What is it about?
This study explores the structure and behavior of polyethylene furanoate (PEF), focusing on the differences between its crystalline and amorphous forms. By examining the chain conformation and dynamics, we provide insights into how these properties affect PEF's overall performance. Understanding these aspects is crucial for improving PEF’s applications in sustainable packaging and other materials.

Why is it important?
This research is important because it provides a detailed understanding of polyethylene furanoate (PEF), a promising bio-based plastic, by detecting C-H...O hydrogen bonds that play a key role in its structure and properties. Using vibrational spectroscopy and quantum chemistry calculations, the study reveals how these bonds influence the chain conformation and dynamics in both crystalline and amorphous regions of PEF.
Perspectives
When we first embarked on studying polyethylene furanoate (PEF), we didn't anticipate the significant role that C-H...O hydrogen bonds would play in its structure. Discovering these bonds was a turning point, revealing how they profoundly impact the chain conformation and dynamics of PEF in both its crystalline and amorphous forms. The use of vibrational spectroscopy and quantum chemistry calculations allowed us to uncover these hidden interactions, which are now being recognized as crucial for understanding and improving the properties of bio-based plastics. This discovery was both surprising and exciting, opening new avenues in the field and demonstrating the power of combining experimental and computational approaches.
