Bioinspired Strong Nanocellular Composite Prepared with Magnesium Phosphate Cement and Polyurea Aerogel
Materials Letters
Abstract
A strong nanocellular composite with stiff magnesium phosphate cement (MPC) particles and soft polyurea aerogel (PUA) has been synthesized and characterized. Utilizing the nano-confinement effect, the effective Young's modulus and the compressive strength of the ligaments are 8-10 times higher than those of PUA. Taking advantage of the hierarchical cellular structure of PUA, the low density (0.285 g·cm-3) and high porosity (86.4%) features are preserved. This bioinspired nano-composite design has shown superior composite action, offering both high strength and deformability. The verified analytical model reveals the bioinspired designing rules for MPC/PUA material system.
