Cross-linked polymers for gas separation have significant advantages in increasing selectivity and stability. However, the cross-linking strategies unavoidably form permanent interchain covalent bonds alter polymer packing state, which largely decrease solubility, static toughness, reprocessability. Herein, a secondary-amine-containing diamine (HCBDA) derived from carbazole is synthesized polymerized with 6FDA to furnish gas-permeable polyimide (HCB-PI) pseudo-cross-linked hydrogen-bonding...
Self-healing materials, which can autonomously repair damages like living organisms, have undergone extensive development in the last decades. The bottleneck problems for their practical applications are long healing time, inferior mechanical strength, and aging sensitivity. Here, a new class of polymeric materials rationally grafted with oligo poly(ethylene glycol) is reported. network based on formation multiple weak hydrogen bonds endows elastomers good comprehensive performances...
Rapid and accurate identification of moving load is crucial for bridge operation management early warning overload events. However, it hard to obtain them rapidly via traditional machine learning methods, due their massive model parameters complex network structure. To this end, paper proposes a novel method perform loads using MobileNetV2 transfer learning. Specifically, the dynamic responses vehicle–bridge interaction system are firstly transformed into two-dimensional time-frequency image...
This article investigates the out-of-plane buckling of functionally graded porous I-shaped circular arches with graphene platelets reinforcements in a uniform temperature field. The accurate expressions prebuckling internal forces owing to thermal expansion are derived. theoretical difference is obtained by Ritz technique and verified finite element results. Notably, asymmetrical distribution pores along height section, monosymmetry parameter considered energy equation. effects weight...
Highly transparent PI films with excellent mechanical strength, high heat-resistance and superior fracture toughness were fabricated.
The rigid V-shaped Tröger's base (TB) unit has been proven efficacious in creating microporosity, making TB-based polyimides (PIs) exhibiting significant advantages simultaneously increasing gas permeability and selectivity for the separation industry. However, PIs commonly display undesired mechanical performance due to low molecular weight resulting from evident steric hindrance reactivity of TB-containing diamines. Herein, a novel diamine-containing bisimide linkage (BIDA) synthesized...
Long-span continuous reinforced-concrete rigid-frame bridges are sensitive to the shrinkage and creep of concrete relaxation prestressing tendons have experienced problems related serviceability loss because excessive multidecade deflections. Moreover, large negative bending moment shear force in box girder near piers may lead cracks top slabs webs. To improve structural performance mitigate long-term deflection bridges, a novel type open-web bridge was developed during design Beipan River...
