This study measured the specific heat capacity of Phyllostachys edulis (Moso Bamboo) in three directions of the cylindrical coordinate system. The specific heat capacity measurement was conducted by the differential scanning calorimetry (DSC). Results from both internode and node parts of the bamboo culms were presented and compared in this study. Typical results at 25 °C were collected for an overall comparison of total specific heat capacity data. A major finding was that the specific heat capacity of the bamboo solid phase increased with the temperature. Relatively small pits, holes and tightly arranged cells resulted in a higher specific heat capacity. In the radial direction, results of both internode and node parts indicated that the specific heat capacity decreased from the external surface to the internal surface. In the tangential and longitudinal directions, average specific heat capacity values exhibited a non-uniform trend. No specific gradients were found in these two directions.
