Relações de escala para o problema de confinamento de macromoléculas

Abstract

ln this work we studied the confinement of polimeric structures restrict in a region limited by two plane surfaces, proposing a model to simulate this problem in a computer. Hence we suppose that the statistical approach to the problem is based in a computer simulation of these macromolecules by a kind of self-avoiding walk(SA W), called indefinitely growing sel-avoiding walk(IGSA W). Tlie results from the computer simulation of the confinement of polimeric c4ains between two plane surfaces considering like a indefinitely growing SA W show us that ~ the fractal dimension from the scaling law between the density-density correlation function c(r) and the distance end-to-end f and from the scaling law between the distance end-toend r and the number of monomers N are in a good agreement with the literature. Furtermore we establish a scaling law relationship between the separation h of the two plates and the number of monomers N for the problem of the polymer brigdging between two plane surfaces, our results give evidence of that they are better than the numeric results obtained by Hong Ji et al.
