Abstract

The morphology, shock absorption and dynamic mechanical properties of a new architectured multifunctional materials- polyaspartic esters (PAE) based ployureas were investigated through FTIR, atomic force microscope(AFM), drop-weight test and dynamic mechanical analysis(DMA). The PAE based polyureas were prepared from synthesized PAE and hexamethylene diisocyanate（HDI）trimer /polytetramethylene ether glycol (PTMG) prepolymer. The FTIR results indicated that hydrogen-bonded urea carbonyl of PAE based polyurea was 76.1%, and the length of hydrogen bonding was 0.306nm. The microphase separation phenomenon of the PAE based polyureas were observed directly through AFM topography studies. PAE based polyureas exhibited unique shock absorption and dynamic mechanical properties.
