Design and Synthesis of Shape Memory Phenol-Formaldehyde with Good Irradiation Resistance, Thermal, and Mechanical Properties

Abstract: Phenol-formaldehyde (PF) resins with low flammability and excellent ablative property have been widely used in thermal protection systems in the aerospace field. The developing deployable thermal protection structure has prompted further exploration of the possibility of PF resin as a smart polymer. This paper prepares the shape memory phenol-formaldehyde resins (SMPFs) by introducing polyurethane (PU) prepolymer into the resol resin. The SMPFs with crystallization microregion possess excellent shape memory pe… Show more

“…Zhou et al [ 26 ] toughened and modified the epoxy resin using a rubber copolymer, which improved the tensile and flexural properties, but the heat resistance of the system was reduced. There is a study that successfully prepared shape memory phenolic resins by introducing different contents of polyurethane prepolymers into phenolic resins [ 27 ]. With the increase of polyurethane prepolymer content, the elongation of the modified phenolic resin gradually increased, and the cured phenolic resin foam had a certain degree of toughness.…”
