Summary for powder density Discussion
The thread asks how to measure powder density for carbon nanotube powders before and after electroless nickel and copper coatings in a metal matrix composite study. Jagannatham Manda of Chennai, India says he is working on the coatings and wants the density of the CNT powders before and after plating. No definitive technical method is given in the thread. Guillermo Marrufo offers a tentative idea: use controlled flotation in media with known densities, while carefully avoiding surface tension effects and trapped bubbles. He explicitly notes that he is not sure of the subject and is only risking an informed guess because the question had gone unanswered. The discussion therefore provides only a cautious suggestion rather than a confirmed procedure, and readers should treat the flotation approach as an unverified lead rather than established advice.
Q. Sir,
I am PhD student. I am doing electroless nickel and copper coatings on carbon nanotubes for metal matrix composite applications. I would like to know the density of carbon nanotube powders before and after the electroless coatings.

A. I really don’t know anything about the subject but since nobody has answered your question in almost a month I will risk my ignorant idea. Controlled flotation in different media with known densities. Obviously surface tension and trapped bubbles would have to be totally avoided.
