Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Fiber morphology and structure are characterized using various analytical tools that probe atomic, molecular, or thermal properties.
Step 1: Analyzing XRD and TEM.
X-ray diffraction (XRD) is the gold standard for measuring atomic order, specifically Crystallinity and crystallite size (II). TEM uses electrons to see *through* samples, revealing their Internal structure (IV) at extremely high resolution.
Step 2: Analyzing DSC and Birefringence.
DSC measures heat flow to find thermal Transitions (I) like Tg and Tm. Birefringence measures the total refractive index difference, which indicates Total orientation (III) of both crystalline and amorphous regions.
Step 3: Final Matching.
The correct sequence is: A-II, B-IV, C-I, D-III.
