Fig. 7From: Biodegradable, flame retardant wood-plastic combination via in situ ring-opening polymerization of lactide monomersTreated samples after conducting the UL-94 Flame Test, from left: 3 wood/PLA samples, 2 wood/resorcinol bis(diphenyl phosphate) (RDP) samples, and 2 wood/resorcinol bis(diphenyl phosphate) (RDP)/PLA samples. The minor discoloration at the top ends of the wood/resorcinol bis(diphenyl phosphate)(RDP)/PLA composites resulted from polymerization; it is unrelated to the flame testBack to article page
