Abstract

We report experimental studies of the statics and dynamics of diffusion-limited polymerization. The fractals obtained were produced electrochemically from neutral precursors, and have a Hausdorff dimension of 1.74±0.03. The width of the active growth zone increases at the same rate as the fractal radius. The chemical dimensionality determined by scale-dependent conductivity measurement is 0.96±0.04. This implies a value for the spectral dimensionality of 1.26±0.04. © 1986 The American Physical Society.
