Bamboo scrimbers were made of bamboo bundles treated with different thermal temperatures. The effects of the thermal temperature on color, water resistance, mechanical properties, surface free energy and thermodynamic performance of the scrimber samples were investigated. The results showed that with increased treatment temperature, color of the bamboo scrimbers became darker with improved water-resistant properties, increased surface free energy, decreased mechanical properties and decreased storage modulus. It was suggested that suitable thermal treatment temperature for bamboo bundles in production should be selected according to application requirements of bamboo scrimber products.
