Zyvex 101 - Basic Information

Q1. What is a composite?

  • A reinforcing fiber made up of two or more substances in a resin matrix whose cumulative properties are greater than the individual materials.

  • Composite materials are made up of two or more different materials that remain distinct after combining, creating a new material with properties that can not be achieved by acting alone.

Q2. What is nanotechnology?

  • The word “nano” in nanotechnology derives from the term “nanometer”, which is one-billionth of a meter. Molecular nanotechnology is the manipulation of matter at the atomic or molecular level (on the length scale of approximately 1-100 nanometers). Materials that are characterized by structural features less than 100 nm can be broadly classified as nanomaterials and serve as the basis for the products we create.

  • Zyvex currently utilizes both carbon nanotubes (CNT) and graphene nanoplatelets (GNP). Carbon nanotubes are small cylinders of carbon atoms and are understood to be among the strongest materials known to man. Graphene nanoplatelets are a relatively new class of carbon nanomaterials and offer different properties when compared to carbon nanotubes.

  • Zyvex is the leader in developing chemistry solutions that unlock the potential of carbon nanomaterials into various products, including composite carbon fiber, thermoplastics, and adhesives.

Q3. What is prepreg?

  • Pre-impregnated composite fibers, where a material, such as epoxy is already present and optimally distributed around the fibers. Prepreg is defined by the weave of the fabric, which can give it different properties, such as strength and conformability. By manipulating these weave patterns, prepreg can exhibit an array of advantages that can be applied to many industries. It is sold by the roll and then formed into a mold for production.

Q4. What are carbon nanotubes?

  • Carbon nanotubes, or CNTs, are 100 times stronger than steel at one-sixth the weight, and when properly added to products can help them become lighter, stiffer, and stronger. CNTs are electrically and thermally conductive. CNTs are also “phobic” to almost everything, so they need to be coerced into resin systems. Zyvex has developed our Kentera™ technology  that makes CNTs compatible with resins, thus opening the door to many new products and processes. For perspective on the size of carbon nanotubes, visit NASA's 'Scale of the Universe' site and zoom all the way in to 10^-8.8.

Q1. What makes Zyvex carbon nanotechnology better than carbon nanotube or graphene additives?

  • Zyvex Technologies' Kentera™ technology  unlocks the complete potential of CNTs and GNPs. Our technology helps in making CNTs and GNPs useful; otherwise it is very difficult to process CNTs and GNPs because of their small size and high surface area. 

Q2. How does Zyvex functionalize carbon nanotubes and graphene?

  • CNTs and GNPs are non-covalently functionalized using rigid-rod conjugate polymers called Polyphenylene Ethynylenes (PPEs). The interaction of PPE backbone and CNTs and GNPs is through pi stacking the side chains providing suitable functionalities for both compatibilizing and adhesion to the host marix.

Q3. What impact does Kentera have on the electrical properties of carbon nanotubes and graphene?

  • Kentera™ is a semiconducting polymer, which generally will result in decreased electrical conductivity.
