Special Issue Information

Dear Colleagues,

Polymers are typically flexible and malleable solids with tuneable mechanical features and processability. When they combine with inorganic components to afford polymer hybrid materials endowing them specific functionalities and/or reinforce the mechanical and thermal properties. The polymer hybrid materials not only combine the features of the starting components, but also encompass enhanced unique properties result from synergetic effects, which eventually overcomes the structural and functional limits of the conventional materials. The polymer hybrid materials of monolith and coating/film with porous, layered or core-shell hierarchical structures and interpenetrating networks can be synthesized through sol-gel method, polymerization reaction and self-assembly process, etc. Their properties can be tailored by combination of polymers and functional/additive components such as luminescent/magnetic moieties, carbonaceous materials, biological substances, inorganic fibres/clays, metal-organic frameworks, polyhedral oligomeric silsesquioxanes, polyoxometalates and metal oxide particles. The structural and functional versatilities of the polymer hybrid materials accounts for their diverse applications in the fields ranging from optoelectronics, dielectric, photovoltaics, waveguide, sensor, gas adsorption/separation, catalysis, flame/fire retardancy, drug delivery and biomedical engineering.

The scope of this Special Issue is to cover all the aspects related to the polymer hybrid materials. Authors are welcome to submit the latest research works on this topic in the form of original research or review articles.

Hybrid joints of metal- and fiber-reinforced-polymer offer great potential for lightweight applications. Thereby, a fast and reliable joining process is mandatory for mass-production applications. To this end, this study assesses inductive spot-joining in combination with prior thermal spray coating of the metal adherent. A nickel–aluminum 95/5 coating was applied to achieve high adhesion through mechanical interlocking and to act as susceptor for the inductive joining process. The joint strength was assessed with lap shear specimens consisting of EN AW-6082 aluminum alloy and glass fiber reinforced polyamide 6 or polypropylene, respectively. The joints were further investigated in terms of heating time and hygrothermal cyclic loading. The results showed that significant time savings for the joining process as well as strong adhesion were achieved due to the coating. Moreover, the high strengths were even preserved under hygrothermal cyclic loading. Full article

Polymer-based tri-layered (bone, intermediate and top layers) scaffolds used for the restoration of articular cartilage were prepared and characterized in this study to emulate the concentration gradient of cartilage. The scaffolds were physically or chemically crosslinked. In order to obtain adequate scaffolds for the intended application, the impact of the type of calcium phosphate used in the bone layer, the polymer used in the intermediate layer and the interlayer crosslinking process were analyzed. The correlation among SEM micrographs, physical-chemical characterization, swelling behavior, rheological measurements and cell studies were examined. Storage moduli at 1 Hz were 0.3–1.7 kPa for physically crosslinked scaffolds, and 4–5 kPa (EDC/NHS system) and 15–20 kPa (glutaraldehyde) for chemically crosslinked scaffolds. Intrinsic viscoelasticity and poroelasticity were considered in discussing the physical mechanism dominating in different time/frequency scales. Cell evaluation showed that all samples are available as alternatives to repair and/or substitute cartilage in articular osteoarthritis. Full article
