“…[32] For example, in recent researches, PET was first depolymerized into oligomers and further polymerized into upcycled thermoplastic polyester elastomer (TPEE) based on the approach of polymer-to-polymer upcycling. [33,34] TPEE, comprising different combinations in hard segments and soft segments, manifests high mechanical strength, strong elasticity, and solvent corrosion resistance. [35][36][37] Furthermore, upcycled TPEE has been fabricated into durable and flexible electrospun fibers, which presents superior mechanical properties than commercial TPEE.…”

Multiresponsive materials with reversible and durable characteristics are indispensable because of their promising applications in environmental change detections. To fabricate multiresponsive materials in mass production, however, complex reactions and impractical situations are often involved. Herein, a dual responsive (light and pH) spiropyran‐based smart sensor fabricated by a simple layer‐by‐layer (LbL) assembly process from upcycled thermoplastic polyester elastomer (TPEE) materials derived from recycled polyethylene terephthalate (r‐PET) is proposed. Positively charged chitosan solutions and negatively charged merocyanine‐COOH (MC‐COOH) solutions are employed in the LbL assembly technique, forming the chitosan‐spiropyran deposited TPEE (TPEE‐CH‐SP) film. Upon UV irradiation, the spiropyran‐COOH (SP‐COOH) molecules on the TPEE‐CH‐SP film undergo the ring‐opening isomerization, along with an apparent color change from colorless to purple, to transform into the MC‐COOH molecules. By further exposing the TPEE‐CH‐MC film to hydrogen chloride (HCl) and nitric acid (HNO3) vapors, the MC‐COOH molecules can be transformed into protonated merocyanine‐COOH (MCH‐COOH) with the simultaneous color change from purple to yellow.

“…HDA is generally considered safe, and it is used for preserving food and for producing medical plastic materials. [7][8][9][10] The free electron pairs of two amino groups in HDA easily coordinate various metal cations. [11][12][13] To our knowledge, the first HDA-based 3-dimensional framework, Cd(HDA)Ni-(CN 4 ), was synthesized in 1983 by Davies and Maver.…”
