Abstract In this study, we prepared a series of tung oil phenolic foams (TPF) by a
one-pot method. The FT-IR and 1
H NMR spectra confirm the successful FriedelCrafts grafting of phenol to the long-chain alkyl group in tung oil. Modified TPFs
exhibit enhanced mechanical properties, including compressive and flexural
strengths of up to 0.278 ± 0.036 MPa and 0.450 ± 0.017 MPa, respectively, which
represent increases of 68.75% and 86.72% over those of pure phenolic foam (PF).
SEM spectra reveal the TPF microstructure to have uniform hexagonal cell morphology, narrower cell size distribution, and smaller More >
