Special Issue Information

Dear Colleagues,

Crosslinked polymer networks possess an array of desirable properties, including elasticity, mechanical strength, and convenient processability. As a result, materials based on polymer networks are the backbone of many modern industries, including automotive, cosmetics, food, and packaging. Research efforts have been aimed at expanding the potential of polymer networks by introducing novel functionalities such as responsiveness to stimuli, self-healing, biocompatibility, toughness, and controlled swelling. Polymer networks possessing these advanced functionalities are envisioned to provide engineering solutions and to drive the progress in many cutting-edge areas such as aerospace, medicine, prosthetics, and soft robotics. This Special Issue aims to present recent progress in the synthesis, modification, application, and theoretical understanding of polymer networks with added functionality.

Tuning the Swelling Properties of Smart Multiresponsive Core-Shell Microgels by Copolymerization
Polymers 2019, 11(8), 1269; https://doi.org/10.3390/polym11081269 - 31 Jul 2019
Abstract
The present study focuses on the development of multiresponsive core-shell microgels and the manipulation of their swelling properties by copolymerization of different acrylamides—especially N-isopropylacrylamide (NIPAM), N-isopropylmethacrylamide (NIPMAM), and NNPAM—and acrylic acid. We use atomic force microscopy for the dry-state characterization of [...] Read more.
The present study focuses on the development of multiresponsive core-shell microgels and the manipulation of their swelling properties by copolymerization of different acrylamides—especially N-isopropylacrylamide (NIPAM), N-isopropylmethacrylamide (NIPMAM), and NNPAM—and acrylic acid. We use atomic force microscopy for the dry-state characterization of the microgel particles and photon correlation spectroscopy to investigate the swelling behavior at neutral (pH 7) and acidic (pH 4) conditions. A transition between an interpenetrating network structure for microgels with a pure poly-N,-n-propylacrylamide (PNNPAM) shell and a distinct core-shell morphology for microgels with a pure poly-N-isopropylmethacrylamide (PNIPMAM) shell is observable. The PNIPMAM molfraction of the shell also has an important influence on the particle rigidity because of the decreasing degree of interpenetration. Furthermore, the swelling behavior of the microgels is tunable by adjustment of the pH-value between a single-step volume phase transition and a linear swelling region at temperatures corresponding to the copolymer ratios of the shell. This flexibility makes the multiresponsive copolymer microgels interesting candidates for many applications, e.g., as membrane material with tunable permeability. Full article
