Carbon nanotubes (CNTs) have great potential to improve the strength and toughness of traditional cementbased building materials. After effective dispersion in water with a surfactant, followed by separation using a centrifuge, multi-walled carbon nanotubes (MWCNTs) can be stored stably for over three...
Trace amounts of antibiotics in water can accumulate in the human body through the food chain, posing significant health risks. Therefore, there is an urge

The GelMA-coated CNTs were well dispersed in the prepolymer solution without any evidence of aggregation as shown in Figure 2 (a) with a more uniform dispersion compared to a previous study of single-walled carbon nanotube (SWNT) loaded collagen I-Matrigel™ composite scaffolds (concent...

3 g of CNTs were refluxed in 225 ml of mixed concentrated nitric (68%, 168.75 ml) and sulfuric (97%, 56.25 ml) acid at 130 °C for 30 minutes. This step leads to the creation of acidic sites on the surface of the nanotubes, improving CNT dispersion and stabilisation...
0.1 g CNT (diameter: 10–20 nm, length: <10 μm, Chengdu Organic Chemistry Co. Ltd) were firstly dispersed in 40 ml of deionized water using ultrasonic dispersion for a period of 30 min. Then, the CNT suspension was gradually added to the diazonium salt solution and stirred for 10 ...
Methods Section Strain sensor fabrication. CNTADH, surfactant and water are put into a test tube and treated by a sonicator for 20 minutes. Surfactant is from commercial detergent. The dispersion is filtrated by a com- mercial wire screen filter to remove large particles. Filtrated ...
To assure better dispersion of CNTs in PVA, the CNTs are treated by acid before using. As shown in Fig. 2b, the rougher surface of PVA/CNT film compared with that of pure PVA film could be confirmed, indicating the blending of CTNs. Fig. 2 SEM images of pure PVA film (a) and ...
