Polymerization-induced self-assembly of liquid crystalline ABC triblock copolymers with long solvophilic chains

Huo, Meng; Wan, Zhengyi; Zeng, Min; Wei, Yen; Yuan, Jinying

Understanding the self-assembly of liquid crystalline (LC) block copolymers is challenging because of the complex influencing factors. In this article, we studied the influence of the solvophilic chain length on the self-assembly of the LC ABC triblock copolymer poly(N,N-dimethylaminoethyl methacrylate)-b-poly(benzyl methacrylate)-b-poly…

Direct formation of form I’ crystals in polybutene-1/polypropylene blend enhanced by cold crystallization

Zhong, Zhenxing; Ge, Huan; Su, Zhaohui

During commercial processing of isotactic polybutene-1 (PB-1), crystallization kinetics favor form II while thermodynamics favor the more desired form I/I′, and once the former is adopted, transformation to the latter is extremely slow. In this work, the cold crystallization behavior of PB-1/iPP (isotactic polypropylene) blend (90/10) is investigated with emphasis…

Uniaxial and Mixed Orientations of Poly(ethylene oxide) in Nanoporous Alumina Studied by X-ray Pole Figure Analysis

Su, Cui; Shi, Guangyu; Li, Xiaolu; Zhang, Xiuqin; Müller, Alejandro J.; Wang, Dujin; Liu, Guoming

The orientation of polymers under confinement is a basic, yet not fully understood phenomenon. In this work, the texture of poly(ethylene oxide) (PEO) infiltrated in nanoporous anodic alumina oxide (AAO) templates was investigated by X-ray pole figures. The influence of geometry and crystallization conditions, such as pore diameter, aspect ratio,…

Spontaneous Structural Transition in Phospholipid-Inspired Aromatic Phosphopeptide Nanostructures

Pellach, Michal; Atsmon-Raz, Yoav; Simonovsky, Eyal; Gottlieb, Hugo; Jacoby, Guy; Beck, Roy; Adler-Abramovich, Lihi; Miller, Yifat; Gazit, Ehud

Phospholipid membranes could be considered a prime example of the ability of nature to produce complex yet ordered structures, by spontaneous and efficient self-assembly. Inspired by the unique properties and architecture of phospholipids, we designed simple amphiphilic decapeptides, intended to fold in the center of the peptide sequence, with a…

Thermal-Induced Denaturation and Aggregation Behavior of Lysozyme and Bovine Serum Albumin: a Thermodynamic and Structural Study

Perez, Aline Sanches; Oliveira, Cristiano Luis Pinto

Solution studies permit a direct investigation of the particles on a well-defined environment. Fluorescence, circular dichroism, scattering, and calorimetry provide, individually, very important information among the protein structure, overall shape, and thermodynamic equilibrium. In this work, a combination of these techniques is presented for the study of denaturation induced by…

Factors controlling the structure of syndiotactic polystyrene upon the guest exchange and guest extraction processes

Shaiju, P.; Bhoje Gowd, E.

The role of host preparation method on the structural phase transition of syndiotactic polystyrene (sPS) after the guest exchange process has been thoroughly investigated in our previous study using a series of n-alkanes . In addition to the host preparation method, we have found that guest molecules used for the…

Oxidation reactions in kink banded regions of UHMMPE fiber-based laminates used in body armor: A mechanistic study

Tsinas, Zois; Forster, Amanda L.; Al-Sheikhly, Mohamad

This work demonstrates the synergy between the thermo-mechanical and humidity induced degradation as well as the oxidation reactions in the kink-banded areas of ultra-high molar mass polyethylene (UHMMPE) fiber-based laminates used in body armor. For aged materials, the energy-dispersive X-ray spectroscopy (EDS) and Fourier transform infrared spectroscopy (FTIR) results reveal…
