ELECTRICAL-CONDUCTIVITY OF POLY(ACRYLIC ACID) - POLYACRYLAMIDE COMPLEXES

The conduction mechanism in the interpolymer complex resulting from th e interaction between poly(acrylic acid) (PAA) and polyacrylamide (PAA m) was investigated. The characteristic features of the relation betwe en the logarithm of conductivity, log sigma, and 1/T are different fro m those corresponding to the individual components of the complex. The value of a for the complex was found to be less than its correspondin g values for PAA or PAAm. The effects of the weight fraction of each p olymer and the ionic strength of the solutions on the conductivity of the complex were also studied. The data showed that the a of the compl ex depends on the weight fraction of the polymers. (C) 1998 John Wiley & Sons, Inc.
