“…Porogen agent was contained in the polymeric network during the polymerization process. Then it can be removed in the post‐processing by ethanol extraction, which will result in pores . The Aerosil R812 can weaken the entanglement and cross‐linking of polymer chains, which may lead to the macropore (the diameter of pore in PSB is around 5 to 15 µm).…”

“…It is evident that the oil absorbencies of PSB‐SiO 2 increase with time until reaching a platform. The oil absorption saturation times of PSB‐SiO 2 toward chloroform, toluene, gasoline, and diesel are 30, 45, 45, and 150 min, respectively, which are significantly superior to those of PSB (the oil absorption saturation times of PSB toward chloroform, toluene, gasoline, and diesel are 60, 90, 120, and 180 min, respectively) . This fast oil absorption speed attribute to the loose structure of PSB‐SiO 2 .…”

A novel composite oil‐absorbent microsphere poly(stearyl methacrylate‐co‐butyl acrylate) (PSB)‐SiO2 was prepared by introducing hydrophobic nano‐silica Aerosil R812 into the suspension polymerization system of stearyl methacrylate and butyl acrylate and was characterized by Fourier transform infrared and scanning electron microscopy energy‐dispersive spectrometer. PSB‐SiO2 has a loose network structure and exhibits remarkably fast oil absorption speed in relatively high saturated oil absorbency. Besides, PSB‐SiO2 has good oil retention and reusability. Moreover, the saturated oil absorbencies of PSB‐SiO2 toward toluene, gasoline, and diesel over water are roughly equivalent to that in pure oil. Owing to its excellent oil absorption performances, PSB‐SiO2 will find applications in removing oil spills and organic pollutants over water. Copyright © 2016 John Wiley & Sons, Ltd.

“…The pseudo‐second order model is presented in Equation as follows:

\frac{t}{Q_{t}} = \frac{1}{k_{2} {Q_{e 2}}^{2}} + \frac{t}{Q_{e 2}}

where k 2 is the rate constant of the pseudo‐second order sorption kinetics, and Q e2 and Q t are the sorption capacities at equilibrium and at time t, respectively. Equation was used to fit the experimental sorption data in Figure A to show whether the sorption of the PP/POE foams for cyclohexane follows the pseudo‐second order kinetics model.…”

The objective of the present work was to study the sorption kinetics of open‐cell polypropylene/polyolefin elastomer (PP/POE) blend foams. First, open‐cell PP/POE foams of different cell structures were prepared by controlling the foaming temperature via a continuous extrusion foaming process. Second, the effect of the cell structures on the sorption process, rate, and capacity was studied. Pseudo‐first order and pseudo‐second order models were applied to study the sorption kinetics of the PP/POE foams for cyclohexane. Third, the sorption rate and sorption capacity by both volume and weight of the PP/POE foam for different oils and solvents were studied to show how the intrinsic properties of the testing oils and solvents affected the sorption performance. The results showed that the sorption with the PP/POE foams followed the pseudo‐second order kinetics model. Both the cell structures of the foams and the intrinsic properties of the testing oils and solvents affected the sorption performance. For the same testing oil, a higher open‐cell content in the foam was favorable for a higher sorption rate, and a higher void fraction was favorable for a higher sorption capacity. For the same foam, a lower viscosity of the testing oil was favorable for a higher sorption rate. The sorption capacity by volume was closely related to the viscosity of the testing oil, while both the viscosity and the density of the testing oil determined the sorption capacity by weight.

In this work, a hybrid nanocomposite of poly(styrene-co-butyl acrylate-cododecyl acrylate) and octavinyl polyhedral oligomeric silsesquioxane (ovi-POSS) was synthesized by suspension polymerization and the composite resin was characterized by Fourier transform infrared, scanning electron microscopy energy-dispersive spectrometer and thermal gravimetric analysis. The effects of ovi-POSS content on the oil absorbency of hybrid composite resin were investigated. The results indicated that the maximum saturated oil absorption rate of sample PSBLA/ovi-POSS-1 with 1 wt% ovi-POSS content toward four oils and organic solvents (toluene, xylene, gasoline, and diesel) are, respectively, 20.51, 18.56, 12.48, and 7.03 g g À1 , and the process taken just about 5 min. The absorption kinetic model fitting proved that the adsorption behavior of the four oils on PSBLA/ovi-POSS-1 resin microspheres was dominated by the physical adsorption. Besides, PSBLA/ovi-POSS-1 has good oil retention rate (stay over 95% after centrifuging at 3000 rpm for 5 min) and reusability (for 12 times). These excellent oil absorption performances are attributed to the loose network structure of the composite resin. The rapid and efficient oils absorption properties give the composite resin potential practical applications in many areas.
