Pengaruh Penambahan Polyvinyl Alcohol Dan Calcium Silicate Terhadap Sifat Kimia-Fisika Elektronik Tekstil Berbasis Lenzing™ Lyocell (STD) Dan Very Few Layer Graphene

IKHA SETYA AMINATI / 1810246952 - Nama Orang;

Lyocell is the newest generation of cellulose fibers. The development of
textile product value and technology today is heading towards the creation of
electronic textiles (E-Texile) which aims to incorporate electrical function into
textiles. The results of the E-Texile field will be commercial product expansion
with applications becoming smart clothes, sensors, flexible conductive devices,
and others. The growth of electronic textiles (E-Texile) in the next 10 years will
develop with an estimated growth of 5 billion USD in 2032. The first generation
of E-Texile was made by coating the fabric with particles to give conductive
properties to textile fibers. However, metal materials have some weaknesses, one
of which is the stiff nature that makes E-Texile uncomfortable to wear. Because of
issues and concerns with metal materials, and the demand for clean energy in ETexile
devices, the use of Very Few Layer Graphene (VFLG) can be one of the
options currently being developed. VFLG, which is made up of hexagonal carbon
atoms, makes it have lighter, stronger, and more flexible properties. Therefore,
the creation of Lyocell-based electronic textiles and Very Few Layer Graphene
(VFLG) becomes a potential product because of the advantages it produces. In
this research, additives will be added as VFLG adhesives on the Lyocell surface
in the form of Polyvinyl Alcohol (PVA) and Calcium Silicate (CaSiO4). The fixed
variables used are the size of the fabric per sample 3 x 3 cm, the volume of
conductive ink 20 ml, the drying temperature of the fabric 100oC, the drying time
of the fabric for 10 minutes, the number of dyeing cycles 6 times, and the dyeing
time for 5 minutes. Variations in the ratio of additive concentrations and the
number of washing cycles are done to determine the optimum conditions and
VFLG resistance on Lyocell. The results show that electronic textiles based on
Lyocell and VFLG after adding PVA and CaSiO4 additives have a pH range of
6.9 - 8.1. Lyocell with VFLG additives has been proven to produce the best
surface resistivity value of 92.4 kΩ/sq on the variable of Lyocell + VFLG without
washing. The maximum washing cycle of Lyocell with VFLG additives in this
research can only be done once, as based on visual analysis/digital image of the
fabric which shows that the addition of PVA and CaSiO4 additives has not been
able to function as a VFLG coating on the surface of Lyocell textile. VFLG is
detached from the fabric surface as the number of washing cycles increases
because of the weak physical bonding of VFLG to the Lyocell surface. The FTIR
spectrum confirms that there is VFLG on the Lyocell surface with VFLG additives
that is detected from the presence of stretching C = C at 1631 cm-1. This value
indicates the presence of double carbon bonds that represent the core graphene
on the surface of Lyocell and VFLG-based electronic textile samples.
Key Words : Very Few Layer Graphene, Electronic Textile, Lyocell, Conductive.
