“…PLA foam exhibited excellent reusability as the foam was able to capture 81% soybean oil and 88% kerosene oil even after 10 cycles of absorption–desorption. [ 10 ] This PLA‐based foam demonstrated excellent mechanical stability as it could withstand up to 185 kPa pressure. In one of the interesting studies, the PLA fabric was modified for the efficient treatment of oily wastewater.…”

During the transportation of oil, various oil‐spill incidents are reported. The utilization of oil sorbents for the treatment of oil spills is a promising approach among the all‐existing solutions. Nonbiodegradability and non‐renewability are the two major issues in the case of synthetic oil sorbents. In this review, the use of biodegradable polymers for oil‐spill cleanup is highlighted. In each section, the biodegradable materials and modifiers used, the method applied for a modification, the contact angle after modification, sorption capacities, and the reusability of developed biodegradable sorbents are extensively discussed. Mechanisms of biodegradation of biopolymers are also discussed. The manuscript also incorporates the recent developments in the fabrications of advanced sorbents with sustainable approaches along with challenges associated with current sorbents and future prospects.

“…These inorganic sorbents have limitations as they show low‐sorption capacity and poor hydrophobicity. [ 10 ] Among the natural organic materials straw, hull, sugarcane bagasse, and cotton fibers have been used. [ 11 ] The biggest problem associated with natural organic sorbents is poor selectivity and low‐sorption capacities.…”

“…Specifically, the hierarchically porous structure of sorbent can hold some these viscous oils which results in a high oil sorption capacity. [124][125][126][127][128][129][130][131][132][133] On the other hand, the absorption mechanism happens not only on the surfaces but mostly inside the polymer matrix with an extensive polymer matrix swelling (Figure 4B). The Flory−Rehner theory (Equation ( 1)) can be used to determine the network structure (i.e., crosslinking density and molecular weight between cross-links) and provide the structure−property relationships.…”

The conservation of ocean and freshwater have been crucial issues over the past decades, and oil/water separation is a well‐known technology to restore polluted water systems. In the meantime, oil sorbents serve as a promising means of achieving water conservation to recover from oil spills, which require a multi‐factorial approach to review high selectivity, capacity, and rate of oil recovery. However, reusability is a critical component to consider in incidents with large‐scale spills. With the development of sorbent technology, some studies have progressed to explore surface engineering and material design for high oil sorption capacity and durability. Thus, this systemic review, a summary of sorbent developments, serves as a guide to understanding practical applications that can apply to large‐scale oil spills and recognize remaining issues. In this review, the oil weathering process and oil sorption mechanisms in relation to the characteristics of target pollutants are introduced. Then, this comprehensive review focuses on materials in advanced sorbents. These materials have properties including, aligned channels for fast sorption, self‐heating capabilities for viscous oil cleanup, and magnetic‐responsiveness to enhance a collection of final products. The perspective and challenges for the next generation of oil spills remediation technology‐based oil sorbents materials are finally presented in the last section.

“…Recent reports have highlighted open-cell polymer foams as the preferred choice for oil absorbents, such as polyurethane sponges, − polylactic acid foams, , and polyolefin foams. − For instance, Wu et al successfully prepared superhydrophobic polyurethane sponges that exhibited a petrol absorbency of 13.26 g/g . Similarly, Wang et al prepared open-cell polylactic acid foam with an oil absorbency of 5 g/g .…”

This study aimed to prepare open-cell foams using a blend of long-chain branched polypropylene and polyolefin elastomer (LCBPP/POE) for the production of reusable oil absorbents. The supercritical CO 2 foaming process was conducted using a two-step batch rapid depressurization method. This unique two-step foaming approach significantly expanded the temperature and pressure windows, resulting in more uniform cells with smaller sizes, ultimately leading to higher expansion ratios and an increased open cell content. The foaming process was optimized by adjusting parameters, such as the LCBPP/POE ratio, foaming temperature, and foaming pressure, reaching a maximum open cell content of 97.6% and a maximum expansion ratio of 48. The influence of polypropylene (PP) crystallization was investigated with the aid of scanning electron microscopy and differential scanning calorimetry. Furthermore, the hydrophobic and lipophilic characteristics of the LCBPP/POE open-cell foam were determined via contact angle measurements and oil/water separation tests. Oil absorption tests revealed that the blended LCBPP/POE foam has a higher oil absorption capacity than that of the pure LCBPP foam. The cyclic oil absorption tests demonstrated the outstanding ductility and recoverability of the LCBPP/POE open-cell foam in comparison to those of the pure LCBPP foam. Over 10 cycles, the LCBPP/POE foam maintained a substantial adsorption capacity, retaining 99.3% of its initial oil absorption capacity. With its notable features, including a high open cell content, excellent hydrophobic and lipophilic characteristics, superior oil absorption capacity, impressive cyclic oil absorption performance, and robust reusability, LCBPP/POE open-cell foams exhibit significant promise as potential oil adsorbents for use in oil spill cleanup applications.
