Abstract: Clickable waterborne polymers, click crosslinking of waterborne polymers, click crosslinked waterborne polymers, clickable functional compounds, and click functionalized waterborne polymers are presented. For example, the waterborne polymers have pendant groups bearing alkyne and/or azide groups and alkyne. For example, the functionalized azide-containing functional compounds such as antimicrobial or infrared-refractive compounds. The click crosslinking of clickable waterborne polymers or polymer mixtures, and the click conjugation of clickable waterborne polymers with clickable functional compounds such as clickable antimicrobial or infrared-refractive compounds, which resulted in functional waterborne polymers with antimicrobial or infrared-refractive functions, are presented.

Abstract: In one aspect, the present disclosure relates to click-functional antimicrobial molecules (including small molecules or, in some cases, macromolecules) and the construction of antimicrobial polymers such as polyurethanes, polyesters, and polyacrylates, including through the use of such molecules. In some cases, the antimicrobial click-functional molecules are based on 1,2-benzisothiazolin-3-one (BIT), trimethylguanidine or tetramethylguanidine (TMG), polyhexamethylene guanidine (PHMG), fluorine-containing molecules, or a combination thereof. For example, 1,2-benzisothiazolin-3-one (BIT) functionalized with an alkyne (BIT-Al), trimethylguanidine or tetramethylguanidine (TMG) functioned with an alkyne (TMG-Al) or dual alkynes (TMG-dAl), and/or polyhexamethylene guanidine (PHMG) functionalized with an alkyne (PHMG-Al) are described herein. Clickable antimicrobial polymers can be used to form coatings or films.

Abstract: Embodiments provide a touch surface that can be integrated into an electronic device. User input can be received via the touch surface (e.g., a touchscreen, a key cap). The touch surface can include a substrate, a rigid layer for maintaining the contours of the substrate, and a surface layer deposited over the rigid layer for adjusting the surface energy of the touch surface. The substrate can be made with plastic; the rigid layer can be a diamond-like carbon (DLC) coating; and the surface layer can be comprised of fluoro- or silicon-rich molecules. The DLC can be deposited over the plastic substrate via physical vapor deposition (PVD) while the surface layer can be deposited over the DLC via a chemical vapor deposition (CVD). The touch surface can be constructed using different layers of material and using different methods to improve the longevity of the touch surface against repeated use and wear.
