- Semidilute solution structure of cellulose in an ionic liquid and its mixture with a polar organic co-solvent studied by small-angle X-ray scattering

Cellulose is the most abundant biopolymer on earth, and new methods to dissolve it have garnered much interest. Solutions of cellulose in ionic-liquid and its mixture with a polar organic co-solvent are studied by small-angle X-ray scattering (SAXS) to evaluate the structure and thermodynamic solution properties. Till now, these were only evaluated by rheological measurements. The results provide direct evidence of molecular dissolution of the cellulose chains and show good solvent conditions.

A water thread can split into several separated water drops due to the Rayleigh instability. The similar mechanism can result in the pearl-necklace conformation of polyelectrolytes. In this paper, the DNA pearl-necklace structures including a new rods-on-a-string structure were shown by morphology characterization. A complete experimental picture on the structure was presented, which helps to understand the collapse behavior of polyelectrolytes in poor solvents.
- Enhanced dielectric properties of polymer composite films induced by encapsulated MWCNTs with a one core-two shell structure
Shuangmin Yu and Gengchao Wang
Version of Record online: 25 MAR 2017 | DOI: 10.1002/polb.24341
The one core- two shell structured aMWCNTs@PANI-PSS nanofiber has been fabricated and its PVDF-HFP based composite film shows a high dielectric constant and relatively low dielectric loss. The approach in this study may be extended to the fabrication of similar hybrid composites with excellent mechanical and dielectric performance, which can be beneficial for applications in electronic devices.

Plasmon is an important strategy to enhance light harvesting efficiency in photovoltaic devices. However, the underlining mechanisms still need more solid photophysical support. This work uses various spectroscopic methods to investigate how particle plasmons influence the evolution dynamics of long-lived charges in polymer blends. It was revealed that the long-lived charges mainly resulted from the localization by particle plasmons. The morphology modification in the blend film made negligible contributions to this influence.
- A comparative study of calorimetric methods to determine the crosslinking degree of the ethylene-Co-vinyl acetate polymer used as a photovoltaic encapsulant

EVA copolymer foils used as encapsulants for photovoltaic (PV) cells need to be crosslinked during module manufacturing. Accurate and reliable methods are crucial for the determination of their crosslinking degree. The main purpose of this work is to reveal the chemical and physical fundamentals on which two calorimetric methods used to determine the crosslinking degree of EVA are based. For one of these methods based upon crystallization, the authors have revealed the crystallite size distribution of the copolymer and the influence the degree of crosslinking has upon it.
