Modelling viscoelastic materials whose storage modulus is constant with frequency
International Journal of Solids and Structures, 2006 AbstractThis paper presents a relaxation function characterising viscoelastic materials whose storage modulus is constant with frequency, and whose loss factor shows the representative peak of damping materials. This behaviour is typical of some composite materials, where the elastic constituents give the constant modulus, and the polymeric components ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications
FEBS Open Bio, EarlyView.This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Poly(ether-ketone)/Silica Nanocomposites: Storage Modulus and Hardness
High Performance PolymersAbstract Dynamic mechanical properties of the poly(ether-ketone) (PEK) based nanocomposites reinforced with 0–30 wt.% (0-20.2 vol.%) SiO2 nanoparticles (20–40 nm) were investigated at 1 Hz over the temperature range of 30–250°C for the application in printed circuit boards/electronic substrates.
