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 mean cell size, suggesting
enhanced… More >
