“…On the other hand, the presence of lamellar Ti 3 C 2 T x and SiO 2 further protects the polymer matrix from severe wear and tear. Moreover, the interface of composites also promotes stress transfer from the PI matrix to the Ti 3 C 2 T x @SiO 2 , which avoids stress concentration 28–30 …”

Polyimide (PI) is a special engineering plastic, widely involved in mechanical components, instruments, and petrochemicals. However, single PI material is inevitably subject to wear and tear in practice, which leads to weakened material properties. In this work, Ti3C2Tx@SiO2 was prepared to enhance the wear resistance and lubrication properties of PI by intercalating SiO2 into the interlayer of Ti3C2Tx sheets. Ti3C2Tx@SiO2/PI composites were fabricated in two steps to test the tribological performances. SiO2 particles change the form of interfacial friction from sliding to rolling, thus relieving direct friction between material and steel ball. So, the composites have a minimum COF (COF = 0.33) when the content of Ti3C2Tx@SiO2 is 0.80 wt%. Moreover, the average value of wear rate was 0.24 × 10−5 mm3/(N·m) when Ti3C2Tx@SiO2 content was 1.60 wt%, which was 91.0% lower compared to the PI matrix. During the friction process, the abrasive chips of the material migrate to the surface of the steel ball to form a transfer film, which protects the material and thus reduces the wear rate. Therefore, the hybrids Ti3C2Tx@SiO2 are effective and important wear‐resistant agents and solid lubricants to improve the wear resistance and lubricity of PI or other polymer materials.Highlights SiO2 insert Ti3C2Tx is a key factor in changing sliding friction into rolling friction, effectively reducing the COF. The average wear rate was 91.0% lower than that of the polyimide matrix when Ti3C2Tx@SiO2 content was 1.60 wt%. The minimum COF of Ti3C2Tx@SiO2/PI composites reached 0.33 when the content of Ti3C2Tx@SiO2 was 0.80 wt%. The transfer film effectively reduces further wear of the material during friction.

“…Chen et al 21 performed adsorption experiments with high‐performance resins, and the saturated adsorption of kerosene could reach 11.58 g g −1 . Chen et al 22 used suspension polymerization to prepare a resin with an adsorption capacity of up to 11.14 g g −1 for gasoline, which has excellent oil–water separation properties. Wu et al 18 used 4‐tert‐butylstyrene, divinylbenzene and ethylene/propylene/diene as the polymerization monomers, toluene as solvent, and prepared a porous oil‐absorbing resin by suspension polymerization, which showed the maximum removal efficiency of styrene was 99.47% under static sorption process.…”

To improve the adsorption and reusability of polypropylene (PP) fiber membranes, the organically modified saponite (Sap@P(St‐co‐MMA)) was prepared by solution polymerization. Furthermore, PP‐based nanocomposite fiber membranes with strong oil adsorption, thermal stability, and reusability were prepared via melt‐blown technology. The increased specific surface area of PP‐based nanocomposite fiber membranes (PP‐1.5%) provided more active sites for the oil adsorption. Simultaneous rheology and Fourier transform infrared measurements tests showed that Sap@P(St‐co‐MMA) enhanced the crystallinity of PP matrix, promoted the regular arrangement of molecules, and improved the intermolecular interaction force, which was beneficial for the oil adsorption. The adsorption of PP‐1.5% (1.5 wt% addition of Sap@P(St‐co‐MMA)) fiber membrane for xylene and kerosene reached a maximum of 15.84 and 22.84 g g−1, respectively. In the treatment of coal tar wastewater, the removal rate of oil can reach 62.9%, and the removal rate can still reach 51.17% after five cycles of experiments. In summary, PP‐1.5% fiber membrane does not produce secondary pollution to the environment, and is a kind of oil removal material with good application prospect.Highlights PP‐based nanocomposites fiber membrane with strong oil adsorption was prepared. Organically modified saponite had strong heterogenous nucleation for PP matrix. Sap@P(St‐co‐MMA) increased the specific surface area of PP‐based fiber membrane.

“…Coating is a novel packaging technique, in which natural edible macromolecules (e.g., polysaccharides, proteins, etc.) are used as the raw materials and cured on the food surface by impregnation, spraying, or coating to form a tightly structured, protective, and semi-permeable coated film (in this review, the term coating only referred to coated film, while the term film referred to both individual film and coated film) [5]. Coating can give continuous protection to foods when there is no outer packaging or the outer packaging is broken.…”

Foods are susceptible to deterioration and sour due to external environmental influences during production and storage. Coating can form a layer of physical barrier on the surface of foods to achieve the purpose of food preservation. Because of its good barrier properties and biocompatibility, prolamin-based film has been valued as a new green and environment-friendly material in the application of food preservation. Single prolamin-based film has weaknesses of poor toughness and stability, and it is necessary to select appropriate modification methods to improve the performance of film according to the application requirements. The practical application effect of film is not only affected by the raw materials and the properties of the film itself, but also affected by the selection of preparation methods and processing techniques of film-forming liquid. In this review, the properties and selection of prolamins, the forming mechanisms and processes of prolamin-based coatings, the coating techniques, and the modifications of prolamin-based coatings were systematically introduced from the perspective of food coating applications. Moreover, the defects and deficiencies in the research and development of prolamin-based coatings were also reviewed in order to provide a reference for the follow-up research on the application of prolamin-based coatings in food preservation.
