manufacturing of a self-healable and shape-memorizable product includes mixing a diol with isophorone diisocyanate, dimethylacetamide, and dibutyltin dilaurate to form a first solution. The method further includes mixing the first solution with 2-Hydroxyethyl disulfide to form a second solution. The method further includes mixing the second solution with 2-Hydroxyethyl methacrylate to form a third solution. The method further includes mixing the third solution with a tributylphosphine, a photoinitiator, and a photoabsorber to facilitate additive manufacturing of the ink.

Tumor resection is commonly practiced to prevent the progression of cancer. However, there are post-surgery concerns including the formation of a void that can allow cancer cells to escape at the surgery site, which increases the risk of metastasis. To counter this challenge, an embodiment includes a polyurethane-based shape memory foam as a tissue void-filling device that can also release anti-cancer drugs. Such foams may activate at body temperature and become malleable. Such properties may enable the foam to be shaped to precisely seal the tissue void and then serve as a drug-eluting device. Based on the drug composition with poly vinyl alcohol (PVA), the drug release profile from the foam may be altered depending on the application.

The present disclosure is in the field of polymers and pharmaceuticals/antimicrobials. The disclosure provides compounds based on SNAP (synthetic novel antimicrobial polymer) technology, compositions and methods of managing microbial infections including surgical site infections (SSIs). The present compounds are used as a management/therapeutic strategy to target microbial infections and have advantages including excellent antimicrobial potency, biofilm disruption ability, broad spectrum activity against various organisms covering both gram negative and gram positive bacteria as well as fungal pathogens, and low toxicity profile to ensure a healthy therapeutic window for use in humans.

The present invention is directed to a phosphated epoxy resin comprising at least one terminal group comprising a phosphorous atom covalently bonded to the resin by a carbon-phosphorous bond or by a phosphoester linkage; and at least one carbamate functional group. The present invention is also directed towards aqueous resinous dispersions comprising the phosphated epoxy resin, methods of coating a substrate, coated substrates, and methods of making a phosphated epoxy resin.

The invention relates to a crosslinkable fluorinated urethane compound having at least one ethylenically unsaturated functional group. Such compounds are useful as coatings additives such that, when the coating is applied to a substrate, the additive compound is allowed to first migrate to the surface and subsequently crosslink to form a durable oil-, dirt-, and water-repellent surface.
