Purpose: To create more plastic casting samples using Na-CNC 6.2% weight in both ABS and PLA.
Safety and Procedure: see 05/19/14
Mass % Mass NH4-CNC Mass PLA 5.0% 0.0504 g 0.9489 g 10.0% 0.1004 g 0.9001 g 20.0% 0.2011 g 0.8001 g 30.0% 0.3018 g 0.7987 g 35.0% 0.3514 g 0.6504 g 40.0% 0.3997 g 0.6009 g
The NH4-CNC did not suspend completely in the dichloromethane, there were still small pieces visible when the PLA was added.
Mass % Mass NH4-CNC Mass ABS 30.0% 0.3011 g 0.7009 g 35.0% 0.4001 g 0.6511 g 40.0% 0.3510 g 0.5988 g
There was an accumulation of NH4-CNC on the bottom of the vial before adding the ABS. To remedy this the vial was manually shaken to make a homogeneous mixture before placing the ABS beads in.
All the NH4-CNC samples in their respective solvents were placed in the sonicator at 10:25 AM and allowed to sonicate until 3:30 pm. The vials were then removed and the plastic beads added. The vials were sonicated again from 3:35 pm to 6:15 pm.
