The percentage crystallinity is represented by the image below. To calculate the percentage crystallinity, three essential parameters are needed and these parameters are Density of Amorphous Material (ρa), Density of Specimen (ρs) and Density of Perfect Crystalline Polymer (ρc).
The formula for calculating percentage crystallinity:
%C = 100(ρc(ρs – ρa)/ρs(ρc – ρa))
Where:
%C = Percentage Crystallinity
ρa = Density of Amorphous Material
ρs = Density of Specimen
And also, ρc = Density of Perfect Crystalline Polymer
Let’s solve an example;
Find the percentage crystallinity where the density of amorphous material is 12, the density of specimen is 10 and the density of perfect crystalline polymer is 4.
This implies that;
ρa = Density of Amorphous Material = 12
ρs = Density of Specimen = 10
And then, ρc = Density of Perfect Crystalline Polymer = 4
%C = 100(4(10 – 12)/10(4 – 12))
%C = 100(4(-2)/12(-8))
That is, %C = 100((-8)/(-80))
%C = 100(0.1)
%C = 10
Therefore, the percentage crystallinity is 10%.
