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: The disclosure provides reversible polymers from polyurea by modifying the nitrogen atom with hindered substituents. The reversibility of hindered urea bond (HUB) can be controlled by changing the bulkiness of the substituents, and N-tert-butyl-N-ethylurea (TBEU), with its high binding constant and short lifetime, is applicable in the design of reversible polymer and self-healing materials at mild temperatures without external stimuli. HUB can be used in the design of smart materials with its adjustable reversibility, facile synthesis, and compatibility with many other polymer structures.
