This paper was to investigate basic properties of micro/ nano fibrils from poplar with a high pressure homogenizer. Their basic properties were tested by laser particle size analyzer, scanning electron microscopy (SEM) and X-ray diffractometer (XRD). The test results showed that if the fiber slurry moved from 20 to 40 circulations through the homogenizer, for 10% of the micro/nano fibrils, the particle size was reduced from 1.2 μm to 160 nm and its surface area per unit volume was increased from 1.63 × 104 to 8.38 × 104 cm2/cm3 when the concentration of fiber in suspension was 0.5% and the homogenization pressure was 800 bar. A distribution in the dimensions of the cellulose whiskers was seen by scanning electron microscopy. It was proved by X-ray diffractometer that the crystal degree of the micro/nano fibrils had a small change during the conversion process.
