Entry title

Purpose: To continue the experiment from 05/19/14, this time adding the NH4-CNC 6.2% by weight to ABS and PLA to make 1%, 5%, 10%, and 20% by mass mixtures.

Safety and Procedure: See 05/19/14

Experimental:

 Mass %	Mass NH4-CNC	Mass ABS
 1.0%	0.0105 g	0.9898 g
 5.0%	0.0501 g	0.9508 g
 10.0%	0.0994 g	0.9010 g
 20.0%	0.2008 g	0.8004 g

When the NH4-CNC was suspended in acetone the solution turned a milky white color.

 Mass %	Mass NH4-CNC	Mass PLA
 1.0%	0.0101 g	0.0000 g
 5.0%	0.0503 g	0.0000 g
 10.0%	0.1006 g	0.0000 g
 20.0%	0.2000 g	0.0000 g

When the NH4-CNC was suspended in dichloromethane the NH4-CNC did not break up at all, large chunks remained even after two hours of sonicating. The solution was therefore vacuum filtered and the NH4-CNC removed to be used again.
