Birla looks to nano with Chasm deal
Carbon black producer Birla Carbon and Chasm Advanced Materials, a US-based specialist in printed elec- tronics materials and battery materials, have agreed to develop and manufac- ture hybrid nanomaterials based on carbon substrates and carbon nanotubes. These will be targeted at multiple market segments, including
tyres, batteries and coatings. “The combination of Chasm’s
expertise in nanotube enhancement and our deep knowledge of carbon substrates and applications offers us the chance to rapidly advance our understanding of these high-perfor- mance, scalable nanomaterials,” said Birla Carbon CEO Dr Santrupt B Misra
have worked to develop formulas that maintain transparency, says Ali.
Opportunities in 3D print Most recently, XG Sciences announced a collabora- tion with Illinois, US-based 3D printer filament company, Terrafilum Engineered Filaments, to develop 3D printing filaments containing graphene for fused filament fabrication (FFF) or fused deposition modeling (FDM) printing. Limitations of FDM include direction-specific structural weakness and slow processing speeds. The graphene additive is expected to help resolve both of these problems—improved thermal conductivity allows faster processing, improved part strength overall, and enhanced z-direction strength in particular, which allows higher builds, says Ali. The project partners say that, because graphene also provides ESD properties, it can address a currently unmet market need for robust ESD filaments. Meanwhile, Swedish companies Graphmatec
(which recently opened a factory for graphene solutions) and Add North 3D (a 3DP materials developer) last month introduced Koltron G1, an FDM 3D printable filament material made with Graphmatec’s Aros Graphene. The companies say

the filament is electrically and thermally conduc- tive, flame retardant, and has high mechanical and chemical resistance. The graphene also gives printed parts self-lubricating properties. Target applications include EMI/RFI shielding and wear- able and printable electronics. At the NAUM ’19 conference, Lehvoss Group described its 3D print compounds made with graphene nanotubes, which it says are the first conductive laser sinter materials in the market. The materials are suitable for powder bed fusion and FFF 3Dprint systems, with potential applications including trays, housings, and medical equipment. Elsewhere in the 3D print world, Finland’s
Carbodeon has partnered with UPM Biocompos- ites, which has factories located in Finland and Germany, to produce 3D printing compounds based on UPM’s cellulose-PLA biocomposite containing Carbodeon’s nano-diamond additive. The nano- diamond additive is said to improve printing speed and properties, including stiffness, strength, and heat deflection temperature. The companies are develop- ing filaments for fused filament fabrication and granules for large-scale fused granular fabrication.
