dc.description.abstract | Textiles have an important role in the health sector. Recently, textiles have received
special attention in the midst of the Covid-19 pandemic that began in 2019. Medical
personnel are concerned about the potential for contamination from viruses or
bacteria on the clothes they use in hospitals.This research aims to (1) analyze the
optimal method for synthesizing Oil Palm Boiler Ash (OPBA), Titanium Dioxide
(TiO2), and chitosan nanoparticles; (2) analyze and develop nanocomposites as
coatings on fabrics; and (3) analyze the antibacterial self-cleaning performance of
fabrics coated with nanocomposites. The Ball mill and coprecipitation methods are
used to synthesize OPBA nanoparticles while the sol-gel used to synthesize TiO2 and
prepare the nanocomposite, which was used to coat fabrics using the dip-coating
method. The results show that the optimum method for synthesizing OPBA is the
coprecipitation method, which produced a crystal size of 15 nm with a SiO2 content of
48.5%, the TiO2 obtained is a rutile phase with a crystal size of 70.25 nm, and chitosan
has an orthorhombic crystal system with a size of 4.15 nm. The nanocomposites
coatings showed significant results, this is observed from the morphology of the fabric
before coating that shows the typical parallel grooves of textile fabric. However, the
coated textile surface seems rougher, indicating the presence of nanocomposites.
Coffee stains dripped on the protected fabric fades within 4 hours. Based on the
contact angle test, the surface of the coated fabric is hydrophilic. For the purpose of
materials with self-cleaning properties surface coatings are efficient in self-cleaning.
Meanwhile, the antibacterial test showed that there were no bacterial colonies on the
coated fabric. | en_US |
