This document presents a project on developing UV protective cellulose-based clothing using graphene oxide. The project aims to prepare graphene yarn/fabric comprising reduced graphene oxide and natural cellulose, and check its response to ultraviolet radiations. Graphene oxide will be incorporated into cellulose through dip coating or chemical reduction to impart UV protection. Previous studies have shown graphene oxide can form a barrier to UV light and improve cellulose's UV shielding abilities when combined. The work plan involves producing graphene oxide flakes using the Hummers method and incorporating it into cellulose under varying parameters to develop a UV protective textile.

3. UV PROTECTION:
• Owing to depletion of the ozone in the Earth's atmosphere, there
is progressive increase in ultraviolet radiation on human skin.
• UV radiation from the Sun or artificial source causes
photodermatosis, acceleration of skin aging and changes to the
functioning of immune system.
• Making textile which can absorb or scatter UV radiation can be a
boon for human existence.
• The UV-protective properties of cellulose can be improved by UV
absorbers.

4. UV SHIELDING using “GO” :
• Recently, Moraes et al. reported a UV-shielding composite film based on
graphene oxide (GO) and cellulos acetate (CA).
• GO (graphene oxide) is a monolayered structure material which has
superior UV absorbing property due to its honeycomb structure.
• It possesses good absorbance of UV light at wavelengths between 250nm
and 350nm.
• Graphene's optical nanomaterials for optoelectronic and nanophotonic
owing to their unique optical properties.
• Graphene have excellent flexibility and mechanical strength. Thus,
graphene can be ideal for flexible UV photodetectors.

6. Why Cellulose based Fibre?
 Chemical modification of cellulose based fibre can be easily carried out due to the presence of
the three hydroxyl groups in each anhydroglucose unit.
 Cellulosic fibre can be directly used wherein the polymer chain will be attacked to make it
suitable for reacting directly, it can be grafted with monomer having a phase change polymer
chemically attached thereto.

8. HOW UV PROTECTIVE MATERIAL WORK?
Most fabric that we wear are consist of loose
weave and visible light can penetrate through it
to our skin .
In UV protective clothing we make change in
weave to make special fabric that act as a
barrier

9. PROJECT AIM:
To prepare graphene yarn/fabric comprising
reduced graphene oxide and natural cellulose.
Checking resultant yarn's/fabric's
response to ultraviolet radiations.

10. PREVIOUS STUDY REVIEWS:
 The morphology of GO was investigated previously which showed a tendency to self
assemble and form multilayer sheet including wrinkles.
 Earlier studies reported sharp and bright diffraction spots for single layer of GO through
X ray diffraction which turned into ring patterns for polycrystalline aggregates.
 UV treatment of materials with GO results slightly yellowish but highly stable and
flexible film. Reduced GO in the cellulosic matrix is qualitatively confirmed by solid
colour change to black.
 Improvement in electrical conductivity is seen as the number of GO coating increased
owing to the presence of several oxygen containing group and intrinsic structural defect

11. WORK PLAN:
• Graphene oxide flakes is to be prepared from graphite by Hummers
method. Graphite powder immersed in conc. Sulphuric acid under an
ice bath, then adding chemicals like potassium permaganate.
• Incorporation of graphene oxide on cellulose can be done either by
dip coating or chemical reduction or both (under favorable
parameters).
• After GO coating, resulting sample is to be rinsed with DI water to
remove excess cross linking agents. Then drying the sample under
steam.
