A coating composition for application to a subsea component or structure includes a cellulose acetate, a plasticizer, a vegetable oil, and an ethylene-based polymer stabilizer that are mixed together. The plasticizer is epoxidized linseed oil. The vegetable oil is selected from the group including vegetable oil and soybean oil. The ethylene-based polymer stabilizer has a pigment carried therein. The ethylene-based polymer stabilizer is low-density polyethylene. The pigment is titanium dioxide and carbon black.

Fractal-like polymeric particles having a hierarchical, branched structure are disclosed. The particles have fibers with nanometer-scale diameters on their peripheries, which enables a number of unique and highly desirable properties. The particles are fabricated by a method combining phase separation and shear forces of different solutions, in particular a polymer solution. In addition, the particles may be used as coatings, nonwovens, textiles and viscosity modifiers and adhesives, among other applications.

A method is used to prepare silver nanoparticles or copper nanoparticles in the form of a silver nanoparticle cellulosic polymeric composite or a copper nanoparticle cellulose polymeric composite, respectively. A cellulosic polymer, organic solvent having a boiling point at atmospheric pressure of 100 C. to 500 C. and a Hansen parameter (.sub.T.sup.Polymer) equal to or greater than that of the cellulosic polymer, ascorbic acid, and a nitrogenous base are mixed to form a premix solution. At room temperature or upon heating the premix solution to a temperature of at least 40 C., a solution of reducible silver ions or reducible copper ions is added. The resulting silver or copper nanoparticle composite is cooled, isolated, and re-dispersed in an organic solvent, providing a non-aqueous silver-containing or copper-containing dispersion that can be disposed on a substrate to form an article.
