Tasks for September 10
Completion of Film SynthesisContinued from Dr. Harting's procedure
Film preparation of ionic liquid modified clay
DSC (Differential Scanning Calorimetry) DataNote: To calculate mass of water evaporated the following equation was used: q=mHv. So that mass of water=(q×mass of sample)/Hv where Hv=2.23×103 J/g<br.> PVA film in 2 ppm MG solution<br.> <br.>
