Nature had developed efficient mechanisms for enduring high-energy impacts and interactions, which we are currently studying in order to develop new energy-dispersive composites for eventual development into personal protective systems. The three methods of current interest are: (i) sacrificial bonds and hidden lengths, (ii) graded structures, and (iii) order at several length scales. To study these, our focus is on metal ion and histidine based complexations, creating polymeric density and strength based gradients, and creating a mesostructure inside a compressible lattice.
