A nitrogen-rich, azaindole-based microporous organic network: synergistic effect of local dipole–π and dipole–quadrupole interactions on carbon dioxide uptake
关键字：microporous organic polymer, dipole–π and dipole–quadrupole interactions
A new type of microporous organic polymer with azaindole units (N-PEINK) has been designed. The resulting N-PEINK exhibits good chemical and thermal stability with a decomposition temperature of 550 °C. Taking advantage of the synergistic effect of local dipole–π and dipole–quadrupole interactions between azaindole and carbon dioxide (CO2), the CO2 uptake capacity of the polymer reaches 20.8...

Formation of plasticized polyvinyl butyral-zirconia hybrid films and their application to laminated glass
关键字：plasticized Poly (vinyl butyral); zirconium dioxide; laminated Glass; sol–gel process; thermal/mechanical properties
Poly(vinyl butyral)(PVB) is widely used as the film sandwiched in the laminated glass owing to its merits,such as sturdiness, flexibility and great adhesiveness with glass as well as the high impact strength at low temperature.&nb...

Carbon Dioxide/Epoxide Copolymerization via a Nanosized Zinc–Cobalt (III) Double Metal Cyanide Complex: Substituent Effects of Epoxides on Polycarbonate Selectivity, Regioselectivity and Glass Transition Temperatures
In this study, we describe the substituent effect of epoxides on CO2/epoxide copolymerization catalyzed by a nanosized zinc?cobalt(III) double metal cyanide complex [Zn?Co(III) DMCC]. The Zn?Co(III) DMCC catalyzed the
copolymerization of CO2 with 11 epoxides with alkyl or aryl groups at 50?60 °C within 15 h. The reaction afforded various CO2/epoxide copolymers with high epoxide&nbs...

Poly(L-lactic acid)/silicone dioxide nanocomposites prepared via in situ melt polycondensation of L-lactic acid in the presence of acidic silica sol: Dispersion stability of nanoparticles during dehydration/oligomerization.
In this work, the stability of nanoparticles
during the dehydration/oligomerization (D/O) stage in
situ melt polycondensation of L-lactic acid to prepare
poly(L-lactic acid) (PLLA)/SiO2 nanocomposite was studied.
The change in the appearance of the reaction mixture
was tracked, and the resultant oligo(L-lactic acid) (OLLA)/
SiO2 and PLLA/SiO2 nanocomposites were characterized
by transmissio...

Poly(L-Lactic Acid)/Silicon Dioxide Nanocomposite Prepared Via the In Situ Melt Polycondensation of L-Lactic Acid in the Presence of Acidic Silica Sol: Isothermal Crystallization and Melting Behaviors
In a previous article, we reported the preparation
and characterization of a nanocomposite of poly(Llactic
acid) (PLLA) and silica via the in situ melt polymerization
of L-lactic acid in the presence of acidic silica sol.
In this study, the isothermal crystallization and melting
behaviors of a PLLA/silicon dioxide (SiO2) nanocomposite
with 5 wt % well-dispersed SiO2 nanoparticles (PLLASN5)
