Randomly charged polymers in porous environment

    Research output: Contribution to journalArticlepeer-review


    We study the conformational properties of charged polymers in a solvent in the presence of structural obstacles correlated according to a power law ~ x-a. We work within the continuous representation of a model of linear chain considered as a random sequence of charges qi = ±q0. Such a model captures the properties of polyampholytes - heteropolymers comprising both positively and negatively charged monomers. We apply the direct polymer renormalization scheme and analyze the scaling behavior of charged polymers up to the first order of an ?= 6-d, ?= 4-a-expansion.
