Agglomeration phenomenon in graphene/polymer nanocomposites: Reasons, roles, and remedies

Applied Physics Reviews, Год журнала: 2024, Номер 11(4)

Опубликована: Окт. 2, 2024

The addition of low-loading content nanofillers may improve the material properties polymer-based nanocomposites. This improvement directly corresponds to density well-dispersed in matrix. However, for higher nanofiller loadings, nanocomposites' not only be improved but also degraded due agglomeration. complex phenomenon, where tend form agglomerates with enhancement volume fraction, poses significant challenges materials science and nanotechnology. It has been proven that agglomerations hinder performance nanocomposites thwart unique most aspects. Graphene, one used nanofillers, plays a remarkable role Therefore, key focus current review is provide insight into impact agglomeration on various such as tensile, flexural, fracture, fatigue, thermal, electrical, barrier characteristics polymer reinforced by graphene-based structures. A comprehensive factors leading graphene was presented. concluded could developing nanocomposites, controlling were discussed depth, highlighting issue's complexity.

Three-Dimensional Printable Magnetic Hydrogels with Adjustable Stiffness and Adhesion for Magnetic Actuation and Magnetic Hyperthermia Applications

Gels, Год журнала: 2025, Номер 11(1), С. 67 - 67

Опубликована: Янв. 15, 2025

Stimuli-responsive hydrogels hold immense promise for biomedical applications, but conventional gelation processes often struggle to achieve the precision and complexity required advanced functionalities such as soft robotics, targeted drug delivery, tissue engineering. This study introduces a class of 3D-printable magnetic with tunable stiffness, adhesion, responsiveness, prepared through simple efficient “one-pot” method. approach enables precise control over hydrogel’s mechanical properties, an elastic modulus ranging from 43 kPa 277 kPa, tensile strength 93 421 toughness 243 kJ/m3 1400 kJ/m3, achieved by modulating concentrations acrylamide (AM) Fe3O4 nanoparticles. These exhibit rapid heating under alternating field, reaching 44.4 °C within 600 s at 15 wt%, demonstrating potential use in mild hyperthermia. Furthermore, integration nanoparticles nanoclay into AM precursor optimizes rheological properties ensures high printability, enabling fabrication complex, high-fidelity structures extrusion-based 3D printing. Compared existing hydrogels, our platform uniquely combines adjustable strong multifunctionality, offering enhanced capabilities actuation hyperthermia applications. advancement marks significant step toward scalable production next-generation intelligent medicine bioengineering.
