Part I. Absorption of SWNT ink in cotton and fabric 10 mg/mL SDBS surfactant is dissolved in DI water with the help of bath sonication. Then, laser ablation SWNTs are dispersed in the surfactant solution with 0.8 or 1.6 mg/mL concentrations. After bath sonication for 5 minutes, the CNT dispersion is probe-sonicated for 30 minutes at 200 W power (VC 505, Sonics Inc). Then a fluffy cotton sheet (Cloud 9 dream fleece, Wal-Mart Inc) with thickness of ~1-2 mm is dipped into the SWNT ink and immediately removed. The mass of the ink is obtained by the weight difference before and after the soaking of the cotton sheet. This process is repeated to increases the SWNT loading in the cotton. The same procedure is repeated with a fabric sheet (TX309, The Texwipe Company LLC). Fig. S1 shows the accumulated ink mass absorbed per cm2 by the cotton or the fabric with different numbers of soaking times. A small variation (
