PRODUCT INTRODUCTION
description
N-Methylaniline (NMA) was used in the preparation of self-assembled poly(N-methylaniline)-lignosulfonate (PNMA-LS) composite spheres with reactive silver-ion adsorbability. NMA was also used in electrodeposition of poly(N-methylaniline) (PNMA) coatings on a steel disc electrode using potentiodynamic, potentiostatic and galvanostatic techniques.
