A room-temperature self-healing polyurethane elastomer synthesised via optimized hierarchical H-bonding interactions ultimately exhibited a synchronous efficiency of more than 83% with tensile strength, elongation, and toughness.
The flow behaviour of AA2060 Al alloy under warm/hot deformation conditions is complicated because its dependency on strain rates (ε˙), (ε), and modes. Thus, it crucial to reveal predict the behaviours this at a wide range temperatures (T) ε˙ using different constitutive models. Firstly, isothermal tensile tests were carried out via Gleeble-3800 thermomechanical simulator T 100, 200, 300, 400, 500 °C 0.01, 0.1, 1, 10 s−1 sheet. Consequently, three phenomenological-based models (L-MJC,...
In order to explore new high-strength polymer materials that can achieve self-healing of damage under more mild conditions, the room temperature polyurethane elastomers with multiple hydrogen bonds/aromatic disulphide bonds (PU PIPMD ) were constructed by using strategy repair networks. Through interaction between carbamate group (-NH-C(=O)-O-), pyridine and urea (-NH-CO-NH-) form a different strength bond, reversible covalent bond-disulphide bond (-S-S-) was introduced into molecular chain...

In this study, with the sulfonate groups into PCE structure, its dispersion capacity absorbed amount are increased firstly then decreased, but retardation hydration effect is weakened gradually. The molecular weight,...

In this paper, a multi-passband microwave photonic filter (MPF) for sensing applications has been proposed and experimentally demonstrated. The principle is based on finite impulse response (FIR) filter. Multi passband can be achieved simply by cascading two Mach-Zehnder interferometers (MZIs) with different arm length difference. variation of the difference MZI will change free spectral range (FSR) optical spectrum, resulting in frequency passbands. Thus, changing using variable delay line...
