Construction of intumescent flame retardant and hydrophobic coating on wood substrates based on thiol-ene click chemistry without photoinitiators

Intumescent transparent coatings consisting of allyl-functionalized phosphonitrile (HABP), trimethylolpropane tris(3-mercaptopropionate) (TMMP) and 1H,1H,2H,2H-perfluorodecanethiol (PFDT) were prepared via photo-induced thiol-ene reactions without photoinitiator, and then fabricated onto wood surfaces to achieve both flame retardancy and hydrophobicity. The effects of PFDT content on the waterproof and fire prevention of the samples were...
