Description :
Requisition Id 4122 Overview We are seeking a Postdoctoral Research Associate who will focus on polymer chemistry for binder jet additive manufacturing, and synthesis and characterization of carbon-fiber reinforced polymers. This position resides in the Soft Matter Group in the Chemical Sciences Division (CSD), Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL). The research will be focused on tailoring polymer chemistry for binder jet additive manufacturing (binder jetting), and developing novel carbon-fiber reinforced polymers. The binder jetting project aims to develop novel polymer binders, and the polymer composite project focuses on synthesis of new type of resins and functionalization of carbon fibers to enable mechanically robust yet rapidly processed carbon-fiber reinforced polymers. The projects tasks are synthesis of novel polymers using various polymerization/functionalization techniques and rigorous characterizations, such as DMA, tensile, rheology, NMR, surface tension, TGA, FTIR, SEC, and DSC. This research will be complemented by collaborations and interactions with other polymer scientists and mechanical engineers. The candidate is also expected to be involved with other projects including synthesis and characterization of dynamic polymers (e.g. vitrimers and self-healing polymers), polymer membranes for gas separation, and polymer electrolytes for energy storage including membrane development for fuel cell and flow battery. Major Duties/Responsibilities – Develop a formulation for 3D printing of novel polymers and composites with understanding its processability. – Characterization of polymers by standard methods including SEC, NMR, FTIR, TGA, DSC, DMA, tensile, rheology etc. – Conduct a binder jet 3D printing with novel binders. – Study the structure-property relationships of 3D-printed objects for mechanical properties, and its chemistry. – Design, synthesis, and characterization of well-defined polymers using various polymerization techniques including controlled polymerization methods (anionic, cationic, ATRP, RAFT, NMP, ROMP) and other methods (conventional free radical, step growth) – Synthesis and characterization of novel monomers and post functionalization of polymers – Functionalization of carbon fibers and fabrication of the composites – Investigate the processability of carbon-fiber reinforced polymers – Establish the relationships between the structure, mechanical properties and processability – Responsible for presenting and reporting research results and publishing scientific results in peer-reviewed journals in a timely manner – Ensure compliance with environment, safety, health and quality program requirements – Maintain strong commitment to the implementation and perpetuation of values and ethics Basic Qualifications – Ph.D. in Polymer Science and Engineering, Polymer Chemistry, Organic Chemistry, Chemical Engineering, Materials Science and Engineering or a closely related field completed in the last 5 years – Expertise in polymer synthesis and characterization methods Preferred Qualifications – Knowledge and expertise in synthesis of well-defined polymers and controlled functionalization including dynamic functional groups – Knowledge and expertise in mechanical and viscoelastic characterization of polymers, composites and polymer solutions – Knowledge and expertise in polymer processing and manufacturing – Knowledge and expertise in additive manufacturing – Self-motivated, with the ability to work independently, safety conscious, and participate creatively in refining projects directions – An excellent record of productive and creative research demonstrated by publications in peer-reviewed journals – Excellent oral and written communication skills, and the ability to work collaboratively in a team environment and interact effectively with a broad range of colleagues – Participate creatively in solving problems and refining projects directions – Work collaboratively in a team environment and interact effectively with a broad range of colleagues – An excellent record of productive and creative research demonstrated by publications in peer-reviewed journals – Excellent oral and written communication skills Special Requirements Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment.
