Figure 8

Scanning electron microscopic photographs of carbon nanotubes and asbestos fibers in suspension. Photographs were taken from liquid formulations of CNT in medium according to Porter (physico-chemical characterization in pre-trials). CNT agglomerates occurred infrequently and are not visible here. A: MWCNT A (left: 10,000×, right: 30,000×). B: MWCNT B (left: 10,000×, right: 30,000×). C: MWCNT C (left: 10,000×, right: 30,000×). D: MWCNT D (left: 10,000×, right: 30,000×). E: Long amosite asbestos (left: 2,000×, right: 7,000×).
