ABSTRACT

In this study, we investigated the conductivity enhancement of calix[8]arene-multi-walled CNTs (MWCNTs) thin film. Two types of calix[8]arenes were used, which were 5,11,17,23,29,35,41,47-p-tert-butyl-49,50,51,52,53,54,55,56-oktakis[(carboxy)-pentoxy]- calix[8]arene (C[8]1) and 49,50,51,52,53,54,55,56 -octahydroxycalix[8]arene (C[8]2). The monolayer properties of these two types of calix[8]arene on water subphase were examined. Later, the thin films were fabricated by combining different ratios of each types of calix[8]arene with MWCNTs using spin coating deposition technique. Then, the developed thin films were characterized using surface potential meter and four point probe. Thin films of C[8]2 with hydroxyl groups at lower rims demonstrated higher surface potential and conductivity as compared to the thin films of C[8]1 with upper rims of tert-butyl groups and lower rims of carboxyl groups. These results indicated that the conductivity of calixarene thin films can be enhanced by MWCNTs through simple spin coating technique.

Keywords: Calixarene, spin coating deposition; conductivity; surface potential; surface pressure

ABSTRAK

Dalam kajian ini, kami mengkaji tentang peningkatan kekonduksian lapisan nipis kaliks[8]arena-nanotiub karbon multi-dinding (MWCNTs). Dua jenis kaliksarena digunakan, iaitu 5,11,17,23,29,35,41,47-p-tert-butil-49,50,51,52,53,54,55,56-oktakis[(karboksi)-pentoksi] -caliks[8]arene (C[8]1) dan 49,50,51,52,53,54,55,56-oktahidroksikaliks[8]arene (C[8]2). Sifat lapisan mono kaliksarena atas permukaan air telah dikaji. Kemudian, lapisan nipis telah dibentuk dengan menggunakan nisbah yang berbeza bagi setiap jenis kaliks[8]arena dengan MWCNTs menggunakan teknik penglitupan putaran. Seterusnya, lapisan nipis tersebut dicirikan dengan menggunakan meter potensi permukaan dan empat penduga titik. Lapisan nipis C[8]2 dengan kumpulan hidrosil pada rim bawah menunjukkan potensi permukaan dan kekonduksian yang lebih tinggi berbanding dengan lapisan nipis C[8]1 dengan rim atas yang terdiri daripada kumpulan tert-butil dan rim bawah yang terdiri daripada kumpulan karboksil. Keputusan ini menunjukkan bahawa kekonduksian lapisan nipis kaliksarena boleh dipertingkatkan dengan MWCNTs melalui teknik penglitupan putaran yang ringkas.

Kata kunci: Kaliksarena; kekonduksian; penglitupan putaran; potensi permukaan; tekanan permukaan
