Advanced Flame Retardant Materials

Abstract

Degradable, flame retardant, and flexible nanocomposite films with low dielectric constant were prepared with poly (lactic acid) (PLA), nano ZIF-8@GO, and degradable flame-retardant resorcinol di(phenyl phosphate) (RDP). The SEM results of the fractured surfaces indicated that ZIF-8@GO and RDP were dispersed uniformly in the PLA matrix. The prepared films had good mechanical properties and the tensile strength of the film with 1.5 wt% of ZIF-8@GO was increased to 48.2 MPa, compared with 38.5 MPa of pure PLA. Meanwhile, the nanocomposite films were flexible due to the toughing effect of RDP. Moreover, above 27.0% of limited oxygen index (LOI) and a VTM-0 rating were achieved for the nanocomposite films. The effects of nano ZIF-8@GO hybrids and RDP on the dielectric properties were investigated, and the results showed that ZIF-8@GO and RDP were beneficial in reducing the dielectric constant and dielectric loss of the nanocomposites.

Controlled high temperature stability of microwave plasma synthesized graphene nanosheets

“…Furthermore, the foam-like carbon structures are of high interest in energy storage applications such as supercapacitors and lithium-ion batteries [10]. High temperature stability under inert or oxidation atmosphere plays a key role in these future key enabling technologies applied to electric transport, flexible electronics and smart building and textile materials [11,12].…”
