“…Therefore, although the process is conveyed by the combination of physical and chemical phenomena, the good fitting of the transient absorption capacity by the PSOM suggests that chemisorption mechanism plays a predominant role in the absorption of the contaminating oils in the bentonite‐silicone composite foams. Subsequently, the absorption rate decreases cause of the progressive decrease of free active sites on the porous foam surface 47 . During this stage, the oil uptake slightly increases due to a limited diffusion of the pollutant toward not embedded foam pores 48 …”

“…Subsequently, the absorption rate decreases cause of the progressive decrease of free active sites on the porous foam surface. 47 During this stage, the oil uptake slightly increases due to a limited diffusion of the pollutant toward not embedded foam pores. 48 The oil absorption is also influenced by the microand macro-structure of the foam, making the design of an optimal foaming ratio is an essential condition for its effective use for oil spill recovery.…”

The aim of this article is the synthesis and characterization of bentonite‐filled siloxane foams for oil spills recovery. Composite foams at varying filler content in the range 35–45 wt% were investigated. The sorption kinetics and capacity of composite foams in different oils (e.g., kerosene, virgin naphtha, pump oil) were assessed. As a reference, water absorption capacity was also evaluated. Among all, the composite foam filled with 40 wt% bentonite (B‐40 batch) shows the lowest affinity with water and good absorption capacity with oils (mainly light oils) reaching an absorption capacity at saturation equal to 10.3 and 518.2 wt% in water and virgin naphtha, respectively. Furthermore, isothermal absorption curves were analyzed using three kinetic models: pseudo‐first order, pseudo‐second order, and Elovich models. The equilibrium isotherm fitting results were optimal using the pseudo‐second order model, indicating that chemisorption phenomena play a key role in the speed of the absorption phase for these PDMS‐based composite foams. Finally, a correlation was addressed between morphology, foam microstructure, absorption capacity, and kinetics.

Sorption kinetics of pollutant oils, such as kerosene, virgin naphtha, crude oil, and pump oil, into porous siloxanic foams filled with carbon nanotubes (CNTs) are investigated. Both, pristine and functionalized, CNTs are used as foam fillers. Among all, the foam filled with pristine CNT shows a poor affinity with water and high sorption rate in light oils, in which it achieves the highest absorption values (7991 mg g−1 after 660 s and 6685 mg g−1 after 420 s, respectively, in virgin naphtha and kerosene). The kinetic data are described by the pseudo‐first order, pseudo‐second order, Elovich and intraparticle diffusion models. Results show that chemisorption processes are rate limiting the sorption step. In fact, pseudo‐second order model better represents the equilibrium isotherm data. © 2018 Wiley Periodicals, Inc. J.

Wood is a renewable material that has been widely utilized as indoor and outdoor construction and decoration material in our daily life. Although wood has many advantages (i.e., light weight, high strength, low price and easy machinability), it has some drawbacks that influence dimensional stability, cracking and decay resistance in real practical applications. To mitigate these issues, superhydrophobic surfaces have been introduced to wood substrates, creating superhydrophobic wood surfaces (SHWSs) that can improve stability, water resistance, ultraviolet radiation resistance and flame retardancy. Herein, the recent developments and future perspectives of SHWSs are reviewed. Firstly, the preparation methods of SHWSs are summarized and discussed in terms of immersion, spray-coating, hydrothermal synthesis, dip-coating, deposition, sol-gel process and other methods, respectively. Due to the characteristics of the above preparation methods and the special properties of wood substrates, multiple methods are suggested to be combined to prepare SHWSs rather than each individual method. Secondly, the versatile practical applications of SHWSs are introduced, including anti-fungi/anti-bacteria, oil/water separation, fire-resistance, anti-ultraviolet irradiation, electromagnetic interference shielding, photocatalytic performance, and anti-icing. When discussing these practical applications, the advantages of SHWSs and the reason why SHWSs can be used in such applications are also mentioned. Finally, we provide with perspectives and outlooks for the future developments and applications of SHWSs, expecting to extend the utilization of SHWSs in our daily life and industry.
