However, the widely used polyethers suffer from low ionic conductivity at ambient temperature and unstable electrode–electrolyte interfaces. In this work, we systematically investigate the reactivities with metallic lithium of three carbonyl-containing polymer-based SPE hosts─a polyketone (POHM), a polyester (PCL), and a polycarbonate (PTeMC)─as potential alternatives to polyethers by means of DFT calculations and AIMD simulations. Our redox potential and frontier orbital analyses indicate that introducing alkoxy oxygens connected to carbonyl groups enhances the electrochemical stability of polyester and polycarbonate, but also increases their reactivity on the Li anode surface. In particular, PTeMC shows higher electron uptake and a lower conduction band when interacting with surface Li. This increased reactivity, however, may also promote the formation of a stable solid electrolyte interphase (SEI), preventing further reduction of the electrolyte. We further summarize the possible decomposition mechanisms of the SPE polymer host and predict the resulting SEI components. The simulations revealed that POHM predominantly undergoes α-dehydrogenation and nucleophilic addition–elimination reactions, while PCL exhibits C_carbonyl–O_alkoxy bond cleavage, producing both saturated and unsaturated lithium alkoxides. In the case of PTeMC, breaking two C_carbonyl–O_alkoxy bonds can generate two saturated lithium alkoxides and a Li_<i>x</i>CO species, or it can produce a RCO₃Li species and unsaturated hydrocarbons via a C_alkoxy–O_alkoxy bond cleavage; these pathways are kinetically favorable and unfavorable, respectively.

However, the low stretchability and adhesion, poor self-healing, and wire transmission remain the major issues that limit the applications of poly(LA)-based gel sensors. It is urgent to develop multifunctional biogels with excellent comprehensive performance. In this work, multifunctional conductive poly(LA)-based zwitterionic biogels (denoted as PLLS gels) were fabricated by introducing hydrophilic sulfobetaine methacrylate (SBMA) through nucleophilic addition reactions with poly(LA). The addition of SBMA endowed the gels with conductivity due to the abundant anionic and cationic groups of the zwitterionic structure. The excellent biocompatibility of poly(LA) and SBMA provided the gels nontoxicity and harmlessness. As expected, the PLLS gels possessed high stretchability, adhesion, and self-healing due to the multiple dynamic bonds, including hydrogen bonds and electrostatic interactions. Besides, the gels exhibited excellent biodegradability, antioxidant, and antibacterial activities. The PLLS gels had found application as a wireless wearable sensor, which could monitor various human activities involving temperature changes, human joint movements, and voice recognition.

Unfortunately, the development of high-performance COFs remains challenging because of their narrow absorption bandwidth, rapid electron–hole separation or recombination, and other limitations. Herein, a polyethylene glycol (PEG) engineering strategy is developed to construct high-efficiency photocontrol oxidase (OXD) mimics based on COFs. A series of COFs with PEG side chains were synthesized through the condensation of an N-containing aldehyde ligand (TPY) with PEGylated amine ligands, which were decorated with PEG chains of different lengths. By introducing PEG chains, the electron–hole recombination of COFs can be slowed down, while electron–hole separation is accelerated; meanwhile, the affinity between COFs and the substrate can be enhanced, thereby improving the photoactive OXD-like activity of COFs. The N atom in TPY induces a red shift in the band-edge absorption of COFs and reduces the band gap, further improving their light absorption performance. Notably, COF-TPY-4O exhibited greater activity than other COFs. As a proof of concept, COF-TPY-4O was used for the construction of biosensors and elimination of bacteria, demonstrating its potential as a photoactive nanozyme with good application prospects.

However, introducing flexible structures reduces the glass transition temperature (<i>T</i>_g) and mechanical strength, and importantly, the gas barrier properties of most PETGs are weak. Here, a series of poly(terephthalic acid-naphthalene dicarboxylic acid-ethylene glycol-neopentyl glycol) (PENTN) were prepared by melt polymerization using different contents of 1,4-naphthalene dicarboxylic acid (1,4-NDA) or 2,6-naphthalene dicarboxylic acid (2,6-NDA).
