“…[34] In contrast to the number of studies on bulk materials and thin films from the direct utilization of elemental sulfur, high sulfur content polymer colloids constitute a largely unexplored area with only a few methods available for their preparation. [35,36] Polymer colloids in aqueous systems offer the advantage of environmentally friendly materials and can be exploited in a range of applications that cannot directly be accessed using bulk materials. [37] Recently, polymerization of aqueous polysulfides, formed from the dissolution of elemental sulfur in aqueous sodium sulfide, with various bi-and trifunctional comonomers has been demonstrated to yield aqueous dispersions of high sulfur-content polymers.…”

High sulfur content polymeric materials, known for their intriguing properties such as high refractive indices and high electrochemical capacities, have garnered significant interest in recent years for their applications in optics, antifouling surfaces, triboelectrics, and electrochemistry. Despite the high interest, most high sulfur‐content polymers reported to date are either bulk materials or thin films, and there is a general lack of research into sulfur‐rich polymer colloids. Water‐dispersed, sulfur‐rich particles are anticipated to broaden the range of applications for sulfur‐containing materials. In this study, we present the preparation and size control parameters of an aqueous dispersion of sulfur‐rich polymers with the sulfur content of dispersed particles exceeding 75 wt.%. Employing polymeric stabilizers with varying hydrophilic‐lipophilic balance (HLB), along with changing the rank of inorganic polysulfides, allowed for the control of particle size in the range of 360 nm to 1.8 µm. The sulfur‐rich colloid demonstrated antioxidant properties in water, demonstrating the potential for the use of sulfur‐rich polymeric materials readily removable, heterogeneous radical scavengers.This article is protected by copyright.

“…8 However, traditional miniemulsions are kinetically stabilized by specific surfactants and cosurfactants, which are required to provide the electrostatic/steric stabilization against the collision/coalescence between the small droplets. 6,9 Also, the surface energy (Gibbs free energy) of the smaller droplets invariably surpasses the larger one, leading to the thermodynamically-driven spontaneous diffusion of the molecules from the small droplets to the larger droplets through the continuous phase. 10 As a result, the stability of the miniemulsion is severely affected by the diffusional degradation (Ostwald ripening), where the small droplets are sacrificed to the growth of the large one.…”

Advancements in the synthesis of sulfur‐rich materials are driving progress across diverse fields owing to the rich and tunable functionalities of those materials. These materials are typically valued for their electrochemical behaviors, high refractive indices, heavy metal affinity, and ability to form dynamic covalent bonding. As a result, their applications span various industries including electronics, catalysis, lithium‐sulfur batteries, water reclamation, and optoelectronics. Moreover, elemental sulfur, a byproduct of the petroleum industry, is produced abundantly, necessitating the exploration of novel valorization routes for polymers made from this feedstock. The unique combination of properties of sulfur‐rich polymers also makes them an ideal platform for the development of high‐performance functional coatings, offering durability and tailored functionalities for protective coatings, thus enhancing materials lifespan and performances in a variety of environmental conditions. The presence of dynamic covalent bonds in many sulfur‐rich polymers enables the creation of self‐healing coatings, while sulfur itself or the comonomers can contribute to antimicrobial, antifouling, and corrosion‐resistant properties. Furthermore, sulfur‐rich polymers have the potential to be used in the design of icephobic and superhydrophobic coatings. This underscores the versatility of sulfur‐rich polymers as a platform for the creation of advanced coatings with superior properties.
