assembly immobilization, which generally involves self-organizing
the functionalized CNTs with other components by different driving
forces. For example, the interaction between positively charged
poly(diallyl dimethyl ammonium) chloride (PDDA) and negatively
charged oxidized CNTs was used to fabricate multilayer films for
the determination of dimethyl ammonium [19], while the π–π in-
teractions between CNTs and PDDA may be also responsible for the
assembly, as results demonstrated by Yang et al. [20]. Additionall
