Sustainable polycarbonate adhesives for dry and aqueous conditions with thermoresponsive properties

Abstract

Pressure sensitive adhesives are ubiquitous in commodity products such as tapes, bandages, labels, packaging, and insulation. With single use plastics comprising almost half of yearly plastic production, it is essential that the design, synthesis, and decomposition products of future materials, including polymer adhesives, are within the context of a healthy ecosystem along with comparable or superior performance to conventional materials. Here we show a series of sustainable polymeric adhesives, with an eco-design, that perform in both dry and wet environments. The terpolymerization of propylene oxide, glycidyl butyrate, and CO2, catalyzed by a cobalt salen complex bearing a quaternary ammonium salt, yields the poly(propylene-co-glycidyl butyrate carbonate)s (PPGBC)s. This polymeric adhesive system, composed of environmentally benign building blocks, implements carbon dioxide sequestration techniques, poses minimal environmental hazards, exhibits varied peel strengths from scotch tape to hot-melt wood-glue, and adheres to metal, glass, wood, and Teflon® surfaces.

Dendrites in Zn‐Based Batteries

“…This method accurately simulates the microprocess through which the dendrites pierce the interface layers. [ 260 ] These characterizations are intended to quantify profound interfacial interactions, such as Van der Waals forces, [ 261–263 ] topological adhesion, [ 264 ] and biomimetic microstructures, [ 265 ] which can trigger the dynamic contact‐oriented combination between artificial layers and Zn electrodes. Consequently, developing advanced characterization techniques to approximate diverse interfacial interactions will contribute to the rapid progress of Zn dendrite restraint.…”

Carbon dioxide copolymers: Emerging sustainable materials for versatile applications

“…The functional aliphatic polycarbonate containing hydroxyl group showed certain potential in biomedical materials such as drug release and tissue engineering 42 . Interestingly, Grinstaff and coworkers developed sustainable polycarbonate adhesives by terpolymerization of PO/glycidyl butyrate/CO 2 , which exhibited competitive adhesion ability in comparison with nondegradable commercial adhesives such as Scotch‐tape ® 125 …”

A Superstrong and Reversible Ionic Crystal‐Based Adhesive Inspired by Ice Adhesion

“…Further, traditional reversible adhesives can be fabricated from stimuli‐responsive polymers (e.g. temperature or light isomerization groups), [1a,c,d, 4] dynamic covalent bonds (e.g., Diels–Alder reaction, disulfide bonds), [5] phase or topology transitions [1d, 6] and reversible non‐covalent interactions (e.g., hydrogen bonds and host‐gust interactions) [4b, 5c, 7] . For instance, gecko‐inspired reversible adhesive suggests that well‐designed micro/nanoscale fibril structures are a powerful factor to induce the van der Waals interaction with the substrate [8] .…”
