Abstract: The invention provides polymeric reagents of a formula: Xa—Y-Zb wherein X is a latent reactive group, Y is a polymeric backbone, and Z is a melamine group. In some aspects of the above formula, a is in the range of 0.5 to 90 mole percent, and b is in the range of 10 to 99.5 mole percent. The latent reactive group can be a photoreactive group or a thermally-reactive group. Monomeric units for preparing the polymeric reagents are also described. Methods of using the polymeric reagents to provide modified surfaces are also described, as well as methods of providing biocidal surfaces and methods of treating habitats for halogen-sensitive microorganisms.

Abstract: Disclosed are transition metal electrodes for electrochemical cells using gel-state and solid-state polymers. The electrodes are suitable for use in primary and secondary cells. The electrodes (either negative electrode or positive electrode) are characterized by uniform dispersion of the transition metal at the nanoscale in the polymer. The transition metal moiety is structurally amorphous, so no capacity fade should occur due to lattice expansion/contraction mechanisms. The small grain size, amorphous structure and homogeneous distribution provide improved charge/discharge cycling performance, and a higher initial discharge rate capability. The cells can be cycled at high current densities, limited only by the electrolyte conductivity. A method of making the electrodes (positive and negative), and their usage in electrochemical cells are disclosed.
