###### Abstract
The most common type of suspension technique is powder polymerization, in which the polymer is insoluble in its monomer and consequently precipitates out, producing uneven grains or particles. PVC is an excellent example of powder suspension polymerization. Bead suspension is the second form of this kind of polymerization, in which the polymer is soluble in its monomer, creating smooth spherical particles. To impart a charge to the toner particle, a charge control agent (CCA) is introduced to the toner [10]. CCAs are frequently ion surfactants or metal soaps that produce inverse micelles in the liquid dispersant [11]. Toner materials or particles can be charged positively or negatively depending on the particle materials and CCA employed [12]. [PERSON] [13] defines CCAs as compounds that aid the management of the electrostatic charge applied during the printing process. Ionic materials (either anionic or cationic) can be colored or uncolored. The CCA imparts a positive charge to the toner particles [14; 15]. Quaternary ammonium and diazo-type compounds can be used as CCAs [16]. However, some charge control additives are incompatible with thermoplastic toner resins, or they adversely affect the electrical properties of the polishes. In addition, CCAs with low molecular weight may leach out some toner composition and contaminate the carrier's surface. Improved toner composition uses partially quaternized vinyl pyridine polymer as the CCA [17; 18; 19]. According to [PERSON] et al. [20], there are charge additives, charge aides, and charge-directing agents in addition to CCAs. Moreover, there is a class of compounds that can stabilize the triboelectric charge in matrix systems, such as electrophotographic toners [21], and these substances are known as charge stabilizers. Charge stabilizers have lower charging magnitudes but more robust long-term charge stability than CCAs. A charge stabilizer can be used within a matrix system or as an external blended addition [22]. [PERSON] et al. [23] report the effect of an externally added CCA on the contact charge between polymers, namely, low-density polyethylene (LDPE) and high-density polyethylene (HDPE), with a diameter of around 5 mm, concluding that the CCA makes LDPE charge positively and HDPE charge negatively. [PERSON] et al. [24] describe the preparation of poly(styrene-co-butyl acrylate)-encapsulated single-walled carbon nanotubes (SWCNTs) under ultrasonic irradiation. First, they chemically modified the SWCNTs by grafting 3-(trimethoxy)-propyl methacrylate-silane (silane-coupling agent, KH750) onto the surface of the SWCNTs. In the second step, they initiated in situ emulsion polymerization of monomer styrene (St) n-butyl acrylate (nBA) in the presence of KH570-g-SWCNTs using ultrasonography. As a result, a poly (St-nBA)/SWCNT emulsion was created. The transmission electron microscopy (TEM) micrographs in that study, however, indicated that the SWCNTs had been coated with the produced polymer. The objective of the present paper is to use CNTs as a pigment instead of carbon black (CB) for toner applications. To achieve this goal, suspension polymerization was selected as the best way to produce latex of micron size that is well suited to encapsulate CNTs. The main challenges to reaching our objective are the dispersion of CNTs, the insertion of the CCAs in the polymerized latex, and the reduction in the retarding/inhibiting effects of mainly carbonyl groups when CB is used.
