The use of single-chain polymeric nanoparticles in cross-linked polymer matrices and investigation of their effects on thermal-mechanical and morphological properties

Although many types of nanoparticles are still the subject of research in polymer science, these nanoparticles are generally insoluble in solvents (TiO2, SiO2, calcite and its derivatives). Apart from these, fullerene (C60), polysilxoxyoxane (POSS) and cyclodextrins (particles in nanosize) are also used as nanoparticles soluble in polymer matrix or solvents. In recent years, the concept of polymer nanoparticles (nanoparticles) has emerged and opened a new door for the production of chemicals in nano-sizes. The concept of polymeric nanoparticles is based on folding within the polymer chains (intramolecular) by cross-linking with covalent or non-covalent bonds. Particles formed by folding polymeric chains by cross-linking methods are called "Single- Chain Polymeric Nanoparticle (SCNP)" in the literature. These structures, which can dissolve instead of dispersing in the solvent, exhibit homogeneous distribution in suitable polymer matrices, allowing the production of composite materials with higher properties. Within the scope of this thesis, cross- linked polymer matrix composite materials containing 0.5-3.0% by weight of nanoparticles will be preparedand compared with thermosets without nanoparticles, the thermal, mechanical and morphological properties of polymer materials will be examined.
