Komposit CNT-TiO2 untuk dilapiskan pada diaper telah disintesis dan diuji kinerjanya untuk penyisihan ammonia dan jamur Candida albicans sebagai penyebab bau dan kandiasis pada diaper. Komposit dikarakterisasi dengan FTIR, FESEM-EDX, XRD, dan UV-Vis DRS. Hasil Karakterisasi menunjukkan bahwa komposit memiliki kristalinitas tinggi dan band gap rendah. Hasil uji penyisihan menunjukkan bahwa komposisi komposit optimum adalah 1-3% massa CNT dan 97-99% massa TiO2. Treatment asam CNT dan pembuatan komposit pada pH 1 menggunakan sonikator merupakan teknik pembuatan yang optimum. Penyisihan ammonia selama 2 jam berhasil mendegradasi 91% ammonia. Penyisihan jamur dengan TiO2 P25 berhasil mendisinfeksi 98% jamur selama 2 jam. ......CNT-TiO2 composite that is coated on diaper had been synthesized and used for ammonia and Candida albicans removal that cause odor and Candidiasis on diaper. Composite was characterized by FTIR, FESEM-EDX, XRD, and UV-Vis DRS. Result of characterizations show that composite has high crystallinity and low band gap. Result of removal experiment show that the optimum composition of composite were 1-3% mass of CNT and 97-99% mass of TiO2. Acid treatment CNT and synthesize of composite in pH 1 by using sonicator is an appropriate synthesize. Ammonia removal had been done for two hours and reached 91% degradation of ammonia. Disinfection by TiO2 P25 had reached 98% disinfection of yeast for two hours.

Carbon Nanotubes-Titania (CNT-TiO2) composite that coated on diaper have been synthesized and tested for the removal of ammonia (self-cleaning test) and Candida albicans fungi (self-sterilizing test) that cause odor and make Candidiasis disease, respectively. The composite was characterized by FTIR, FESEM-EDX, XRD, and UV-Vis DRS. XRD and UV-Vis DRS results showed that the CNT-TiO2 composite has a high crystalline and low band gap. The results of 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 TiO2. Acid treatment at pH 1 were accompanied by ultrasonic agitation is an appropriate conditions on the composite synthesis. Within 2 hours of testing the modified diapers, the optimum composite can remove ammonia and Candida albicans by 91 and 98 %, respectively. Based on the experiment results, ammonia and fungi on the modified diapers was able to be removed up to minimum standard to prevent odor and diaper rash
