Hyperbranched polymers containing epoxy and imide structure

A challenge to polymer scientists is to design new materials with superior overall performance in heat-resistance, cold-resistance, strength, and toughness. Here we report the synthesis of hyperbranched polymers containing epoxy and imide structure (EHPI-n, n = 6, 12, and 24) with various molecular weights and degrees of branching using a new synthetic diimide dicarboxylic acid. EHPI-n significantly decreases the gelation time and accelerates the curing of EHPI-n/diglycidyl ether of bisphenol-A (DGEBA). Both EHPI-6 and EHPI-12 significantly reduce the viscosity, activation energy, and average particle size of EHPI-n/DGEBA blends due to the disentangling function and compatibility of the EHPI-n. The toughness property, including elongation at break, impact strength, critical strain energy value (G(IC)) and critical stress intensity factor (K-IC) of 12 wt % EHPI-12/DGEBA composites are improved over the neat DGEBA, by 144.72 %, 197.9 %, 168.4 % and 72.6 %, respectively, while their mechanical properties, including tensile strength, storage modulus and flexural strength are enhanced by 61.2 %, 89.9 %, 44.2 %. The heat-resistant index and beta-relaxation peak temperatures of the composites are improved 14 degrees C and 15 degrees C, respectively, indicating both outstanding high-temperature resistance and outstanding low-temperature resistance. The simultaneous improvement on multiple performances is attributable to an in-situ homogeneous reinforcing and toughening mechanism, which is explained by free volume fraction, microstructure and surface micrograph. The EHPI-n present great potential as advanced materials for aerospace and wind turbine.

Superacid sulfated SnO2 doped with CeO2: A novel inorganic filler to simultaneously enhance conductivity and stabilities of proton exchange membrane

Towards the breaking of the trade-off’ between proton conductivity and stabilities of sulfonated poly(aryl ether sulfone) (SPAES)-based proton exchange membranes, a strategy of compositing with the superacids of sulfated SnO2 (ST) and SnO2-xCeO(2) (CSTx) is designed and carried out. The superacids of ST and CSTx have been synthesized by sulfonation of SnO2 with sulfuric acid and subsequently doped with CeO2. By the solution casting approach, the composite membranes are obtained in a homogenous state and show excellent mechanical strength, thermal, dimensional and chemical stability. ST or CSTx in the composite membranes provides excess active sites and forms additional proton-conducting channels by a network of hydrogen bonds. Although with low IEC levels, all the composite membranes show larger water absorption and proton conductivity than the control SPAES membrane. As a result, the SPAES-2C5T3 membrane achieves a power output of 673.6 mW/cm(2) at 80 degrees C, which is higher than the control membrane (481.8 mW/cm(2)). The durability of the SPAES-2C5T3 membrane under accelerated stress test conditions is significantly enhanced compared to the control SPAES membrane, and the aged SPAES-2C5T3 membrane exhibits lower hydrogen crossover and better cell performance than the aged control SPAES membrane.

A mechanically robust self-healing binder for silicon anode in lithium ion batteries

Both industrious and academic research societies have considered silicon (Si) as the most promising anode for next-generation lithium ion batteries (LIBs) because silicon offers more than one order of magnitude higher capacity than conventional anode materials. However, huge volume changes and pulverization of the silicon particles during the charge/discharge processes damage the longevity of Si-based LIBs. Self-healing binders could tackle this problem by in-situ repairing the damage to the silicon anode. Herein, we synthesized a novel selfhealing poly(ether-thioureas) (SHPET) polymer with balanced rigidity and softness for the silicon anode. The as-prepared silicon anode with the self-healing binder exhibits excellent structural stability and superior electrochemical performance, delivering a high discharge capacity of 3744 mAh g(-1) at a current density of 420 mA g(-1), and achieving a stable cycle life with a high capacity retention of 85.6% after 250 cycles at a high current rate of 4200 mA g(-1). The success of this work suggests that the proposed SHPET binder facilitates fast self-healing, buffers the drastic volume changes and overcomes the mechanical strain in the course of the charge/discharge process, and could subsequently accelerate the commercialization of the silicon anode.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 101-55-3. Quality Control of 1-Bromo-4-phenoxybenzene.
