“…Different types of inorganic and organic particles were already used in heterophase polymerizations, e.g., silica, zinc oxide, clay, or magnetic particles as well as polymer latex particles [6][7][8][9][10]. Moreover, the stability of the polymerization system and the appearance of the resulting polymerization products are strongly influenced by the choice of suitable co-monomers, co-solvents, initiators, and other reaction parameters such as reaction conditions and pH or salt content [5,11,12].…”

Nanofibrillated cellulose (NFC) was used as biobased stabilizing agent in the heterophase polymerization of methyl methacrylate (MMA) to nanoscale poly(methyl methacrylate) (PMMA) spheres. NFC/MMA suspensions at different NFC/MMA ratios were prepared in water, and the suspension stability was evaluated before the subsequent polymerization. The resulting polymerization products as well as products from several control experiments were analyzed via optical microscopy, SEM, and isolation experiments associated with thermogravimetric analysis. PMMA spheres had diameters in the range of 150-250 nm and were regularly distributed within the NFC network, whereas NFC acted as a stabilizer during the polymerization. The appearance of the resulting PMMA spheres within the NFC network was influenced by different factors, such as the reaction conditions, the initiator, and the solubility of the monomer.

“…The microspheres are between 0.5~2.0 µm in diameter and the surfaces of them are rough. These observations suggest that the Pickering emulsion polymerization using AIBN as the initiator mainly obeys the monomer droplet nucleation mechanism [33,34]. Figure 6 shows the suggested formation mechanism of composite microspheres I.…”

We report the preparation, mechanisms and thermal properties of core-shell structured polymer/inorganic nanoparticle composite microspheres prepared by Pickering emulsion polymerization. Stable Pickering emulsion was firstly fabricated by using surface-modified nano-SiO2 particles as stabilizer. And then, two kinds of polystyrene/nano-SiO2 (PS/SiO2) composite microspheres with different sizes and morphologies were synthesized using hydrophobic azobisisobutyronitrile (AIBN) and hydrophilic ammonium persulfate (APS) as initiator, respectively. The possible mechanisms of Pickering emulsion polymerization initiated by different initiators were proposed according to the results of transmission electron microscope (TEM) and scanning electron microscope (SEM). The chemical structure and molecular weight of the composite microspheres were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffractometer (XRD) and gel permeation chromatography coupled with a multi-angle laser light scattering photometer (GPC-MALLS). Thermogravimetric analysis (TGA) and differential scanning calorimeter (DSC) were used to comparatively analyze the thermal properties of nanocomposites and corresponding pure polymer. The results indicated that the decomposition temperature and glass transition temperature (Tg) of nanocomposites were elevated to a certain degree due to the existence of nano-SiO2

Polyaniline (PANI)/zinc oxide (ZnO) nanocomposite was synthesized by in-situ polymerization. X-ray diffraction patterns, UV-visible spectroscopy, SEM, and TEM were used to characterize the composition and structure of the nanocomposite. Nanostructured PANI/ZnO composite was used as photocatalyst in the photodegradation of methylene blue dye molecules in aqueous solution. The photocatalytic activity of PANI/ZnO nanocomposite under UV and visible light irradiation was evaluated and was compared with that of ZnO nanoparticles. ZnO/ PANI core-shell nanocomposite had greater photocatalytic activity than ZnO nanoparticles and pristine PANI under visible light irradiation. According to these results, application of PANI as a shell on the surface of ZnO nanoparticles causes the enhanced photocatalytic activity of the PANI/ZnO nanocomposite. Also UVvisible spectroscopy studies showed that the absorption peak for PANI/ZnO nanocomposite has a red shift toward visible wavelengths compared with the ZnO nanoparticles and pristine PANI. The effect of different operating conditions on the photocatalytic performance of PANI/ZnO nanocomposite in the photodegradation of methylene blue dye molecules was investigated in a bath experimental setup.
