Highly Cross-linked Epoxy Coating for Barring Organophosphate Chemical Warfare Agent Permeation

“…It is known that DMMP is a good halogen bond acceptor due to the chemical portion of −PO and −P−O− bonds. 26 There may exist a halogen bond 31 interaction between the trifluoromethyl group (−CF 3 ) and phosphate esters, probably resulting in a stronger interaction and higher adsorption between DMMP and F-EP. So, because of the lower free-volume hole size and weaker physical interaction with DMMP, EP has an advantage as a polymer coating material resistant to organophosphate compounds over F-EP.…”

“…29 On the other hand, working as a halogen bond (XB) acceptor, the oxygen of the phosphate ester of OPs also has strong interaction with halogens (F, Cl, Br, I) and other XB donors. 30,31 As a result, once they permeate into the polymer coating, it is difficult to decontaminate them. These facts represent a considerable challenge and demand for developing an impermeable polymer coating against OPs.…”
