Synthesis of Carbon Nanotube–Titania Composite for Application in a Self-cleaning Self-sterilizing Diaper

Abstract

A carbon nanotube-titania (CNT-TiO 2 ) composite that coats diapers has been synthesized and tested for the removal of ammonia (self-cleaning test) and Candida albicans fungi (selfsterilizing test), which cause unpleasant odors and candidiasis disease, respectively. The composite was characterized by FTIR, FESEM-EDX, XRD, and UV-Vis DRS. Results of XRD and UV-Vis DRS measurement showed that the CNT-TiO 2 composite has a high crystalline and low band gap. The results of the self-cleaning and self-sterilizing tests showed that the optimum composition of the composite was 1-3 wt% of CNT and 97-99 wt% of TiO 2 . Acid treatment at pH 1 was accompanied by ultrasonic agitation in appropriate conditions for composite synthesis. Within 2 hours of testing, the modified diapers, at the optimum composite composition, can remove ammonia and C. albicans by 91% and 98%, respectively. The experimental results showed that ammonia and fungi on the modified diapers were removed up to the standard minimum values required to prevent odor and diaper rash.

“…Another study has used a doped metal oxide such as C-N-titania (Slamet et al, 2017). In fact, its composites, such as CNTs-titania have also been utilized for such applications (Wibowo et al, 2015).…”
