Polymeric nanocomposites containing non-covalently bonded fullerene C60: properties and applications

Abstract

The results of studying the wide range of properties of polymeric nanocomposites containing small doses of non-covalently bonded fullerene C 60 which are of interest for modern technologies are presented. The character of bonds between components of the composites and the possible reasons for improvement of the properties of the nanocomposites in comparison with pure polymers are considered.

Ранее в работах [15][16][17][18][19] исследовалось влияние фуллеренa С 60 на физико-механические параметры полимерной матрицы и проде-монстрирована возможность достижения эффекта упроч-нения. Тем не менее, модифицированные фуллеренoм пленки, приготовленные нами на первом этапе иссле-дования, не показали преимущества по прочностным параметрам в сопоставлении с исходными пленками.…”

Fullerene derivatives as nano-additives in polymer composites

“…Tasaki et al 180 modified the Nafion 1 117 membranes with fullerene C 60 and fullerenol C 60 (OH) 12 . The modified membranes had higher proton conductivities and held more water than the parent Nafion membranes, especially at low RH < 50%.…”

“…Postnov et al 181 prepared Nafion ± fullerenol (C 60 (OH) n (n = 22 ± 24), C 70 (OH) 12 ) and Nafion ± trismalonate C 60 [C(COOH 2 ) 3 ] composite films and studied their proton conductivity at different RH levels. The composite containing 1.7 mass % of tris-malonate demonstrated the maximum proton conductivity at low RH, viz., nearly 6.3610 75 S cm 71 at RH = 32%, which was about 30 times higher than that of pure Nafion.…”

“…4 ± 11 Incorporating fullerenes into polymer matrices has been shown to improve the physical and transport properties of the host polymers. 12,13 Fullerenes are typically produced by arc or combustion methods and subsequent purification of reaction products. The resulting fullerenes can then be mixed with polymers.…”

Self-Cleaning Photocatalytic Polyurethane Coatings Containing Modified C60 Fullerene Additives

“…Covalent incorporation of C 60 fullerene into polymers offers controlled distribution and reduced leaching, albeit often at the sacrifice of photoactivity [32,33]. In contrast, non-covalent incorporation of C 60 fullerene offers simplified formulation and unaffected photophysical properties [34]. Furthermore, non-covalent incorporation of an amphiphilic fullerene species affords the potential for surface segregating photoactive additives.…”
