Printed electronics are emerging technology products that we use in every moment of our daily lives. It is used in many fields from health, textile, electronics to communication. Inks with nanometal or organic content can be used in printed electronics. The ability of printed electronics to withstand temperature makes its use widespread in the electronics industry. Main aim of the study is to combine surface modified graphene oxide-based conductive inks with flame retardant materials. In this study, an effective and simple approach for the preparation of polyurethane acrylate (PUA) screen printing ink containing surface modified reduced graphene oxide (rGO) which has flame retardant activity. A new and effective flame-retardant additive; 9,10-dihydro-9,10-oxa-10-phosphaphenanthrene-10-oxide (DOPO), silane coupling agent and reduced graphene oxide was synthesized. In this synthesis, first reduced graphene oxide was modified with (methacryloyloxy)propyltrimethoxysilane, and then reacted with DOPO to obtain a flame-retardant monomer containing P and Si. Based on the successful modification reactions, screen-printing ink containing polyurethane acrylate and different amounts of modified graphene oxide content (0, 5 and 10 wt%) were prepared and screen printed on the paper surface. In addition, coatings were made on the paper surface to determine some the properties. LOI values, thermal properties, contact angle values, conductivity and surface properties of the obtained prints and coatings films were investigated. As a result, conductive screen-printing ink resistant to high temperatures was successfully produced and printed coatings and free films were formed.

Numerical calculation of homogenized properties of piezoelectric composites Kurt, Mustafa; Gürses, Ercan; Department of Aerospace Engineering (2022-11-25) Piezoelectric materials are the materials we use in many parts of our lives without being aware. These materials can convert electrical energy into mechanical energy or vice versa. Although this ability renders piezoelectric ceramics very attractive materials for sensing and actuation applications, their use often remains limited, due to their weight and brittleness. As a result of these drawbacks, piezoelectric composites are developed, and they offer superior performance compared to monolithic piezoelectr...
Processing and characterization of textured barium ferrite ceramics Aydoğan, Eda; Dericioğlu, Arcan Fehmi; Timuçin, Muharrem; Department of Metallurgical and Materials Engineering (2012) Technological advances results in the fact that quite a large number of electronic equipment interacts with its environment leading to the malfunction of the devices. This brings about the necessity of using proper electromagnetic (EM) wave absorbers/shields to avoid such interactions. In order to absorb EM waves in a large frequency band from several MHz to GHz, barium hexaferrite (BaHF) ceramics which are produced as textured ceramics as well as in multilayered form can be used. Textured ceramics are proc...
Analysis of the combined effect of bad posture and vibration on helicopter pilots Sezgin, Önder Cem; Birlik, Gülin; Department of Engineering Sciences (2002) One of the most important physical effects of the technological innovations, which we happily welcome, in our daily lives, is to be exposed to vibration. Vibration and bad posture affect, seriously various parts of the human body, especially the spine of the persons. In this thesis, emphasis is given to the effects of bad posture and vibration on musculo-skeletal system. In order to reach to the subjective assessments of the vibration exposed and vibration non-exposed groups of people, questionnaires were p...
Modeling effects of material properties and composition on ultrasound propagation Özkök, Okan; Uludağ, Yusuf; Department of Chemical Engineering (2017) Ultrasonic methods for material characterization have increasingly been used for the last decades thanks to advances in electronics and digital technologies since conventional methods accommodate several disadvantages like being time consuming. Advanced technology has brought highly accurate measurements with reasonable confidence level, and flexible ultrasonic testing parameters. The aim of this work is to carry out material characterization by combining modeling study and outputs of the ultrasonic device....
Synthesis of Graphene-MoS2 composite based anode from oxides and their electrochemical behavior Sarwar, Saira; Karamat, Shumaila; Saleem Bhatti, Arshad; Aydınol, Mehmet Kadri; Oral, Ahmet; Hassan, Muhammad Umair (2021-10-16) High energy storage capacity and longer life span make rechargeable Li-ion batteries the first choice in portable electronics. Here, a graphene-MoS2 composite material is investigated as a potential electrode material which enhances the electrochemical storage ability of the Li-ion batteries (LIBs). Graphene-MoS2 composite is synthesized from graphene oxide (GO), molybdenum trioxide and thiourea via hydrothermal route. Formation of graphene-MoS2 composite (molar ratio 1:2) is confirmed by X-ray diffraction ...
