Special Issue Information

Dear Colleagues,

At present, functional polymer composites are increasingly promising materials in materials science and engineering. Polymer composites, including nanocomposites, are made by the incorporation of fillers in polymer matrices, and offer many advantages. The properties of polymer composites are further improved by the surface modification of fillers or the matrix phase. Currently, there is an increasing demand for smart materials based on eco-friendly polymers for a wide variety of applications. Therefore, functional polymer composites are essential to the development of new technologies.

This Special Issue, “Functional Polymeric Composites: Synthesis, Characterization and Application II”, will be focused on the innovative original research and reviews in the field of functional polymer composites. Examples of acceptable research topics include: (a) surface modification, (b) smart biomaterials, (c) hybrid composites, (d) mechanical properties, (e) carbon, (f) textile materials, and (g) other functional polymer composites.

Nanohydrogel particles of polyethylene glycol (PEG), gelatin (GEL), and PEG–GEL mixtures (MIXs) were synthesized with a high electron beam and 60Co gamma-ray radiation. The relatively novel technique of Asymmetrical Flow Field Flow Fractionation (AF4 or AFFFF) coupled to a Multi-Angle Laser Light Scattering (MALLS) detector was mainly used to determine the hydrodynamic diameter (Dh) of the radiation-synthesized PEG, GEL, and PEG–GEL nanohydrogel particles. Our approach to achieving nanohydrogel particles is to enhance the intracrosslinking reactions and decrease the intercrosslinking reactions of the C-centered radicals of the PEG and GEL. The intracrosslinking reactions of these free radicals were enhanced via irradiation at temperatures of 77–80 °C and using a high dose rate and pulsed irradiation. The shorter average distance between the C-centered free radicals on the backbone of the thermally collapsed PEG and GEL chain, due to the destruction of hydrogen bonds, enhances the intracrosslinking reactions. It was observed that increasing the dose and dose rate decreased the Dh. DLS results lined up with AF4 measurements. This study provides researchers with a clean method to produce GEL–PEG hydrogels without the use of toxic reagents. Particle size can be tuned with dose, dose rate, and temperature as demonstrated in this work. This is ideal for medical applications as the use of ionizing radiation eliminates toxicity concerns and provides simultaneous sterilization of the material. Full article
