A

It often increases thermal conductivity due to distinct phase characteristics.

B

It has no significant impact on thermal conductivity.

C

It decreases thermal conductivity by creating a uniform structure.

D

It selectively enhances thermal conductivity only in specific temperature ranges.

Understanding the Answer

Let's break down why this is correct

When the blend separates, it forms distinct regions that can conduct heat better than a single phase. Other options are incorrect because This answer assumes nothing changes, but phase separation actually makes heat travel in more direct lanes; Separating the blend does not make it uniform; it creates separate areas.

Polymer morphology refers to the study of how polymers can be structured differently, affecting their properties. For example, polyethylene can exist in high density (HDPE) or low density (LDPE) forms, with different branching patterns impacting the plastic's flexibility and strength.
