The aging performance of bio‐oil phenol‐formaldehyde (BPF) resin was investigated using artificial accelerated aging method. After the treatment, the variations on the mass and bonding strength of plywood with BPF resin were determined. The changes in the microstructure, functional groups, and chemical bonds of adhesive films with BPF resin were also analyzed by scanning electron microscope, Fourier transform infrared spectroscopy, and X‐ray photoelectron spectroscopy analysis. The decrease of mass loss and bonding strength of BPF resin were smaller, the surface of BPF resin was smoother, and the amounts of CH2 groups and COC groups of BPF resin were larger than that of phenol‐formaldehyde (PF) resin at the same aged period. These results indicated that the bio‐oil could be used to improve the aging performance of PF resin. POLYM. ENG. SCI., 58:1810–1816, 2018. © 2017 Society of Plastics Engineers

Activated carbon monoliths (ACMs) were fabricated by H2O activation using powdered fast pyrolytic char (PFPC) as a raw material and bio-oil phenol-formaldehyde (BPF) resin as a binder. The effects of the ratio of BPF resin to PFPC on textural and chemical-surface properties of the ACMs were investigated using elemental analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and field-emission scanning electron microscopy (FE-SEM). The adsorption capacity and mechanical properties under different conditions were examined by N2 adsorption analysis and compression strength, respectively. The results indicated that the optimal ratio was 20 wt.% BPF resin binder. The compression strength of ACMs with a carbon content of 79.7 wt.% reached 3.74 MPa, while the BET surface area and total pore volume were 731.3 m2/g and 0.589 cm3/g, respectively. ACMs appeared to be mainly mesoporous with low graphitization and contained multiple functional groups such as alkyl, esters, ether, phenol, olefin, etc.
