Abstract Catalytic/initiated cracking of endothermic hydrocarbon fuels is an effective technology for cooling a hypersonic aircraft with high Mach number (over 5). Catalysts and initiators can promote fuel at low temperatures, increase conversion the heat sink capacity, suppress coke deposition, thereby reducing waste heat. mainly include metal oxide catalysts, noble catalysts nanoparticles, ze...

Vinyl-terminated hyperbranched poly(amido amine)s is obtained by Michael addition polymerization of 4-(aminomethyl)piperidine (AMPD) with a double molar N,N-cystaminebis(acrylamide) (BAC). Then an amphiphilic hyperbranched poly(BAC2-AMPD1)-PEG is produced via converting the vinyl groups to amines followed by PEGylation. Transmission electron microscopy (TEM), dynamic light scattering (DLS), and...

Linear and hyperbranched poly(azomethine)s (PAMs)-based on triphenylamine moieties are synthesized and used as the functioning layers in the Ta/PAM/Pt resistive switching memory devices. Comparably, the hyperbranched PAM with isotropic architecture and semi-crystalline nature shows enhanced memory behaviors with more uniform distribution of the HRS and LRS resistances.

Hyperbranched polymers were prepared from a variety of monoand difunctional monomers and used in the development of novel UV-imprint lithography (UV-IL) resists. The unique physical and chemical properties of these hyperbranched materials significantly increase the range of molecular systems that could be imprinted. Traditional challenges, such as the use of monomers that have low boiling point...

Branched thermotropic liquid crystals were successfully obtained from ionic interactions between hyperbranched polyamidoamine and sodium dodecylsulfate. These complexes present columnar rectangular and lamellar thermotropic mesophases as demonstrated by polarized optical microscopy, differential scanning calorimetry, and small-angle X-ray scattering. The relationships between the structural cha...

As a kind of promising drug carriers, smart polymers have attracted much attention due to the effective and controlled release in target cells. Herein, reactive oxygen species (ROS)-responsive thioether-containing amphiphilic hyperbranched polymer prepared from MTPA TMPTGE (HBPMT) is synthesized 3-(methylthio)propylamine (MTPA) trimethylolpropane triglycidyl ether (TMPTGE) by amine-epoxy click ...
