The Chemical Record, 2001 AbstractMolecular level studies of the structure and mechanical properties of polymer surfaces have been carried out by sum frequency generation (SFG) surface vibrational spectroscopy and atomic force microscopy (AFM). The surfaces of different grades of polyethylene and polypropylene have been characterized—including during the glass transition and ...

Mechanochemically accessing a challenging-to-synthesize depolymerizable polymer
Nature Communications, 2023 Polymers with low ceiling temperatures (Tc) are highly desirable as they can depolymerize under mild conditions, but they typically suffer from demanding synthetic conditions and poor stability.

Polymer Science: The Next Generation [PDF]
Macromolecular Rapid Communications, 2012 Shiyong Liu The three of us have to confess we felt a bit over-age when the editors of the Macromolecular Journals approached us for editing a young investigators issue for Macromolecular Rapid Communications . Although we would prefer not to think about it, this forced us to admit that we are slowly reaching the senior scientist category (i.e., the ...
