Abstract  

We study the large-time behavior of the charged-polymer Hamiltonian H n of Kantor and Kardar [Bernoulli case] and Derrida, Griffiths, and Higgs [Gaussian case], using strong approximations to Brownian motion. Our results imply, among other things, that in one dimension the process {H [nt]}0≤t≤1 behaves like a Brownian motion, time-changed by the intersection local-time process of an independent Brownian motion. Chung-type LILs are also discussed.

active for the prolonged period [ 8 – 11 ]. The technique further makes it possible to investigate the effect of physical aging (annealing) of the charged polymer on the charge storage, its distribution and transport in the material [ 12 – 15

capillary and a high voltage power source is connected to produce an electric field [ 1 , 4 ]. A jet is ejected from the surface of a charged polymer solution when the applied electric field strength overcomes the surface tension. The ejected jet extends in

Introduction The idea of using an electric field to spin fibers from a charged polymer melt or solution was conceived in the 1930s. Electrospinning, as the process was called, was a straightforward method to produce nanofibers

biocompatibility. These properties make it able to interact with negatively charged polymers, macromolecules and also with certain polyanions in aqueous solution [ 1 – 3 ]. This interaction usually occurs under relatively easy conditions and low cost, when compared

bridge interactions are responsible for polymer adsorption. Otherwise the adsorption of negatively charged polymer chains on the negatively charged solid surface should not occur. As can be seen in Table 1 , hydrogen bonds can be formed between
