Functionalization of layered double hydroxides by intumescent flame retardant: Preparation, characterization, and application in ethylene vinyl acetate copolymer

Graphite-like carbon nitride and functionalized layered double hydroxide filled polypropylene-grafted maleic anhydride nanocomposites: Comparison in flame retardancy, and thermal, mechanical and UV-shielding properties

“…The LDH-B was fabricated using a modified aqueous miscible organic solvent treatment method [15]. The LDH-B was initially crystallized by dropwise adding a 50 mL aqueous solution containing 0.0375 mol of Zn(NO 3 ) 2 $6H 2 O and 0.0187 mol of Al(NO 3 ) 3 $9H 2 O into a 50 mL of 1.7 M H 3 BO 3 aqueous solution.…”

“…Yao and Shu [12,13] prepared the biologically inspired LDH based polymer nanocomposite films with superior mechanical and optical properties. Huang et al [14,15] reported polymer/LDHs nanocomposites combining graphene and intumescent flame retardant, for improved thermal stability and fire retardancy. Wang's group [1,2,16e22] fabricated a variety of modified LDHs and systemically studied their application in polymeric materials.…”

Ammonium alcohol polyvinyl phosphate intercalated LDHs/epoxy nanocomposites

“…As a polar polymer, PVA has been modified by LDHs to promote the thermal, morphological and mechanical properties via the interaction between the PVA and the LDHs by hydrogen bonding through hydroxyl groups [10][11][12]. PVA also showed good compatibility with ammonium dihydrogen phosphate (NH 4 H 2 PO 4 , ADP) [13] and synergistic flame retardancy with ammonium polyphosphate (APP)/LDHs [14]. Because of the reaction between the amine groups of the intercalated amino compound and the epoxy groups, the adhesion between the LDHs nanolayers and epoxy molecules makes these LDHs/epoxy nanocomposites more compatible.…”

Phosphorus-containing flame retardant modified layered double hydroxides and their applications on polylactide film with good transparency

“…Therefore, how to improve the flame retardant efficiency at low LDH loading seems to be a challenging work [21,22,28]. And the use of some synergistic components to obtain high flame retardant effect shows to be a successful strategy [8,29,30]. For example, the synergistic effect between melamine and LDH was studied in ethylene-vinyl acetate (EVA) system.…”
