Design and synthesis of anhydride-terminated imide oligomer containing phosphorus and fluorine for high-performance flame-retarded epoxy resins

Poly(silylene arylacetylene)s containing hexafluoroisopropylidene with attractive mechanical properties and dielectric performance for wave-transparent composites

“…With increasing the frequency, the dipole orientation cannot keep up with the change of alternating electric field, in favor of further decreasing the ε of the cured resins. 36 The dielectric properties of PFSA-C and PTFOSA-C are better than those of reported polymer matrices of wave-transparent composites, such as cyanate resins, 30,37 epoxy resins, 38,39 bismaleimide resins, 40,41 polyimide resins 42,43 and other poly(silylene arylacetylene)s. 19,28 The dielectric properties of PFSA-C and PTFOSA-C as compared with those of the reported resins along with their T d5 are shown in Fig. 5b.…”

Uniformly-Dispersed Black Phosphorene as Flame-Retardant Epoxy Composites via Iterative Dispersion Strategy

“…This phosphorus-containing radicals are excellent quenchers of the free radical chain reaction. 38 In addition, phosphorus-containing groups are also decomposed into combustible gases to dilute combustible gases. 39 These multiple effects result in rapid suppression of the combustion behavior.…”

Synthesis of Phosphorus- and Fluorine-Containing Hyperbranched Imide Oligomers for Flame-Retardant Epoxy Thermosets

“…14,15 Our group has prepared epoxy thermosets modified by a linear anhydride-end-capped imide oligomer with DOPO, triazine, and trifluoromethyl groups. 16 Significant improvements in both flame retardancy and heat resistance were observed, the former being attributed to the good charring ability of DOPO, triazine, and imide groups, and the latter to the rigid aromatic imide structures. the dielectric properties of the modified epoxy thermosets were improved by the low-polarity trifluoromethyl groups.…”
