    Research Project
    Design, Synthesis and Investigation of New Nano-Dimensional Compounds
    Chemical Engineering
    Combination of conjugated polymers and Polyhedral oligomeric silsesquioxane (POSS) units under the same roof was taken place recently. In very few numbers of studies in the literature, it was reported that POSS units gave thermal, mechanical, optical and electrochemical stability to the condujugated polymers. In this study, in order to overcome the problems faced by the industrial field of conjugated polymers (insolubility, thermal, mechanical, optical and electrochemical instability, etc.) the inorganic (POSS) and organic (thiophene) units will be melted in the same pot for producing new POSS based polymeric materials. While the most important reason for using POSS as inorganic segment in the hybrid compound that will be synthesized is not only being nanosized but also the ability to give thermal and electrochemical stability and make the polymer soluble, 3,4-ethylenedioxythiophene and 3,4-propylenedioxythiophene, which are easily and linearly polymerized and provide to obtain electroactive polymers, will be used as organic segments. In the first stage of the project, our aim is primarily to sythesize and analyze the compounds whose structures were designed and specified and the sythetic pathways were determined. In the next step, necessary conditions to obtain electroactive polymers (homopolymer and copolymer) will be determined by investigating the electochemical and optical properties of compunds. With the realization of the project, it will be a milestone progress towards polymerization and applications (hydrophobic surfaces, electrochromic devices and polymeric light emitting diodes) of these compounds. The results of the study have the ability to be “know-how” and “patent”. Also, these results will be a data source for the future projects that can be pursued with “public” and “private” sectors. Besides, the subject of the project will be a part of a doctoral thesis, with the originality of the scope of the project and the outcomes have potential to contribute the researcher identity of Atilim University. Besides there is possibility for outcomes to become a patent, they have strong possibility to be published in prestigious journals and presented in conferences.

    Self-Cleaning Surfaces: A New Approach for Water-Repellent Surfaces
    Chemical Engineering
    It was observed that natural structures (such as lotus and rice leaves) which exhibit superhydrophobic (water-hating) and self-cleaning properties have micro- and nanoscale roughness on their surfaces. Typical superhydrophobic surface protects the surface from getting wet by repelling water drops. Owing to water repellency property, self-cleaning superhydrophobic surfaces have several applications in industry and daily life. In this study, the aim is to prepare superhydrophobic materials containing nano- and microscale surface roughness by using sol-gel and hydrothermal methods and to coat onto different surfaces (glass, paper,textile, metal etc.) In the study, in order to obtain nano- and microscale surface roughness, coating material will be prepared by using polymer, silica nanoparticles and metal complexes. Implementation of the prepared material onto the surface will be done via spray coating, spin-coating, and/or sol-dip-coating techniques. Hydrophobic and self-cleaning properties of the prepared material will be examined via contact angle and surface free energy measurements and the required optimizations will be done. Surface morphology, physical and chemical properties of the obtained surfaces will be characterized via SEM, TEM, UV-Vis and FTIR analysis. For the purpose of determining strength of material, some physical tests (film thickness, spreading and appearance, adhesion, strength, scratch resistance, brightness, adequacy of contamination, ultraviolet and temperature strength resistance) and chemical tests (detergent resistance and detergent /alkali) will be done. In the project, it is suggested that depending on coating type, surface can achieve properties such as antibacterial, anti-mold, antifungal, protection against acid, water and stain repellency, low contact adhesion, and preliminary studies for future are considered to be carried on in the biochemistry laboratory of our department. In the near future, when we consider the coating of surfaces exposing external factor that has mentioned above with this technology, the preparation of such a material at Atılım University and therewithal the production through industry partnership and introducing for usage while considering commercially carry great importance.
