Samenvatting

Koolstofnanobuizen hebben erg goede elektrische, mechanische en thermische eigenschappen. Als we de koolstofnanobuizen oplosbaar maken in organische oplosmiddelen, kunnen we deze nanobuisinkten gebruiken om elektronische apparaten te produceren, zoals zonnecellen en veldeffecttransistoren. Het maken van inkten van koolstofbuizen heeft ertoe geleid apparaten te kunnen vervaardigen op dezelfde manier als het drukken van kranten.

Voor de productie van koolstofnanobuisinkten is het belangrijk dat de halfgeleidende koolstofnanobuizen gescheiden worden van de metalen koolstofnanobuizen om halfgeleidende koolstofnanobuizen met een hoge zuiverheid te verkrijgen. Tijdens mijn PhD project hebben we geconjugeerde polymeren gebruikt om deze scheiding uit te voeren. Onze resultaten laten zien welke polymeren beter binden aan de koolstofnanobuizen om de halfgeleidende nanobuizen te isoleren. Door de chemische structuren te analyseren met behulp van simulaties, hebben we het mechanisme van de interactie tussen het polymeer en de koolstofnanobuizen geïdentificeerd. We hebben ook ontdekt dat de toevoeging van specifieke additieven aan de inkt de controle over de polariteit van de transistors mogelijk maakt, wat belangrijk is voor de productie van verschillende technologische toepassingen.

Van de halfgeleidende koolstofnanobuisinkten zijn we erin geslaagd om op maat gemaakte hoogwaardige veldeffecttransistoren te fabriceren. Dankzij deze kennis kunnen ze eenvoudiger en goedkoper worden geproduceerd. We hebben bovendien ontdekt dat een laag van halfgeleidende koolstofnanobuisinkt in een zonnecel de stabiliteit aanzienlijk verbetert, wat zou kunnen leiden tot een breder gebruik van zonnecellen als een bron van groene energie.
