Embodiment Construction

[0067] Experimental part

[0068] sample preparation

[0069] It is determined to use samples of carbon steel and stainless steel (AISI304 and AISI316). The coating is applied to a test sheet or sample measuring 2 cm x 1 cm. Some test samples were prepared in a suitable manner by an initial wash with water and acetone to remove coarser impurities on the samples before applying the coating, after which they were prepared by immersing them in CH 2 Cl 2 Medium for 1 min (while stirring with a magnetic stirrer) to bring the sample surface as close to perfect as possible.

[0070] This is done to increase the efficiency of the cleaning sample method by providing turbulent flow near the sample surface.

[0071] Coatings were also applied to unwashed samples in order to reproduce the industrial process as closely as possible. It has been found that there is no significant difference between the contact angles after coating and heating the samples, thus demonstrating that the ste...

Abstract

The present invention relates to the use of perfluorinated compounds as a surface coating to counteract the formation of fouling. The present invention also relates to a method for producing a surface coating capable of preventing the formation of fouling, this method comprising the application of a polar solution of a perfluorinated compound followed by a heat cycle conducted at controlled temperatures.

Description

technical field [0001] The present invention relates to the use of perfluorinated compounds as surface coatings for preventing fouling. [0002] The invention also relates to a method for preparing a surface coating capable of inhibiting fouling formation, which method comprises the application of a polar solvent of a perfluorinated compound followed by thermal cycling at a controlled temperature. Background technique [0003] The properties of materials in the various fields of their application often depend on surface and interface conditions. Properties such as wettability and coefficient of friction are closely related to the salient features of any given substrate, which also illustrate that the first atomic layers of the interface are quite different than expected in their composition and structure based on mass composition, but It is these properties that determine the surface properties of a given material. Therefore, various attempts have been made to control and ...
