Bunun tekrarlanmas\u0131n\u0131 \u00f6nlemek i\u00e7in form\u00fclat\u00f6rler k\u00f6p\u00fck \u00f6nleyici ve k\u00f6p\u00fck kesici katk\u0131 maddeleri kullan\u0131rlar, ancak bunlar\u0131n se\u00e7imi ve de\u011ferlendirilmesi, farkl\u0131 kaplama sistemlerindeki etki mekanizmalar\u0131 hakk\u0131nda derinlemesine bilgi sahibi olmay\u0131 gerektirir.<\/p>\n

Etkili bir k\u00f6p\u00fck kesici, k\u00f6p\u00fck ortam\u0131nda \u00e7\u00f6z\u00fcn\u00fcr olmal\u0131, k\u00f6p\u00fck lamellerine h\u0131zla n\u00fcfuz etmeli ve gaz-s\u0131v\u0131 aray\u00fcz\u00fc boyunca h\u0131zla yay\u0131lmal\u0131d\u0131r.<\/p>\n

Polidimetilsiloksan (PDMS)<\/h2>\n

PDMS, mikroak\u0131\u015fkanlarda bir\u00e7ok kullan\u0131m alan\u0131na sahip, ekonomik ve biyouyumlu bir malzemedir. G\u00f6m\u00fcl\u00fc cihazlar olu\u015fturmak i\u00e7in polimerlere, cam ve metal bile\u015fenlere eklenebilir; elektroosmotik pompalama membran\u0131 olarak kullan\u0131labilir ve hatta mikroak\u0131\u015fkan kanallar olu\u015fturmak i\u00e7in fotorezist kullan\u0131larak desenlenebilir.<\/p>\n

Bu sorunu \u00e7\u00f6zmek i\u00e7in PDMS oksijen plazmas\u0131 kullan\u0131larak oksitlenebilir ve y\u00fczeyinde hidroksil gruplar\u0131 a\u00e7\u0131larak silil klor\u00fcr buharlar\u0131 ile reaksiyona girerek k\u00f6p\u00fck giderici maddelerin reaksiyona girebilece\u011fi terminal gruplar olu\u015fturur. Sonu\u00e7 olarak, bu y\u00fczeyle reaksiyona giren k\u00f6p\u00fck giderici maddeler, geleneksel silikon k\u00f6p\u00fck giderici katk\u0131 maddelerine k\u0131yasla daha az k\u00f6p\u00fcklenme ve inhibisyon sergiler, ayr\u0131ca silikon muadillerine k\u0131yasla toksik de\u011fildir, da\u011f\u0131lmas\u0131 kolayd\u0131r ve termal olarak stabildir.<\/p>\n
