Short Purified MWCNTs, -COOH functionalized (TNSMC1)

Product Code: CNB-8-TNSMC1

Timestub^TM --Short-length High purity Multi-walled carbon nanotubes---have three kinds of products: TNSM1, TNSMH1 and TNSMC1. TNSM1 is produced by mechanical cutting TNM1, followed by dis-agglomeration treatment. TNSMH1 and TNSMC1 are the TNSM1 hydroxyl and carboxyl functionalized products, respectively. TNSMH1 and TNSMC1 are prepared by KMnO₄ oxidation in H₂SO₄ solution at different temperature and different KMnO₄ concentration.
