BNNT Products

NanoBorNT(means 쏝orn to Nano)
NanoBorNT is a trademark for Naieel Technology셲 BNNT product.
High quality BNNT products are currently available with 80 wt% purity (NanoBorNT-80) and 90 wt% (NanoBorNT-90) purity, respectively. Naieel Technology셲 BNNT products are world renowned in their superior quality as well as industrial applications in addition to the cheapest prices among others.

High Concentration of BNNT Dispersed Polymer Resins

We developed the high concentration of BNNT dispersed polymer resins first ever in the world. We wish this product will enhance the industrial applications of BNNT as follows; easy mixing (just mix the product with your target polymer systems), versatile (many different types of polymer resins are available), enhanced material properties, and economic, etc.

BNNT dispersed Solvents

High concentration of BNNT is dispersed in various solvents with enhanced dispersion and stability. We wish these products will enhance the industrial applications of BNNT as follows; easy mixing (just mix the product with your target polymer systems), versatile (many different types of solvents are available), and economic, etc.

Structure of BNNT

Fundamental crystallographic structure of BNNT is same with CNT, hexagonal planar layered hollow nanotube, except for the constituting atoms. Naieel Technology셲 BNNT is cylinder typed multi-walled with the outer diameter of 30~50 nm in average, and the length with 10 um in average. The ends of most BNNT are opened without nodes inside. Based on Raman spectrum, it is assumed that most BNNT are armchair structured while some are zigzag structured (Please contact us for more information for Raman property of our BNNT).
  • Zigzag
  • Amchair
  • Chiral

There are three structures of BNNT.(amchair, zigzag, chiral)
