Abstract:
Polymers play a crucial role in our daily lives; however, achieving a balance among mechanical performance, resistance to high and low temperatures, and mild shaping remains challenging. Here, we report a water-triggered supramolecular polymer composed of cellulose and polymethyl methacrylate. Following water-induced transformation of a stretchable supramolecular network into a densified cross-linked domain, the resulting polymer exhibits a remarkable increase in tensile strength from 2.7 MPa to 61.7 MPa, representing more than a 22-fold enhancement, and a flexural strength of 97 MPa, while maintaining structural integrity across a temperature range of -196 °C to 200 °C. In addition, the polymer enables scalable water-mediated shaping and reinforcement even in seawater, surfactant wastewater, and dye wastewater, while retaining high mechanical performance. Economic analysis and recycling assessment demonstrate that this polymer is amenable to scalable production and has considerable market potential. This study provides a biomimetic formulation for the fabrication of high-performance supramolecular polymers and broadens their potential applications across diverse fields.

Polymer Classification: Crystallinity
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
