Polyacrylamide/carbon nanodot nanocomposite hydrogels with excellent mechanical properties are successfully prepared by free radical polymerization using carbon nanodots as cross-linkers.
- Monomers for Adhesive Polymers, 16 Synthesis of Acidic Dimethacrylates Starting from Thioglycerol

Article first published online: 26 MAY 2015 | DOI: 10.1002/mame.201500118
The novel acidic dimethacrylates 4a–c, 6, 11, and 16 were prepared. Their free radical homopolymerization, photopolymerization behaviors, and adhesive properties were investigated. Adhesives based on these acidic monomers were able to mediate a strong bond between the dental hard tissues (dentin and enamel) and a restorative composite. The adhesive containing the bisphosphonic acid 11 led to the highest dentin shear bond strength.
- Influence of Poly(ethylene oxide) (PEO) Percent and Lignin Type on the Properties of Lignin/PEO Blend Filament

The HWKL/PEO blend filament fabricated by melt spinning with the PEO percent of 15% has very uniform diameter and smooth surface, adequate compression, and tensile strength, and has thermally stable at a heating rate of 30 °C h−1. It may be the desirable composition used in FDM to manufacture 3D carbon-based nanostructure electrodes for high-performance supercapacitors.
- Influence of External Tension on the Structure and Properties of Melt-Spun PAN Precursor Fibers during Thermal Oxidation

During stabilization stage, the structure and properties of melt-spun PAN precursor fibers undergo a series physical and chemical changes formed infusible ladder structure. External tension mainly influenced on the chemical and crystal structures, carbon yield and physical properties. When external tension was 0.56 cN · dtex−1, pre-oxidized melt-spun fibers had excellently comprehensive properties.
- Shear-Induced Reinforcement Effect in Polymer/Fumed Silica Nanocomposites
Xun Chen and Margaret J. Sobkowicz
Article first published online: 21 MAY 2015 | DOI: 10.1002/mame.201500082
The work describes unusual network formation in nancomposites with fractal nanofillers under steady shear. Our results show that this shear-induced structure persists for long times after shearing event. This could have important implications for processing nanocomposites with improved mechanical properties.
