Polyaniline dispersions: preparation of spherical particles and their light-scattering characterization

On the origin of colloidal particles in the dispersion polymerization of aniline

“…Poly[(vinyl alcohol)-co-(vinyl acetate)] was found to be a good steric stabilizer [53,54], while the completely hydrolyzed analogue, poly(vinyl alcohol), was less efficient and even failed in some cases to stabilize PANI colloids [33]. In the present study, the presence of poly(vinyl alcohol) in the reaction mixture has led to the shortening of the induction period (Fig.…”

Thermoresponsive polyaniline nanoparticles: Preparation, characterization, and their potential application in waterborne anticorrosion coatings

“…Since the processing of PANIs using these organic solvents leads to serious environmental pollution and potential damage to human health, ecofriendly processing of waterborne PANIs has attracted great interest in both academic and industrial research [5]. Waterborne PANI nanoparticles (PANI-NPs) are the simplest among many nanostructures of PANIs [6], which can be prepared from various approaches including self-doping [11,12], counterion induced method [13,14], and dispersing polymerization with specific stabilizers, such as poly(vinyl alcohol) (PVA) [15,16], polyacrylamide [17], poly(vinyl pyrrolidone) [18,19], hydroxypropylcellulose [20], chitosan [21,22], poly(N-isopropylacrylamide) [22], or sophisticated tailor-made copolymers [23][24][25][26][27]. Although so many kinds of PANI-NPs have been reported, research on smart waterborne PANINPs is still scarce [22,27,28].…”

Synthesis and electrical characteristics of polyaniline nanoparticles and their polymeric composite

“…Polymeric stabilizer absorbed onto the PANI nuclei prevents the PANI particles from aggregation via steric stabilization [9]. Recently, several kinds of polymeric stabilizers were reported including poly(vinyl alcohol), poly(N-vinyl pyrrolidone), poly(vinyl methyl ether), and methyl cellulose [10][11][12].…”
