Polymer-Based Composites for Electromagnetic Shielding Application
Traditional metals and alloys are often used for electromagnetic interference (EMI) shielding due to their excellent electrical conductivity. However, they have drawbacks such as being heavy, expensive, and having low corrosion resistance, which limits their application in electromagnetic shielding. Therefore, it is crucial to develop novel EMI shielding materials. Polymers, being highly flexible, corrosion-resistant, and possessing high specific strength, are frequently employed in electromagnetic shielding materials.

Polymer Single-Crystal Functionalization Applications
Polymer physics has evolved significantly over the past century, transitioning from the early recognition of the chain structure of polymers to a mature field integrating principles from statistical mechanics, thermodynamics, and condensed matter physics. As an important part of polymer physics, polymer single crystals are crucial for understanding molecular structures and behaviors, enhancing material properties, and enabling precise functionalization. They offer insights into polymer crystallization kinetics, serve as templates for nanofabrication, and have applications in electronics, sensors, and biomedical fields.

Polymer Electrolyte Membranes Fuel Cell
The development of sulfonated hydrocarbon polymer (SHP)-based polymer electrolyte membranes (PEMs) has been pursued in order to overcome drawbacks of the perfluorosulfonic acid ionomer-based PEMs in fuel cell applications. To improve the proton conductivity of SHP-based PEMs without deterioration in physicochemical stability, control of polymeric architecture is necessary to form distinct phase-separated structures between the hydrophilic and hydrophobic domains. By pursuing rational design strategies for the copolymer architectures, it will be possible to develop high-performance SHP-based PEMs in fuel cell applications. This study focused on the synthetic procedures which underlie structure-engineered copolymers and their PEM properties.

Polymer 3D Printing
Polymer 3D printing is an emerging technology with recent research translating towards increased use in diverse industries. The polymer 3D printing process works by depositing a polymer in a directed fashion to form a completed part, generally through layer by layer deposition.  Polymer printing is advantageous because it enables printing low-cost functional parts with diverse properties and capabilities. An important aspect polymer 3D printing is the consideration of materials, processes, and design strategies that all influence a parts performance. Research in materials has led to the development of polymers with advantageous characteristics for mechanics and biocompatibility, with tuning of mechanical properties achieved by altering printing process parameters. Suitable polymer printing processes include extrusion, resin, and powder 3D printing, which enable directed material deposition for the design of advantageous and customized architectures.  Through careful consideration of material, process, and design it is possible to create a 3D printed polymer part of complex geometry that is tuned for a specific application on a per-print basis.
