Abstract
Currently, there are no straightforward methods to 3D print materials with nanoscale control over morphological and functional properties. In this talk, a novel approach for the fabrication of materials with controlled nanoscale morphologies using a rapid and commercially available Digital Light Processing 3D printing technique will be presented. The approach uses a controlled/living radical polymerization technique, more specifically, reversible addition-fragmentation chain-transfer (RAFT) polymerization, to control the topologies of the polymers.[1-2] In this talk, we report a rapid visible light mediated polymerization process and applied it to a 3D printing system.[3] Following the optimization of the resin formulation, a variety of 3D printing conditions will be presented to prepare functional materials.[4] The mechanical properties of these 3D printed materials were investigated under different conditions, showing that the control of the polymer structure can affect the performance of these materials.[5] Furthermore, the polymer networks were able to be reactivated after the initial 3D printing process, which allowed the post functionalization of the printed materials via secondary photopolymerization processes, enabling to introduce information.[6] Finally, by controlling the polymer architecture, we were able to precisely control the nanostructure of these 3D printed materials via a polymerization induced microphase separation.[7] The effect of nanostructure on 3D printed material properties will be discussed as well as their potential applications in drug delivery and energy storage, such as their use as solid polymer electrolytes for supercapacitor application. Finally, we will discuss a new approach for the recovery of resin after 3D printing enabling us to recycle these 3D printed materials.

SELF-IMMOLATIVE POLYMERS: CHEMISTRY AND APPLICATIONS OF STIMULI-RESPONSIVE DEPOLYMERIZATION

Abstract
Degradable polymers are of growing interest for many areas, including biomedical applications, smart materials and devices, and to address the challenges associated with plastics pollution. Significant progress has been made using backbones such as polysaccharides, polyesters, and a growing number of bio-based polymers. However, in some cases it is desirable to be able to control precisely when and where polymers degrade and to access their degradation under a diverse range of conditions. Self-immolative polymers are a growing class of degradable polymers that undergo controlled end-to-end depolymerization following a stimulus-mediated backbone or end-cap cleavage (Figure 1) (1, 2). This presentation will describe the development of self-immolative polymers based on cyclization-elimination mechanisms (3, 4) and those which depolymerize due to their low ceiling temperatures (5). Advantages and disadvantages of different backbones will be discussed. In addition, the potential application of these polymers in applications such as nanopatterning, hydrogels, and self-assemblies that can encapsulate and release nucleic acids will be presented.

END-GROUP CHEMISTRY: PATHWAYS TO NETWORK MORPHOLOGIES AND SUPERIONIC POLYMERS

Abstract
End-group functionalization has become a powerful and versatile strategy in polymer science, allowing precise tuning of intrinsic polymer properties, such as thermal transitions, solubility, and crystallization, without altering the polymer backbone. In our group’s work, we have shown that end-group interactions can direct polymer self-assembly, enabling the formation of thermodynamically stable, highly frustrated three-dimensional network structures. I propose revising traditional block copolymer phase diagrams to incorporate end–end interactions and end-group arrangements. When end-functionalized block copolymers exhibit strong end–end associations, network phases such as gyroid, diamond, and primitive can occupy a significantly expanded phase window, replacing the lamellar structures typically expected. This underscores the powerful role of end-group chemistry in shaping functional nanomaterials. This concept also provides a pathway for developing superionic polymers by strategically designing charged end groups that finely tune molecular interactions. Such interactions decouple ion relaxation from polymer relaxation, overcoming the trade-off between ionic conductivity and mechanical strength seen in many solid-state polymer electrolytes. These insights highlight the transformative potential of end-group chemistry for next-generation polymer materials and provide a foundation for designing functional nanomaterials for emerging applications, including solid-state battery electrolytes, mechanical metamaterials, and optical metamaterials.
