Fin dalle prime pubblicazioni in merito, datate inizio anni '90, i Nanotubi di Carbonio (CNTs) sono al centro delle attenzioni di molti ricercatori, date le loro straordinarie proprietà meccaniche ed elettriche, infatti pesando solo un sesto dell'acciaio sono quasi cento volte più resistenti a trazione. Le applicazioni studiate finora sono tra le più disparate, partendo dalla nano-elettronica fino ad arrivare a numerose addizioni degli stessi in composti polimerici. Questo campo di ricerca, mosso anche da evidendi esigenze di mercato, sta prendendo largamente piede in edilizia, dove la possibilità di avere materiali con prestazioni sempre più elevate, diminuendo ingombri, consumi e costi, più che uno sfizio per pochi è diventata una vera e propria necessità.

Le Nanofìbre di Carbonio (CNFs), altra forma allotropica del Carbonio, vengono anch'esse in contro alle esigenze dei laboratori di ricerca di tutto il mondo, infatti con proprietà qualitativamente analoghe ai CNTs ma prestazioni e costi decisamente ridotti, possono essere sostituite a questi ultimi nelle prime fasi di studio.
