Sept 5 FTIR-DSC continued
- Group Members Andrew Farag Sr (Undergrad) and Michael Bible Jr (Undergrad)
- Group Name : AMT
Objective
- ALL groups will continue their film synthesis from the last week. And ALL groups will start new film syntheses (PVA only and PVA with 10% sodium montmorillonite)
- Groups A* and B* will be using the UV-Vis to make calibration curves for malachite green absorbance and to determine the equilibrium of their malachite green/dye samples
- Groups C* and D* will take a powder X-ray diffraction of one (or two) of their films. They will take Fourier Transform Infrared Spectra (FTIR) of all of their films. They may (time permitting) perform differential scanning calorimetry (DSC) of all of their films.
My group was assigned to use the FTIR and DSC
Note: On Friday Groups A and B will perform the tasks Groups C and D perform on Wednesday and vice versa.
Description
- FTIR
- We will be using attenuated total reflectance (ATR) mode for our samples
- Place the film in the sample holder. Execute measurement
- Save measurement data onto thumb drive
- DSC
- DSC analysis will be set up to run over night

Data
Figure 1. Shows the FTIR data for the polymer-only samples that were soaked in MG solutions.
Figure 2. Shows a close-up view of the region of the FTIR graph that presented the most separation between sample readings.
Figure 3. Shows the FTIR data for the polymer + clay samples that were soaked in MG solutions.
Figure 4. Shows a close-up view of the region of the FTIR graph that presented the most separation between sample readings for the polymer with the clay.
