Abstract:

Poly(lauryl methacrylate)s with anthracene moieties in the side chain were converted with C60-fullerene and phenyl-C61-butyric acid methyl ester (PCBM), resulting in new remendable (self-healing) polymeric materials. The utilization of differentlysubstituted anthracene monomers enabled the tuning of the reactivit y and the resulting mechanical properties. Copolymers with dif-ferent contents of the anthracene moieties were synthesized and characterized using size exclusion chromatography,1H nuclear mag-netic resonance (NMR) spectroscopy as well as differential scanning calorimetry (DSC).1H NMR spectroscopic studies were utilizedin order to investigate the reversibility of the Diels–Alder reaction between copolymers with C60-fullerene and PCBM, respectively, insolution. In order to investigate the conversion of the polymers with C60-fullerene and PCBM in bulk, additionally, DSC, nanoinden-tation, rheology, atomic force microscopy (AFM), 3D microscopy, simultaneous thermal analysis (STA) and FT-Raman investigationswere performed. The fullerene-containing copolymers could be healed in a temperature range of 40–80 8C. Consequently, a new gen-eration of low temperature remendable polymers could be established.
