Preparation and flame retardancy of an intumescent flame-retardant epoxy resin system constructed by multiple flame-retardant compositions containing phosphorus and nitrogen heterocycle

, 2015
A phosphorous/nitrogen-containing reactive phenolic derivative (DOPO-HPM) was synthesized via the addition reaction between 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and N-(4-hydroxyphenyl) maleimide (HPM).

Ionic Liquid (IL) Compatibilization of Macropore‐Infused Nanocomposite Emulsion Thermosets (MINETs) for Structural Ion Transport

Advanced Materials Interfaces, EarlyView.
Macropore‐infused nanocomposite emulsion thermosets (MINETs) offer tunable multifunctionality due to their incorporation of structural resin, functional nanoparticles, and working fluid stabilized by surfactant. Here we show that if ionic liquid working fluids are introduced, structural capacitive (conductive particles) or separator (insulating ...

In Situ Generation of Gel Foam via Heat‐Accelerated Calcium Ion Release From Nano‐CaCO3 for Lithium‐Ion Battery Fire Suppression and Prevention

Advanced Science, EarlyView.
We present a heat‐accelerated in situ crosslinking strategy to create an alginate gel foam for lithium‐ion battery fire suppression. At ambient temperature, the formulation maintains low viscosity for easy foam generation. After exposure to fire, δ‐gluconolactone hydrolysis accelerates, enabling rapid Ca2+ release from CaCO3 and rapid ionic ...
