Thermal analysis (TA) is a group of analytical techniques that used
to analysis the time and temperature at which physical or chemical
changes occur when substance is subjected to cooling or heating.
It is used to measure some properties of textile fibers.
Thermal Analysis?
3
Common Thermal Analysis Techniques
4
Differential Mechanical Analysis (DMA), Modulus
Thermo Gravimetric Analysis (TGA), Mass
Differential Scanning Calorimetery (DSC), Heat flow
Thermo Mechanical Analysis (TMA), Dimension
Differential thermal analysis (DTA), Mass and Heat flow
Theoretical background of DSC
The difference in heat flow to the Specimen and Reference at
the same temperature is recorded as a function of temperature.
Provides heat flow in to sample and out of sample.
Temperature range from -120 to 725◦C.
Differential scanning calorimetry(DSC)
5
Endothermic heat flow? Tg, Tm, Evaporation
Exothermic heat flow ? Tc, oxidation, cure
What Type of technologies DSC use?
1. Heat flux DSC
The test sample and reference material are enclosed in the single
furnace together.
6
Sensor
heater
2. Power compensation DSC
The specimen and reference temperatures are controlled independently
using separate ovens.
The energy difference is plotted as a function of sample temperature.
7

1. switch on
o nitrogen valve, DSC, cooling and desktop
2. Stabilize the apparatuses for 30 min
3. Sample preparation
oPut the sample and reference on heater
4. Start the run
5. Analyze the Data
Operational Procedure
10
Pans, aluminum alloy, platinum, stainless steel and
silver.
It can be open, pin-hole, covered or sealed
Its size of the sample should be 0.5mg to 100mg.
Small sample pans (0.1 mL).
Material should completely cover the bottom of
the pan .
Avoid overfilling (minimize thermal lag).
How can a Sample Prepared?
11
1. Temperature
2. Weight balance
12
How to Calibrate DSC?
What can DSC measure? :-
a. Glass transition temperature (Tg)
b. Crystallization temperature (Tc)
c. Melting temperature (Tm)
d. Polymers crystallinity determination
Interpretation of DSC data and analysis
13
a. The Glass Transition Temperature
Tg: amorphous material undergoes a transition from a brittle or hard state
to a rubber-like viscous state.
Peaks will show an sudden and linear decrease
14
Endothermic
Polymers will give off enough energy to move into very ordered arrangements, which is
called crystals. (exothermic)
Here there is latent heat of crystallization
15
b. Crystallization Temperature
Exothermic peak
Cooling after rubbery state
similar in size to the corresponding melting point
peaks.
Some differences may appear as a result of super
cooling but the peak area should not deviate by
more than 20%.
Crystallization Point Peak Examples
16
Heat
flow
endo
up(mW/m2)
As a solid sample melts to a liquid, it will require more heat flowing to
the sample to increase its temperature at the same rate as the reference.
17
c. Melting Temperature
Endothermic peak
heat flowing after crystalline

Putting it all together
d. Polymers Crystallinity Determination
Properties of polymers like comfort, strength and
absorbency are highly affected by percent
crystallinity.
Polymer Hm° (J/g)
Nylon 6 230.1
Nylon 6,6 255.8
PET 140.1
Polypropylene 207.1
Polyethylene 293.6
Polylactic acid 93.1
Reference value (The heat of melting if the
polymer were 100% crystalline).

DSC measures the energy required to keep both the reference and the
sample at the same temperature.
DSC an important tool in the experimental characterization of
polymeric materials.
DSC measures the heat capacity of a sample by recording the heat
flow rate into the sample and comparing it to a reference sample.
From the DSC curve one can determine materials transition points
like Tg, Tc and Tm.
It determine the degree of crystallinity for thermoplastic materials.

  • 18. As a solid sample melts to a liquid, it will require more heat flowing to the sample to increase its temperature at the same rate as the reference. 17 c. Melting Temperature Endothermic peak heat flowing after crystalline
  • 21. d. Polymers Crystallinity Determination Properties of polymers like comfort, strength and absorbency are highly affected by percent crystallinity.

  • 27. DSC measures the energy required to keep both the reference and the sample at the same temperature. DSC an important tool in the experimental characterization of polymeric materials. DSC measures the heat capacity of a sample by recording the heat flow rate into the sample and comparing it to a reference sample. From the DSC curve one can determine materials transition points like Tg, Tc and Tm. It determine the degree of crystallinity for thermoplastic materials. 26 Summary
