Interfacial structure and properties of isotactic polybutene-1/polyethylene blends
e-Polymers, 2022 Polymer blending is one of the most economical and effective techniques for achieving products with high comprehensive performances. However, the immiscibility between polymers results in a weak interface, which is typically the position where material ...

Electrochemistry meets polymer physics: polymerized ionic liquids on an electrified electrode [PDF]
, 2021 Polymeric ionic liquids are emerging polyelectrolyte materials for modern electrochemical applications. In this paper, we propose a self-consistent field theory of the polymeric ionic liquid on a charged conductive electrode. Taking into account the conformation entropy of rather long polymerized cations within the Lifshitz theory and electrostatic and

Bouncing scalar field cosmology in the polymeric minisuperspace picture [PDF]
Mod. Phys. Lett. A 29 (2014) 1450169, 2014 We study a cosmological setup consisting of a FRW metric as the background geometry with a massless scalar field in the framework of classical polymerization of a given dynamical system. To do this, we first introduce the polymeric representation of the quantum operators. We then extend the corresponding process to reach a transformation which maps any
