Hydrogen bonding (HB) is vital for the phase transition and physical properties of stimuli responsive copolymers. However, governing mechanism remains unclear. Herein, we investigated HB dynamics in a representative thermo-responsive copolymer (PNIPAM-AM) aqueous solution. Three types were identified: polymer-polymer chain (CO:H–N), polymer chain-water molecule (CO:H–O) water-water (H–O:H–O) by vibrational spectroscopy. Increasing concentration, H–O:H–O softened CO:H–O stiffened, leading to...
Precise evaluation of the temperature and its evolution at microscopic scale in an operating electrochemical device is essential for accessing mechanism behind performance thermal management. However, such information limited, as most existing monitoring processes are carried out macroscale. Fluorescent nanodiamond (ND) enables sensitive nanoscale a working without perturbing processes. In this study, we demonstrated spatially resolved zinc (Zn) electroplating process, when fluctuation...
Thermal-responsive hydrogels are developed as ion-conductive switchs for energy storage devices, however, the molecule mechanism of switch on/off remains unclear. Here, poly(N-isopropylacrylamide-co-acrylamide) hydrogel is synthesized a model material and nanodiamond (ND) based quantum sensing phase change study developed. First, micro-scale separation with cross-linked mesh structure after sol-gel transition visualized in situ water molecules trapped by polymer chains on chemically "frozen"...
Peptide-based hydrogels form a kind of promising material broadly used in biomedicine and biotechnology. However, the correlation between their hydrogen bonding dynamics mechanical properties remains uncertain. In this study, we found that adoption β-sheet α-helix secondary structures by ECF-5 GFF-5 peptides, respectively, could further fiber networks to immobilize water molecules into hydrogels. Increasing peptide concentrations improvethe solidity these hydrogels, as evidenced higher...
