“…Interestingly, other class of carbon nanomaterials like Buckminster fullerene C 60, well explored in the field of solar cell research [31,32], is rarely explored in fuel cell arena and can also be a potential additive for composite membrane electrolytes in fuel cells due to its high electron affinity, high volumetric functional group density and its radical scavenging property [33]. To understand these properties in detail, very few research reports are found with PEMs comprising fullerene for fuel cell applications.…”

“…These data give indirect evidence that the clusters are destructed at high velocity gradients. The inclusion of fullerenes, other carbon and metal oxide nanoparticles in different polymers modifies the properties of films and membranes based on these polymers [3,9,[19][20][21][22][23][24][25][26][27][28][29][30]. For example, the addition of small amounts of fullerene (up to 2-10 wt%) to poly (phenylene oxide) (PPO), PS, and PA changes selectivity and permeability of membranes made from these polymers in gas separation and pervaporation processes [3,[28][29][30].…”

Abstract. Poly(phenylene isophtalamide) (PA) was modified by fullerene C 60 using solid-phase method. Novel ultrafiltration membranes based on nanocomposites containing up to 10 wt% of fullerene and carbon black were prepared. Properties of PA/C 60 composites in solutions were studied by light scattering and rheological methods. The relationship between characteristics of casting solutions and properties of nanocomposite membranes was studied. Scanning electron microscopy was used for structural characterization of the membranes. It was found that increase in fullerene content in nanocomposite enhances the membrane rigidity. All nanocomposite membranes were tested in dynamic (ultrafiltration) and static sorption experiments using a solution of protein mixture, with the purpose of studying protein sorption. The membranes modified by fullerene demonstrate the best values of flux reduced recovery after contact with protein solution. It was found that addition of fullerene C 60 to the polymer improves technological parameters of the obtained composite membranes.

“…Moreover, ODCB and DMAc are completely miscible with one another and have close boiling point. 13 Hengbin Wang et al investigated new fullerene derivatives, tri-cyanohydrofullerene, HC 60 (CN) 3 , and poly{4-[2-[2-(2-methoxyethoxy)ethoxy]ethoxy]benzyl} fullerene, C 60 (TEO) n , have been synthesized as additives for proton conducting membranes. C 60 (TEO) n has also been found to be very effective in improving the dispersion of HC 60 (CN) 3 in the Nafion ® matrix.…”

Ionic polymer-metal composite (IPMC) actuators employing sulfonated poly(styrene-b-ethylene-co-butylene-b-styrene) (SSEBS) ionomer and fullerene-C60 composite membrane were developed. Due to the poor electroactive performance of IPMC actuators employing pure SSEBS, fullerenes as the reinforcement agent are incorporated. The bending responses under both direct current (DC) and alternating current (AC) excitations were investigated. Compared with the actuator based on pure SSEBS, the tip displacement of IPMC actuator based on Fullerene-SSEBS composites has great improvement under DC excitations, and also the responses are quick and harmonic under AC excitations. More meaningful improvement is that Fullerene-SSEBS based IPMC actuators don't have back relaxation towards the cathode under DC activation for a long time. SEM study was carried out on the samples of Fullerene-SSEBS actuators. Platinum layers were finely synthesized on the interfaces of Fullerene-SSEBS actuators. Present results show that the fullerene, C60, can be successfully applied to reinforce the electro-mechanical properties of the ionic polymer metal composite actuators.
