When increasing the addition of epoxy resin into polyurethane, two networks of the PU/ER IPNFs became miscible because of the reaction of the NCO group in PU network and OH group in ER network, which resulted in better compressive property of PU/ER IPNFs and thicker foam-wall comparing with neat polyurethane.展开更多
文摘Rigid polyurethane/epoxy resin interpenetrating polymer network foams were synthesized by one-step way. When increasing the addition of epoxy resin into polyurethane, two networks of the PU/ER IPNFs became miscible because of the reaction of the NCO group in PU network and OH group in ER network, which resulted in better compressive property of PU/ER IPNFs and thicker foam-wall comparing with neat polyurethane.
