Materials for coatings

This course is part of the programme:
Materials (Third Level)

Objectives and competences

The primary goal of this course is to give students the knowledge of modern coatings from self-assembeled monolayers, over sol-gel coatings, to thicker anticorrosion coatings for marine environment. Students get to know foundations of raw coating materials i.e. binders, pigments, fillers, solvents and interactions among them, which are finished after curing. In greater detail they realize terms i.e. surface free energy, hydrophobicity and oleophobicity, self-cleaning. Extensively they become familiar with the coatings for energy harvesting.

Students gain necessary competences to prepare competitive scientific project to obtain coatings for off shore objects, to prepare and perform experiments with corrosion stability in lab, and to quantitatively analyse measurements and interpret the results.

Intended learning outcomes

Knowledge and understanding:

The students learn about the principles of various modern surface modification techniques. They also learn about methods for preparing surfaces to increase wetting and adhesion. They learn about the basic components of coatings, their interactions and their purpose in coatings. They learn to use different binders for different environments and learn to distinguish between solvent based coatings and water-based coatings. They get acquainted with sol-gel coatings that allow the preparation of inorganic coatings. They learn the basic principles for the preparation of self-sealing monopoles and their use. They learn about essential analytical methods for the characterization of coatings from self-assembled monolayers to thick anti-corrosion coatings to protect offshore objects. They learn to choose which combination of electrochemical methods is optimal for analysing the protection effectiveness against corrosion of the coatings and properties of materials associated with them. They acquire the knowledge necessary for independent performance of measurements at measuring stations in various electrochemical laboratories and skills in writing proposals for designing and testing coatings.

Assessment

During the course students prepare individual projects on coatings and on quantitative electrochemical analysis on real data from research practice. At the end of the course they prepare a final project on selected topic. All projects are prepared in a written form and defended orally in an open discussion with professor and students. 50/50%

Lecturer's references

Doc. dr. Ivan Jerman (h index = 18) He received Ph.D. degree at the University of Ljubljana, Faculty of Chemistry and Chemical Technology in 2009. Currently he is a head of Coating development laboratory, part of Department of Materials Chemistry, at National Institute of Chemistry. He participated in several EU projects: APOLON B, INNOSHADE, MULTIFUNCOAT, BONACO, NECSO, NANORESTART, Wabaselcoat, national project and projects with the industry. His main research filed is connected with coatings for renewable energy harvesting, especially solar energy. He is using different molecules for modification of pigments, metallic surfaces, textiles as a tool for preparation of surfaces with high solar absorptance, low thermal emittance, electrical conductivity, water and oil repellence and self-cleaning property and synthesis of flame retardant additives for polymeric materials.

He published over 100 publications including over 45 refereed scientific papers in the international journals with impact factor. He is co-author of 7 patents (two of them sold to industry).

For inventions, research achievements and the use of scientific research in implementing innovation in economic practice he received in 2010 prestigious Puh Distinction.

Since 2011, he has been lecturing at the Faculty of Technologies and Systems Novo mesto (Chemical technology), Slovenia, and was promoted the second time to assistant professor in 2017.
