“…Firstly, the straw was pretreated with acid, and the acid cellulose and lignin formed by cellulose and lignin on the surface of the rice straws reacted with acid, which made the cellulose and lignin have strong electron withdrawing properties and produce unstable cations on the surface of the fiber [30,31]. There are a few hydrophobic and lipophilic adsorbents [9][10][11][12][13][14], including magnetic particles [15][16][17], textile [18][19][20][21], and modified commercial sponges [22][23][24], which have been applied for oil adsorption. At present, materials with high oil absorption are generally industrially synthesized as high oil-absorbing resin materials [25].…”

Frequent oil spills have caused serious consequences to the ecosystem and environment. Therefore, in order to reduce and eliminate the impact of oil spills on biology and the environment, oil spill remediation materials must be considered. As a kind of cheap and biodegradable natural organic cellulose oil-absorbing material, straw has an important practical significance in the treatment of oil spills. In order to improve the ability of rice straw to absorb crude oil, rice straw was first treated with acid and was then modified with sodium dodecyl sulfate (SDS) through a simple charge effect. Finally, the performance of oil absorption was tested and evaluated. The results illustrate that the oil absorption performance was greatly improved under the conditions of 10% H2SO4, for a 90 min reaction at 90 °C, under 2% SDS, and reacted for 120 min at 20 °C, and the rate of adsorption for rice straw to crude oil was raised by 3.33 g/g (0.83 to 4.16). Then, the rice stalks before and after the modification were characterized. Contact angle analysis shows that the modified rice stalks display better hydrophobic–lipophilic properties than unmodified rice stalks. The rice straw was characterized by XRD and TGA, and the surface structure of the rice straw was characterized by FTIR and SEM, which explain the mechanism of surface-modified rice straws with SDS to improve their oil absorption capacity.

“…The harm of water-based emulsion to the environment is far less than that of oil-based. With the enhancement of people’s environmental awareness, the development and utilization of waterborne fluoropolymer emulsion has attracted more and more attention [ 28 , 29 , 30 ]. Fluoropolymer emulsion with water basis has great advantages.…”

Fluoropolymer: A Review on Its Emulsion Preparation and Wettability to Solid-Liquid Interface

et al. 2023

In the preparation of a superamphiphobic surface, the most basic method is to reduce the surface free energy of the interface. The C—F bond has a very low surface free energy, which can significantly change the wettability of the solid–liquid interface and make it a hydrophobic or oleophobic, or even superamphiphobic surface. Based on the analysis of a large number of research articles, the preparation and application progress in fluoropolymer emulsion were summarized. After that, some corresponding thoughts were put forward combined with our professional characteristics. According to recent research, the status of the fluoropolymer emulsion preparation system was analyzed. In addition, all related aspects of fluoropolymer emulsion were systematically classified in varying degrees. Furthermore, the interaction between fluoropolymer structure and properties, especially the interaction with nanomaterials, was also explored. The aim of this review is to try to attract more scholars’ attention to fluorocarbon interfacial materials. It is expected that it will make a certain theoretical and practical significance in the preparation and application of fluoropolymer.

“…Polymer materials can be used as wetting reversal agents to solve these problems. 12 Fluoropolymers have very low surface free energy due to the small atomic radius of fluorine atoms and the large bond energy of the C−F bond in the structure. 13,14 Therefore, fluoropolymers are widely used in the preparation of interface materials with antiadhesion, antifriction, oil−water−gas separation, and etc.…”

Reservoir wettability is an important factor in the process of reservoir reconstruction. Especially in hydrophilic formation, it is easy to cause a water-locked phenomenon. A new type of fluoropolymer microemulsion was prepared by emulsion polymerization, and its structure and properties were characterized. The average particle size in the prepared emulsion was about 2.0 μm. The emulsion had good stability and wettability reversal performance for the storage of 30 days. After the treatment of 2.0 wt % emulsion, the contact angle between the core and water changed from 26 to 128°, the core surface free energy decreased from 66 to 2.6 mN/m, and the saturated water imbibition amount of the core decreased from 1.38 to 0.15 g. The ability of the fluoropolymer microemulsion to enhance oil recovery was evaluated by the visual displacement experiment. The fluoropolymer microemulsion can increase the displacement efficiency by more than 10%. The wettability of the core changed from hydrophilicity to hydrophobicity, and wettability reversal was achieved.
