Composite films with polyurethane (PU), phenol formaldehyde resin (PFR) and boron, phosphorus-containing phenol formaldehyde resins (P-PFR and B, P-PFR), were synthesized using sol–gel and copolymerization techniques. These composite films were deposited via spin-coating onto an aluminum alloy (AA) for improve the corrosion protection. The effects of different types of PFR on the structural, thermal and mechanical properties and corrosion resistance of the composites were investigated. The structures and morphologies of the composites were investigated by the gel permeation chromatography (GPC), Fourier transform infrared (FTIR), scanning electronic microscopy (SEM) and atomic force microscopy (AFM). It was shown from the dynamic mechanical analysis (DMA) and thermal gravimetric analysis (TGA) that the mechanical and thermal properties of PU were improved by incorporation of PFR, P-PFR and B, P-PFR. In addition, the PU/PFR composites provided an excellent corrosion protection in comparison with PU according to potentio-dynamic and salt-spray analyses.

Utilizing synergetic effects of different fillers was an important strategy to develop high-performance polymer nanocomposites. In this work, novel hybrid nanofillers composed of graphene oxide (GO) and alkali lignin (L) were obtained successfully, and their reinforcing effect of phenol formaldehyde (PF) resin was fully investigated. The structures, morphologies, and properties of the GO-L nanocomposites were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscope, thermal gravimetry analysis, and Raman spectra. Dynamic mechanical analysis results showed that the GO-L–reinforced PF resin is much better than the single added GO and lignin with the same weight ratio. The effect of the filling ratio of GO-L on the storage modulus of PF was also investigated. Results showed that the storage modulus of PF was increased from 2015 MPa to 3675 MPa with the addition of 2 wt% of GO-L (3:7) hybrids.
