Graphene-based textile coating formulation

Product Description

ADDIGUP® S is an additive based on GUP® few-layers graphene specifically designed to provide superior physical properties to solvent borne paints and coatings while retaining mechanical properties, minimally impacting the rheological properties of the host material and without a significant increase in viscosity.

Wherever they are used,
graphene-based smart textiles
provide added value in terms
of improved performance
and comfort.

Population growth and improved living standards require solutions for textiles with new functions to meet changing needs.

When applied as a coating or integrated into yarns, graphene is thermally efficient, reducing body temperature of more than 4 °C, achieving a high range of UV protection, and preventing harmful dermatological diseases.
Graphene can be used also to enhance performance of other textiles, such as household curtains or outdoor tents and shelters, to insulate homes and reduce UV exposure when outdoors, to create antistatic carpets and for smart textiles.

Graphene application can improve the technical properties of traditional fabrics without changing their natural structure.


Graphene, with excellent thermal dispersion, can be used to provide extra thermal regulation

There is a big challenge in protecting human from extreme environmental conditions, as under extreme environmental conditions the tradition thermal protective clothing is far from enough to ensure the safety and wellbeing of human. Thus, it is important to develop new thermal insulating materials with outstanding thermal insulation performance to withstand both thermal conduction and thermal radiation.

Heat is generally transferred via thermal conduction, thermal radiation and thermal convection. The clothing system serves as the barrier between environment and human body, in which the fibrous materials and fibrous structure dominate the heat transfer from body to environment. Graphene is an extremely effective heat conductor material with excellent absorption and emission of far infrared radiation, with an high absorption for wavelengths in the range 100-281 nm and high reflection over 281 nm and provides both heating and cooling through heat dissipation. Graphene can keep the basal body temperature stable, with no strong thermal fluctuations detected in the event of changes to the surrounding temperature or physical exertion.

Antibacterial and
antiviral properties

Our formulations have been certified antiviral and antibacterial

Graphene GUP ® destroys the bacterial cell membrane with a reduction rate over 90 according to ASTM E 2149 The antibacterial function of a given finish on a textile may be used to identify three different finishing techniques Control release, regeneration, and barrier block are examples of these systems There are issues with the first two mechanisms of ending An antimicrobial agent from fabric that comes into touch with the wearer’s skin concerns the control release mechanism’s longevity after laundry These substances can irritate and cause allergies in people with healthy skin After washing, the antibacterial characteristics of fabrics treated with a regenerate mechanism are no longer activated, leading to these issues Chlorine bleach is not only bad for cotton, but it is also bad for your skin as well In contrast to the other two ways, barrier blocking with graphene does not have drawbacks In order to destroy germs that come into touch with the fabric, graphene is attached to the fabric surface and do not leach Graphene can be also used as a supporting platform for metal nanoparticle with a synergistic effect INKGUP Fabric has excellent antibacterial properties and UV protection and has been certified antiviral with “excellent effect” with the viral strain SARS CoV 2 ISO 18184 2019


GUP® used in finishing treatments gives excellent anti UV protection

In recent years, with the rapid development of industry, the ozone layer in the atmosphere has been seriously damaged Without the protection of the ozone layer, people are more exposed to ultraviolet radiation Therefore, anti ultraviolet radiation is becoming increasingly important
Textile clothing is the most effective tool to protect human body, so it is necessary to carry out anti ultraviolet finishing on textiles Some fabrics naturally have certain anti UV effect, such as wool, silk, polyester and so on Due to the benzene ring, aromatic amino acids and other functional groups in their molecular structure, they have good absorption for ultraviolet light below 300 nm However, for cotton fabric, the structure of cotton fiber does not contain benzene ring, and the longitudinal distortion is not smooth, so the ultraviolet ray is easy to pass through the cotton fabric Therefore, the anti ultraviolet finishing of cotton fabric is very important Graphene GUP® an aromatic hydrocarbon molecule composed of a (infinite sheet of fused benzene rings (or sp carbon atoms bonded in fused hexagons) has the advantages of high refractive index, strong UV shielding ability and photocatalytic effect Therefore, if combined with cotton fabric, it can improve the anti UV performance of the fabric and protect people from ultraviolet radiation

Abrasion resistance
and durability

GUP® formulations enable a longer lifetime for textiles

The increasing production of protective equipment that requires increased security for work in harsh operating conditions has led to the need of fabrics with high resistance to wear Protective clothing for workers, soldiers, police officers, firefighters and others is exposed to daily wear and in specific areas (shoulders, knees, the edges of legs and the like so it is necessary that it is highly resistant to abrasion Wear is only one of the factors that influence the shabbiness i e the durability of the fabric This resistance to abrasion is important because it enables a longer lifetime when wearing clothes It is similar to surface products for bedding, furniture and technical purposes GUP® formulations for textile coatings have been tested (UNI EN ISO 12947 1 2 and proved to have high abrasion resistance on several kind of fabrics

EMI Shielding and
Electrical Conductivity

GUP® used in finishing treatments for high demanding smart textiles

Electrically conductive textiles make it possible to produce interactive electronic textiles They can be used for communication, entertainment, health care, safety, homeland security, com putation, thermal purposes, protective clothing, wearable electronics and fashion Conductive textiles that change their electrical properties as a result of a physical variable can be considered a sensor Textile sensors can be designed to measure temperature, biopotential ( myographs, encephalographs), acoustic ( lungs, digestion, joints), ultrasound (blood flow), biological, chemical, motion ( pressure ( radiation ( spectroscopy), odor sweat, mechanical skin parameters, and electric skin parameters INKGUP Fabric and GUP C Paste help to have coatings with very low resistivity and find applications in smart wear, workwear, heating devices and EMI shielding textiles

ADDIGUP® S is added to the host material to be processed. The product should be stirred well before use. The recommended loading range of ADDIGUP® S is in the range 5-10 wt% calculated on the weight of the host material. The optimum dosage level should be determined with specific test based on the required performance, host matrix characteristics, processing conditions and presence of other fillers.
