Case Study

Linseed Oil Used for the Preparation of Anti-Bacterial Self-Healing Polymeric Coatings with CuO Nanoparticles

Karampoor, Mohammad Reza, Masoud Atapour, and Abbas Bahrami. Progress in Organic Coatings 184 (2023): 107879.

This study explores the utilization of linseed oil as a core material encapsulated within poly(urea-formaldehyde) microcapsules to develop advanced anti-bacterial self-healing polymeric coatings. The microcapsules, enhanced by copper oxide (CuO) nanoparticles, were synthesized via in situ polymerization in an aqueous medium under controlled acidic conditions (pH 3.0).
The synthesis procedure involved dispersing linseed oil and CuO nanoparticles (2-4 g/L, average size 70-80 nm) into a formaldehyde-urea-resorcinol solution, followed by stirring at 60 °C for 4 hours. Post-synthesis, the microcapsules were purified through xylene washing and freeze-dried. Incorporation of these microcapsules into an epoxy matrix was achieved at varying concentrations (5, 10, and 15 wt%), applied over a sandpaper-prepared steel substrate pre-coated with an epoxy primer.
Characterization via FESEM, XRD, and EDS confirmed the successful formation of uniform CuO nanoparticles and the integrity of the encapsulation process. The presence of linseed oil within the microcapsules endowed the coating with self-healing capabilities, while CuO nanoparticles provided antibacterial functionality.
This composite coating demonstrated enhanced durability and protection by autonomously repairing micro-cracks and inhibiting bacterial colonization, making it highly suitable for protective applications in corrosive or biofouling-prone environments. The study validates linseed oil's effectiveness as a natural healing agent in polymeric coatings designed for multifunctional surface protection.

Linseed Oil Used for the Synthesis of Waterborne Non-Isocyanate Polyurethane (NIPU) Coatings

Ling, Zichen, and Qixin Zhou. Green Chemistry 25.23 (2023): 10082-10090.

This study highlights the innovative use of linseed oil for the synthesis of environmentally friendly waterborne non-isocyanate polyurethane (NIPU) coatings, aligning with the principles of green chemistry. Linseed oil was first transformed into a cyclic carbonate derivative via a thiol-ene click reaction followed by direct esterification. The introduction of pendant cyclic carbonate groups significantly enhanced the curing rate and crosslinking potential of the NIPU network.
The synthesized linseed oil-based cyclic carbonate was reacted with a bio-based fatty acid diamine and an internal dispersion agent to prepare a series of waterborne NIPU resins. By adjusting the content of the dispersion agent and urethane segments, a range of NIPU formulations was developed. These coatings demonstrated excellent tunability in thermal stability, mechanical strength, and viscoelastic behavior.
Benchmarking against solvent-borne NIPUs and commercial isocyanate-based waterborne polyurethanes, the linseed oil-based NIPU coatings exhibited comparable or superior performance in adhesion, solvent resistance, hardness, and impact resistance. Importantly, the absence of isocyanates and use of bio-based materials position these coatings as safer, sustainable alternatives for industrial surface protection.
This work showcases linseed oil as a valuable renewable feedstock in the synthesis of high-performance, fast-curing, waterborne NIPU coatings, underscoring its potential in advancing eco-conscious coating technologies.

Linseed Oil Used for the Preparation of Antioxidant Nanoemulsions for Food Applications

Xie, Dongchao, et al. LWT 203 (2024): 116318.

This study presents the successful development of a linseed oil-epigallocatechin gallate nanoemulsion (LOE-NE), designed to enhance the nutritional value, stability, and functionality of high-oil food products. Prepared via ultrasonic emulsification, LOE-NE exhibited favorable physicochemical characteristics, including a narrow particle size distribution (160-180 nm), low polydispersity index (PDI < 0.2), and high colloidal stability (zeta potential ≈ -60 mV).
Formulation optimization revealed that an oil-to-water ratio of 1:9 combined with 1% EGCG content produced the most stable nanoemulsion. Interestingly, while oil-water ratio significantly influenced emulsion stability, EGCG content had negligible impact. Storage tests demonstrated that low-temperature conditions effectively suppressed EGCG degradation and browning, preserving its antioxidant efficacy.
Application trials further demonstrated the functional potential of LOE-NE in food systems. Incorporating 10% LOE-NE and 0.1% neohesperidin dihydrochalcone (NHDC) into salad dressing significantly improved sensory attributes while enhancing antibacterial and antioxidant activities. Additionally, the inclusion of LOE-NE in baked goods such as mooncakes reduced acrylamide formation and preserved unsaturated fatty acid content under high-temperature processing.
This work highlights linseed oil's value in forming nanoemulsion systems that improve bioactive delivery and food quality. The findings support the development of novel linseed oil-based functional food ingredients with potential to boost health benefits and extend product shelf life.
