“…In contrast, PDMS 1 exhibited no change in the crosslinker peak due to the absence of iron particles in the system. The crosslinking process has been conducted previously at different temperatures, and the best crosslinking conditions for obtaining pristine PDMS are reported to be approximately 10 min of reaction at 150 °C, 45 min of reaction at 100 °C, or two days of reaction at room temperature [ 7 , 8 ]. Two mechanisms are available for stimulating the process of hydrosilation: the platinum-catalyzed mechanism and the radical chain addition mechanism [ 8 ].…”

“…These compounds evaporate at room temperature and pressure, causing the vapors to be present in both indoor and outdoor environments [ 3 , 4 , 5 ]. The hazards caused by the increasing amounts of petrochemical solvents, such as toluene, chloroform, pentane, petroleum ether, and n-butanol, should be particularly focused on, as these solvents are highly toxic and difficult to remove from the environment [ 6 , 7 ]. Compound adsorbents, which include shrink-bonded polymers and rubber materials, adsorb fluids on their solid structure and swelling.…”

“…The perfect PDMS system includes silanol-terminated PDMS, a crosslinker, and a catalyst as the major components, while reinforcing fillers and other additives may be added according to the application. Such systems combine the properties induced by the presence of metal with those specific to polymers, including the property of easy processability, which allows for the possibility of developing a wide range of composite materials with desired properties [ 7 , 8 , 9 ]. PDMS exhibits matchless behaviors in terms of elasticity, thermal stability, and mechanical, chemical, and optical properties [ 10 , 11 , 12 ].…”

“…Drainage of organic compounds to surface waters threatens the aquatic environment with effects such as acute and chronic toxicity in the aquatic organisms, accumulation of pollutants in the marine ecosystem, and loss of habitats and biodiversity of marine life [ 3 , 4 , 5 ]. Petroleum hydrocarbon compounds, including toluene, chloroform, pentane, petroleum ether, and n-butanol, are often drained into the surface and underground waters due to industrial activities, particularly the mishandling of petrochemicals, reservoir leakages, and inappropriate waste disposal practices [ 6 , 7 , 8 ]. Chemical contamination of water has caused water pollution to remain a serious environmental and public health problem.…”

“…PDMS-based hydrophobic sorbents were fabricated via bulk polymerization of tetraethyl orthosilicate and different lengths of PDMS, without using any activator, initiator, catalyst, or solvent. The prepared sorbents have a high swelling ability in organic liquids/oils in the range of 9–21 g/g [ 7 ]. Mazzotta et al proposed the production of reusable magnetic nanocomposites using PDMS/multiwalled carbon nanotubes and utilized them as absorbents to selectively collect oil from oily wastewater [ 11 ].…”

Volatile organic compounds pollute the environment and pose a serious threat to human health due to their toxicity, mutagenicity, and carcinogenicity. In this context, it is highly desirable to fabricate high-performance poly (dimethylsiloxane) (PDMS) composites to remove organic solvents from the environment using a simple technique. Therefore, in the present study, Fe-PDMS composites were fabricated using a technique based on magnetic induction heating with iron particles serving as a self-heating agent. Under an alternating magnetic field, the iron particles served as a thermal source that assisted in the progression of PDMS crosslinking. The influence of self-heating iron on the properties of the fabricated Fe-PDMS composites was also investigated. The hydrosilation reaction occurring during the crosslinking process was controlled using FT-IR. The heating efficiency of PDMS 1, PDMS 2, and PDMS 3 was studied as the function of induction time (0–5 min) and the function of iron content (0%, 1%, and 30% wt.%). The results revealed that the mechanical properties of the PDMS 2 composite were enhanced compared to those of the PDMS 1 and PDMS 3 composites. The mechanical properties of PDMS 3 were the least efficient due to cluster formation. PDMS 3 exhibited the highest thermal stability among all composites. Furthermore, the swelling behavior of different materials in various organic solvents was studied. PDMS was observed to swell to the greatest extent in chloroform, while swelling to a large extent was observed in toluene, pentane, and petroleum ether. PDMS swelling was the least in n-butanol. The elastomeric behavior of crosslinked PDMS, together with its magnetic character, produces stimuli-responsive magneto-rheological composites, which are quite efficient and suitable for applications involving the removal of organic solvents.

Organogels are an important class of gels, and are comparable to hydrogels owing to their properties as liquid-infused soft materials. Despite the extensive choice of liquid media and compatible networks that can provide a broader range of properties, relatively few studies are reported in this area. This review presents the applicability of organogels concerning their choice of components, unique properties, and applications. Their distinctive features compared to other gels are discussed, including multi-stimuli responses, affinity to a broad range of substances, thermal and environmental stability, electronic and ionic conductivity, and actuation. The active role of solvents is highlighted in the versatility of organogel properties. To differentiate between organogels and other gels, these are classified as gels filled with different organic liquids, including highly polar organic solvents and binary solvent systems. Most promising applications of organogels as sophisticated multifunctional materials are discussed in light of their unique features.

Multifunctional Oil‐Entangled Matrix Spray for Maritime Sustainability

Maritime transport, as the backbone of international trade, contributes to 3% of global greenhouse gas emissions. One major challenge to the sustainability of marine shipping is the fuel consumption associated with flow resistance to ship hulls. While passive approaches like superhydrophobic or lubricant‐infused surfaces hold promise for drag reduction, their scalability, stability, and durability are limited, particularly in oceanic scenarios. Here, an oil‐entangled matrix spray (OEMs) coating is developed to overcome the limitations of conventional surface modification. To create a drag‐reduction surface, liquid lubricant is rationally integrated with a polymer matrix, enabling the firm retention of the lubricant while maintaining high adhesion to various substrates. The resulting slippery interface achieves up to 48% drag reduction compared to an unmodified surface in a water tunnel test. Additionally, the hydrophobic, chemically inert, smooth, and slippery interface of OEMs enables multifunction of the coated substrates, including corrosion resistance to seawater and acid, reduced frosting accretion (by up to 68%), and low shear adhesion to ice (<11 kPa). Furthermore, the OEMs provides a universal platform to integrate customized functions such as photothermal effects, further enhancing interface performances by synergizing solar thermal energy and surface slipperiness. This study presents a promising surface modification strategy for improving the sustainability of marine vehicles where scalable, durable, and multifunctional surfaces are desired to achieve sustainable drag reduction under oceanic cruising and extreme weather conditions.
