【61 Materials Chemistry Frontiers】 Simultaneously improving the mechanical properties and flame retardancy of polypropylene using functionalized carbon nanotubes by covalently wrapping flame retardant followed by linking polypropylene
The fabrication of polymer nanocomposites with improved physical and chemical properties is a hot topic in the fields of materials and chemistry. In this work, carbon nanotubes (CNTs) are functionalized through flame retardant wrapping and maleic anhydride polypropylene (PPMA) covalently attaching to achieve a compact char layer and strong interfacial adhesion. The resultant polypropylene (PP)/fun...

02 Catalyzing carbonization of poly(L-lactide) by nanosized carbon black combined with Ni2O3 for improving flame retardancy
关键字：poly(L-lactide)
Catalyzing the carbonization of a polymer itself to form a protective carbonaceous layer has attracted tremendous interest in the flame retardancy of polymers, but the efficiency of this strategy was largely limited to polymers containing heteroatoms within their backbone. In this study, a novel type of combined catalyst, consisting of nanosized carbon black (CB) and Ni2O3, was found to efficientl...

Thermal and flammability properties of polypropylene/carbon black nanocomposites
关键字：Carbon black, Flame retardancy, Nanocomposite, Polypropylene
Polypropylene/carbon black (PP/CB) nanocomposites were prepared by melt compounding to investigate the effect of nanofiller loadings on the thermal and flammability properties of PP. The obtained nanocomposites displayed not only dramatically enhanced thermal stability both under nitrogen and in air, but also improved flame retardancy to some extent. Moreover, the higher the loading level of CB,...
