Abstract

To give the PMMA polymer self-repairing properties microspheres (MK) were added into the polymer solution at three different concentrations (1, 3, 5% Wt.). Formaldehyd resin-walled MKs are manufactured with Glycidyl Methacrylate (GMA), which is used as self-healing agent. For ease of production, 1% wt. were added to PMMA solution for produce PMMA / MK / nanoclay nanocomposites. In order to improve the mechanical properties of the PMMA / MK composite, two different clay nanoparticles, nanotubes and nanoplates, were reinforced into the PMMA / MK structure. Production of live PMMA / MK / HNTs and PMMA / MK / MMT nanocomposites was achieved by Atom Transfer Radical Polymerization (ATRP) method. In order to investigate the changes in mechanical properties reinforcement were made at three different concentrations. PMMA / MK structure was reinforced by 1, 3, 5% Wt. Halloysite clay nanotubes (HNTs) and montmorillonite clay nanoplates (MMT). In the nanoclay-reinforced PMMA / MK nanocomposite, after the mechanical damage caused by external environmental factors, the polymer nanocomposite was tried to be restored to the original state by self-healing. Nanocomposite specimens were produced in accordance with the geometry required by the Shore D hardness test, the notched Izod impact test, the 3-point bending test and the compression test standards. Changes in mechanical properties of PMMA / MK / HNTS and PMMA / MK / MMT nanocomposite samples were compared with changes in mechanical properties of PMMA polymer. The change in flexural strength of nanocomposite specimens was investigated after self-healing from mechanical damage.
