'Waterproofing' Project for Money and Valuable Papers from SU Chemical Engineering Department faculty member

Assistant Professor, Department of Chemical Engineering, Selcuk University in KONYA. Assoc. Dr. Mustafa Karaman has successfully completed the 'waterproofing' project with nano technology. Assist. Assoc. Dr. Karaman said, "With this project, it is possible to add a protective feature especially to valuable papers such as money, bills and bonds, manuscripts with historical features or international agreements."

Noting that the lotus plant, which grows in muddy and dirty environments, inspired him in realizing this project, Assist. Assoc. Dr. Mustafa Karaman said:
“The lotus plant grows in muddy and dirty environments. Despite this, the leaves of the plant are always clean. Because when the smallest speck of dust comes on the plant, it immediately shakes its leaves and pushes the dust granules towards certain points. We have succeeded in applying this repulsion feature of the flower on napkins and fabrics with the chemical vapor deposition method.”


Assist. Assoc. Dr. Mustafa Karaman stated that they successfully completed the 'Super water-repellent surface synthesis by chemical vapor deposition method' project in Selcuk University Advanced Technology Research and Application Center in 2010 with the support of TUBITAK. Stating that the surface shapes of the object to which the vapor deposition method was applied did not deteriorate, Assist. Assoc. Dr. Karaman said, “After the application we carry out with the steam deposition method, wetting, adhesion and dirt retention are prevented without deforming the shapes of the surfaces. Our coatings take place at the nanometer scale. We apply nano technology. Therefore, it does not change the geometric shape and physical properties of the surface. Super water repellent surfaces are formed. Our aim is to ensure that the work we carry out in the laboratory environment can also be industrially produced. We are currently working on this issue," he said.


Pointing out that it is possible to cover all kinds of surfaces with the application they have developed, Assist. Assoc. Dr. Karaman said, “One of today's most important technological developments is flexible displays and solar panels. Their application areas are gradually expanding. Both in daily life, in the aviation industry, and in the space industry, these appear as the materials of the future. Extending the life of these materials also passes through such coatings. With our technique, we can make delicate, delicate and paper-like sensitive surfaces waterproof with an innovative technology and cover them without compromising their originality.”


Stating that the biggest problem of the industry is chemical solvents and the damage they cause to the environment, Assist. Assoc. Dr. Karaman said:

“The biggest feature of this project is that we perform our functional surface coatings at very low costs without using any solvents. Solvents are the industry's biggest problem. Especially in the textile and paint industry, such solvents cause environmental problems. Both the cost of purchasing these solvents and the costs they bring to the industry and industrialists to dispose of them are recorded in the expense section. But in our practice this disappears.”


In the experiment he carried out in the laboratory, Assist. Assoc. Dr. Karaman said, “With this project, it is possible to add a protective feature to increase the life of especially valuable money, bills, bonds, manuscripts with historical features or international agreements.”
