Title: | Multifunctional Composites with a polymer matrix filled with carbon nanotubes for technical and medicalpurposes |
Type of product: | Release of new product: materialIssue new products: materials. Nanosized carbon filler - multiwall carbon nanotubes for composite materials based on polypropylene (PP), polytetraftoretylenu (PTFE), polyethylene (PE) and exfoliated graphite (TEG) (CNT fiber-filled PP, as suture material for surgery; bearingsPTFE-15% CNTs TEG-0.1% CNTs stuffing etc. |
Description: | It was developed effective methods of homogenization CNTs in liquids of different nature. It based on the simultaneous action of shear deformation and cavitation stirring, and allows further obtain composites with high homogeneous distribution of CNTs in the matrix. |
Technical advantages: | Reinforcement of polymeric materials even at low concentrations of carbon nanotubes determine their crystal structure and affects the physical properties of nanocomposites. This increases the conductivity by several orders, the system doubles the strength PTFE-CNT. The strength and uniformity characteristics of PP-CNT fiber is the best world analogues. Temperature thermooxidative degradation PE-CNT increases by 60 0С. For a system TEG-0.1 wt%. СТЕ durability of materials increases at least twice, and the elastic deformation range by 40%. |
The economic benefits: | High parameters CNT-filled composites reach for their small concentrations (a few tenths of mass percent). Therefore, a significant improvement of performance of these products is achieved at low cost. So the life of the seals made from a material TEG-0.1 wt%. CNT doubled. Implementation of the technology in mass production is constrained by lack of Ukraine exclusively industrial PTFE, primary PP, PE and so on. |
The impact on the environment. Environment: | Using materials developed increases in machine overhaul lifetime of equipment, thereby decreasing energy and labor costs.
The filler for polymer and other matrices - CNT agglomerates carbon material is graphite-like lattice is thermally, chemically and radiation resistant, biologically inert that is environmentally friendly. |
The stage of completion: | PrototypeResearch Party: bearings with PTFE-CNT, seal with a stuffing TEG-CNT (specifications interim technical specifications); prototypes PP-CNT fibers (project specifications) |
Implementation: | not implemented |
