QS got involved in the research and development of graphene 6 years ago and focuses on the study of graphene based special bres. Now, major breakthroughs have been made in research and development of graphene based special bres. And the advent of our graphene based special bres will subversively change safety protection materials and safety protection concepts of the world.
Graphene is a kind of nano-sized carbon materials. And it is the most important and leading edge material that possesses excellent properties beyond imagination.
The structure of Graphene is a two-dimension crystal with one layer of atomic carbon, and its theoretic thickness is only 0.34 nm. The thickness of 20 thousand layers stacking graphene sheets is just equal the diameter of human being' s hair. The theoretical specic surface area of graphene is up to 2630 m 2 g-1
It has outstanding thermal conductivity (~5000 W m -1 K -1 ), as well as high speed electron mobility (~200 000 cm 2 V -1 S -1 ) at room temperature. This is the 3 times and 10 times than that of the pure diamond and copper. Graphene is a superior strong material ever measured in the world. It is noticed that the graphene density is even harder than diamond and about 100-300 times stronger than steel. Its mechanical stress reaches to 130 GPa and the breaking tenacity reaches to 42N/m 2 , while the density is only 2.2 g/cm 3 .
Single layer graphene is completely transparent and the light transmittance reaches to 97%. It is an outstanding current-conducting materials that the electrical resistivity of graphene is 10 -6 Ω·m which is lower than copper and silver in the condition of room temperature. Graphene has very promising applications in eld-eect transistors, lithium ion batteries, fuel cells, molecular sensors, actuators, ultra-capacitors, high performance polymer composites and so on.
The discovery of fullerenes in 1985 and the discovery of carbon nanotubes in 1991 had attracted a great amount of research attention all over the global. Since experimentally discovered in 2004, graphene with unique properties has become one of the most exciting materials today, Professor Andre Geim and his posdoctoral Konstantin Novoselov at the University of Manchester won the Nobel Prize in Physics in 2010 "for groundbreaking experiments regarding the two-dimensional material graphene" .
QS has successfully developed a series of graphene based special bres,
such as graphene-PET, graphene-PAN and graphene-PVA
nanocomposite bres.
After testing, the characteristics of these bres show super and excellent
performance. Graphene based special bres can tensile reinforcing bres,
cut-resistant and abrasion resistance at the same time, with
anti-corrosion, antiaging, antibacterial, antistatic, heat-resistant, ame
retardant, anti-ultraviolet and have far infrared properties. And the special
products of QS i.e. graphene KYORENE special bres also have a
conductive function.
Also, QS has developed by itself the most
up-to-date manufacturing machines of graphene,
and could produce graphene with the name of
KYORENE. The KYORENE graphene not only has an
excellent performance but also a low cost which is
only twenty percent of the similar products of
research institutes of the world. And this paves the
way for large-scale and low-cost production,
promotion and application of graphene.
In consideration of the unique properties of graphene, QS is the rst
company that researches and develops graphene based special bres
and pushes applications of graphene in the eld of safety protection.
1. The cut-resistant and heat-resistant gloves which were made from
KYORENE Graphene-PET nanocomposite bres have low prime cost.
And the prime cost is only 20% of current aramid bres and the
European PE gloves on the market and 40% of Chinese PE bre gloves.
High performance and low cost graphene bre will fundamentally
change the current safety protection areas of cut-resistant gloves,
sleeves, and other products.
2. KYORENE Graphene-PET
nanocomposite bres not only
have antibacterial function but
also have sterilization, deodorant
function. It could be applied in
protective clothing, helmets,
protective masks and other
products. Also, it can be applied
in antibacterial medical bed
mattress and sheet, safety shoes
and insoles with the performance
of anti-friction, permanent
antibacterial and deodorant.
3. KYORENE Graphene-PAN nanocomposite bres could replace part of
the production of wool blankets and carpets fabrics. It can be used as
outdoor fabrics, such as ski jackets, sails, military canvas tents with
wear-resistant, antistatic and antibacterial properties. The graphene
based bre materials can be used on wigs with the performance of
breathable, antibacterial, smooth, anti fracture and easy shaped. And
the prime cost is only one third of general wigs.
4. KYORENE Graphene-PVA nanocomposite bre can be widely applied
in the elds of water conservancy dam, highway and bridge
construction, greatly improving the concrete tensile strength and
tensile strain. High strength and high modulus graphene-PVA bre
could be used in water conservancy construction, instead of steel as
reinforcement strain belts.
5. Also, it is used as a reinforcing
material of plastic products for the
manufacturing of much safer and
lighter anti-riot helmets, radial tire or
diagonal tire cord, rubber reinforcing
materials, conveyor belt, re hose,
braided hose, etc. And the
Graphene-PVA nanocomposite bres
can be used to make canvas,
tarpaulins, conveyor belts, shing nets
in the industrial eld. Graphene-PVA
namocomposite bres also can be
made into a high-performance
engineering plastics.
In addition to above KYORENE Graphene based nanocomposite special
bres, now QS is developing other high-performance composite bres,
such as Graphene-PA nanocomposites bre, Graphene-PU
nanocomposites bre and Graphene-PPTA/PMIA nanocomposites bre.
The Graphene-PA nanocomposites bre, which is the key research
project of QS, could be used for manufacturing high-performance and
low-cost automotive air-bag. And the prime cost of air-bag of
Graphene-PA nanocomposites is only 20% of the general products. QS
also plans to use KYORENE special bres in many military products,
which will cut down the cost of them and largely improve the
performance of military equipment as well.
It is the rst time that QS releases
KYORENE special bres in safety protection
elds. In order to realize the revolutionary
change of the bre materials of safety
products, we hope to cooperate with
manufacturers, research institutes and
franchisers to develop and market a series
of graphene based special bre products
on a win-win basis.
