The science that studies the exchanges between chemical and electrical energy is called electrochemistry. Electrochemical processes are either spontaneous chemical reactions that produce electricity or processes in which an electric current causes a chemical reaction. Reactions that occur during electrochemical processes are redox reactions in which reduction and oxidation occur. Corrosion, which is an undesirable and destructive reaction, can be given as an example to understand the mentioned terms. Corrosion, which has different effects on metal, polymer and ceramic materials, is represented by dissolution or film formation in metals, degradation in polymers, while ceramic materials are resistant to these changes [1] . Indeed, corrosion is an electrochemical process and it can be explained by the movement of electrons in a reaction. This science can also be called the science that studies the phenomena that occur in oxidation-reduction reactions, in which the exchange of electr...
Shape memory materials, which can be called adapting to environmental conditions, are mainly obtained in alloys, ceramics and polymers. This adaptation is the state of changing some properties of the material against external factors such as heat, light, electrical field and pH, and regaining its former properties when these factors are removed. In other words, the material has a permanent shape at room temperature. It deforms at a high transition temperature and retains its shape after cooling. It returns to its original shape upon reheating. The low density, easy fabrication and easily adaptable glass transition temperature of shape memory polymers (SMPs) compared to shape memory alloys and shape memory ceramics are outstanding factors. Mostly amorphous polymers, semicrystalline polymers and liquid crystalline elastomers have this shape memory effect. Figure 1 Scheme of shape memory cycle [1] . Shape memory cycle (Fig. ...
