Abstract: The dynamic mechanical behavior and the tensile properties of pseudo-semi-interpenetrating polymer networks (pseudo-SIPNs) based on double-C60-end-capped poly(ethylene oxide) (FPEOF) and poly(methyl methacrylate) (PMMA) were studied. For pseudo-SIPNs involving FPEOF with a longer PEO chain length, the storage modulus can reach 42 GPa at 40 °C, representing an astonishing 16 times increase over PMMA. There is an optimum FPEOF content to achieve maximum enhancement in the storage modulus. With increasing FPEOF content in the network, the plasticizing effect of PEO chains begins to offset the reinforcing effect of C60. The Young's moduli of the pseudo-SIPNs are about twice than that of PMMA, whereas the tensile strengths, the ultimate strains, and toughness are lower than those of PMMA. The mechanical properties of the pseudo-SIPNs are as good as those of PMMA/carbon nanotube composites.
