Karbon nanomateryaller bir\u00e7ok alanda kullan\u0131l\u0131yor<\/h2>\n

Yap\u0131lan\u00a0\u00e7al\u0131\u015fma\u00a0<\/strong>sonucunda grafen ve ticari olarak bulunabilen karbon nanot\u00fcplerden \u00e7ok daha y\u00fcksek performans g\u00f6steren karbon nanomateryaller \u00fcretildi.<\/p>\n

Grafen, karbon t\u00fcp\u00e7\u00fckler ve karbon bazl\u0131 di\u011fer nanomateryaller genellikle hem fiziksel hem\u00a0kimyasal\u00a0<\/strong>olarak olduk\u00e7a dayan\u0131kl\u0131, d\u00fc\u015f\u00fck yo\u011funluklu, geni\u015f y\u00fczey alan\u0131na sahip, iletken ve elektromanyetik dalgalar\u0131 so\u011furma \u00f6zelli\u011fine sahip maddelerdir.<\/p>\n

Bu \u00f6zellikleri sayesinde bu maddeler end\u00fcstri, t\u0131p ve elektronik alanlar\u0131nda kullan\u0131m \u015fans\u0131 bulmaktad\u0131r. Bunlara \u00f6rnek olarak kompozit maddeler, kaplamalar, sens\u00f6rler, elektrokimyasal\u00a0enerji\u00a0depolama<\/strong> gere\u00e7leri say\u0131labilir.<\/p>\n

Yap\u0131lan \u00e7al\u0131\u015fmada ucunda grafen bulunan nanot\u00fcpler elde edildi. Normalde \u00fcretilmesi \u00e7ok zor olan bu hibrit nanomateryalin sadece at\u0131k plastik kullan\u0131larak yap\u0131lm\u0131\u015f olmas\u0131 \u00e7al\u0131\u015fmay\u0131 daha de\u011ferli hale getiriyor.<\/p>\n

Yeni sistemle \u00fcretimde %90 daha az enerji harcan\u0131yor<\/h2>\n

Geleneksel geri d\u00f6n\u00fc\u015f\u00fcm i\u015flemindeki gibi tasnif ve y\u0131kama gibi i\u015flemler olmadan \u00e7al\u0131\u015fan sistemde \u00f6ncelikle plastik k\u00fc\u00e7\u00fck par\u00e7alara ufalan\u0131yor, bir miktar demir ve iletkenli\u011fi sa\u011flamas\u0131 i\u00e7in bir miktar k\u00f6m\u00fcr tozu ekleniyor ve kar\u0131\u015f\u0131m 5000 derecenin ani bir s\u0131cakl\u0131\u011fa tabi tutuluyor.<\/p>\n

Bilim\u00a0insanlar\u0131 plasti\u011fin geri d\u00f6n\u00fc\u015ft\u00fcr\u00fclmesinin normal \u015fartlarda yeni plastik \u00fcretmekten daha maliyetli oldu\u011funu belirtiyor. Bu nedenle bu konuda \u00e7ok fazla giri\u015fim olmuyor. Yap\u0131lan \u00e7al\u0131\u015fmada ise de\u011fersiz at\u0131k maddeler daha de\u011ferli maddelere d\u00f6n\u00fc\u015ft\u00fcr\u00fcl\u00fcyor. Bu sayede d\u00f6n\u00fc\u015ft\u00fcrmenin maliyeti de ortadan kalkm\u0131\u015f, hatta kar elde edilmi\u015f oluyor.<\/p>\n
