The utilization of wood-derived building blocks (xylochemicals) and other abundantly available, non-food biomasses to replace fossil-based precursors is an attractive research subject in modern polymer science and engineering. The continuing development of economically viable bio-based feedstocks and subsequent, new platform chemicals opens opportunities to increase the resource base from which chemical and materials engineers can draw to meet specific polymer and composite property requirements. Recently, significant efforts have transpired to obtain bio-based polymers and composites with enhanced thermomechanical properties for a wide variety of applications, from adhesives to coatings to under-the-hood, lightweight, yet geometrically complex vehicle components. In continuing these efforts, we have prepared and examined a variety of bio-based thermoplastics, thermosets, and composites, including epoxies, vinyl esters, (meth)acrylates, allyl ethers, polyesters, and polycarbonates with and without reinforcing fibers. These novel materials were strategically assembled from monomers based on lignin-derived, (hemi)cellulose-derived, soy-derived, and cashew nut shell liquid-derived platform chemicals. This seminar will highlight our work on fundamentally understanding the processing-structure-property relationships of these bio-based polymers and composites via thermal, mechanical, and modelling techniques. Additionally, their utilities in military and civilian applications will be discussed along with an identification of critical technological gaps that should be investigated through advanced experimental techniques.
Joseph Stanzione, III received his M.S./B.S. in Chemical Engineering at Drexel University and his Ph.D. in Chemical Engineering at the University of Delaware under the directions of Professor Giuseppe Palmese and Professor Richard Wool, respectively. He then joined the chemical engineering faculty of Rowan University in 2013, where he is an associate professor and is the founding director of Rowan’s Advanced Materials & Manufacturing Institute (AMMI). His research program focuses on advancing fundamental and applied science and engineering technology related to materials research with the goal to sustainably utilize nature’s chemistries to enhance material performance. His specific research interests include: the utilization of lignocellulosics as an alternative renewable chemicals feedstock; green chemistry and engineering for the development of next-generation lignocellulosic biorefineries; bio-based polymers and composites for high-performance and energy applications; and advancing the technological disruptiveness of additive manufacturing (AM), including cold spray AM. His work has resulted in various patents and publications, including a front cover highlighted article in ChemSusChem. He is a co-recipient of U.S. EPA’s Presidential Green Chemistry Challenge Award in 2013, the recipient of the 2016 AIChE Delaware Valley Chapter Outstanding Faculty of the Year Award, Rowan University’s 2020 Faculty Research Achievement Award, and co-editor of the Special Issue: Sustainable Polymers and Polymer Science: Dedicated to the Life and Work of Richard P. Wool published by the Journal of Applied Polymer Science in 2016.
