“…As in polymer–polymer core shell particle formation, the interplay of thermodynamic and kinetic factors is also operating in clay encapsulation through (mini)emulsion polymerization. Looking from the starting point of miniemulsion polymerization, thermodynamically the clay has to be modified hydrophobically to make it miscible with the monomer initially . But the interfacial tensions change during the polymerization and the resulting morphology can still be armored latex particles.…”

Polymer encapsulation of clay platelets through (mini)emulsion polymerization can be a versatile method to obtain hybrid nanoparticles with several important applications. However, to achieve actual encapsulation of the single clay platelets inside latex particles is relatively difficult. For single clay platelet encapsulation, complete exfoliation and colloidal stability needs to be achieved as well as kinetic and/or thermodynamic control mechanisms to locate and maintain the position of the single clay platelet on the inside of the latex particle. An overview of these mechanisms will be given and an overview of the most relevant attempts in this area will be discussed in retrospect in the context of a systematic mechanistic understanding.

The oils leaked into water seriously threaten human health, thus it is urgent for scientific researchers to treat the pollution caused by oils. In this work, poly (styrene-co-butyl acrylate)-based fibrous membranes which were able to absorb and separate oils from water were prepared via electrospinning. Their thermal properties and crystallization behaviors were characterized by thermogravimetric analyzer, differential scanning calorimetry, and X-ray diffractometer. Field emission scanning electron microscopy was employed to observe their pores, and a gravimetric method was adopted to calculate their porosity. Water contact angle in air and oil contact angle in water were used to describe the hydrophobicity of the prepared fibrous membranes. Finally, the fibrous membranes were applied to the fields of oils absorption and separation. The results showed that the absorbencies of the fibrous membranes for unmoving pure oil were higher than 50 g/g, and the maximum absorbency even reached 91 g/g; additionally, the fibrous membranes also absorbed moving oil from the mixture of oil and water. The floating oil was completely separated from water by the used fibrous membrane after separation apparatus ran for 100 min.
