Abstract: 4-(ω-(methylimidazole) hexyloxy)-4 ′-(cyano)-biphenyl (CbP) was synthesized using 1,6-dibromohexane, cyanobiphenol and N-methyl imidazole as main materials. The wood pulp cellulose solution was prepared by adding CbP to ionic liquid 1-allyl-3-methylimidazolium chloride（AMIM•Cl） as a cellulose solvent, and then its rheological property was tested by Haake rheometer. Wood pulp cellulose liquid crystal films (WPC/CbP) were prepared from the solution by dipping precipitation phase transformation. Fourier infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) were used to characterize the structure of the film and differential scanning calorimetry (DSC) was used to characterize the thermal stability of the film. The strength of the film was tested by electronic universal tensile testing machine, and the UV resistance of the film was tested by UV-visible near-infrared spectrometer. Results showed that the viscosity of WPC/CbP increased with the increase of the mass fraction of CbP, and the lowest value appeared when the mass fraction of CbP was 3%, in which a liquid crystal phenomenon was observed by polarizing microscope (POM). Compared with WPC film, the thermal stability and tensile strength of the WPC/CbP were improved because of the intramolecular and intermolecular hydrogen bonds of cellulose and CbP. The tensile strength and flexibility of the WPC/CbP were improved by 27.56% and 46.52%, respectively. However, the UV transmittance of the WPC/CbP was reduced by about 35%, indicating its potential application in the field of high strength packaging.
