Figure 14

Mass fraction of CNTs relative to the total observed mass fraction in suspensions, 𝑊 C N T / 𝑊 O B S , at increasing energy input and different horn amplitudes: 10% (■), 20% (♦), 40% (●), and bath sonicator ( ). Dashed line, 𝑦 = 0 . 0 5 𝑥 0 . 3 3 , shows a nonlinear curve fit of the data.
