Artificially Engineered Protein Polymers
Annual Review of Chemical and Biomolecular Engineering, 2017Co-Authors: Yun Jung Yang, Angela L Holmberg, Bradley D OlsenAbstract:Modern Polymer science increasingly requires precise control over macromolecular structure and properties for Engineering advanced materials and biomedical systems. The application of biological processes to design and synthesize artificial protein Polymers offers a means for furthering macromolecular tunability, enabling Polymers with dispersities of ∼1.0 and monomer-level sequence control. Taking inspiration from materials evolved in nature, scientists have created modular building blocks with simplified monomer sequences that replicate the function of natural systems. The corresponding protein Engineering toolbox has enabled the systematic development of complex functional Polymeric materials across areas as diverse as adhesives, responsive Polymers, and medical materials. This review discusses the natural proteins that have inspired the development of key building blocks for protein Polymer Engineering and the function of these elements in material design. The prospects and progress for scalable comme...

Artificially Engineered Protein Polymers
Annual Review of Chemical and Biomolecular Engineering, 2017Co-Authors: Yun Jung Yang, Angela L Holmberg, Bradley D OlsenAbstract:Modern Polymer science increasingly requires precise control over macro-molecular structure and properties for Engineering advanced materials and biomedical systems. The application of biological processes to de-sign and synthesize artificial protein Polymers offers a means for further-ing macromolecular tunability, enabling Polymers with dispersities of ∼1.0 and monomer-level sequence control. Taking inspiration from materials evolved in nature, scientists have created modular building blocks with sim-plified monomer sequences that replicate the function of natural systems. The corresponding protein Engineering toolbox has enabled the systematic development of complex functional Polymeric materials across areas as di-verse as adhesives, responsive Polymers, and medical materials. This review discusses the natural proteins that have inspired the development of key building blocks for protein Polymer Engineering and the function of these elements in material design. The prospects and progress for scalable com-mercialization of protein Polymers are reviewed, discussing both technology needs and opportunities.

Polymer Engineering based on reversible covalent chemistry a promising innovative pathway towards new materials and new functionalities
Progress in Polymer Science, 2018Co-Authors: Ze Ping Zhang, Min Zhi Rong, Ming Qiu ZhangAbstract:Abstract Reversible covalent Polymers are able to change their bond arrangement and structure via reversible reaction triggered by external stimuli including heating, light and pH, while retaining the stability of irreversible covalent Polymers in the absence of the stimuli. In recent years, more and more research has been devoted to utilization of reversible covalent bonds in synthesizing new materials, which not only overcomes disadvantages of permanent covalent Polymers, but also brings in new functionalities. More importantly, a series of novel techniques dedicated to Polymerized products with features such as properties regulation, self-healing, reprocessing, solid state recycling, and controllable degradation are developed, heralding the opportunity of upgrading of traditional Polymer Engineering. Although the exploration of this emerging topic is still in its infancy, the advances so far are encouraging and clearly directed to large scale applications. This review systematically outlines this promising trend, following a bottom-up strategy, taking into account both theoretical and experimental achievements. It mainly consists of four parts, involving design and preparation: (i) the basis of reversible covalent chemistry, (ii) rheology of reversible covalent Polymers, (iii) methods of construction of reversible covalent Polymers, and (iv) smart, adaptive properties offered by reversible covalent chemistry. The key elements for realizing reorganization of Polymers containing reversible covalent bonds are covered. The advantages and weaknesses of representative reaction systems are analyzed, while the challenges and opportunities to Engineering application of the equilibrium control based on reversible covalent chemistry for producing end-use Polymers are summarized. In this way, the readers may grasp both the overall situation as well as insight into future work.

molecular Engineering of conjugated Polymers for solar cells an updated report
Advanced Materials, 2017Co-Authors: Shengqiang Xiao, Qianqian ZhangAbstract:The device efficiency of Polymer:fullerene bulk heterojunction solar cells has recently surpassed 11%, as a result of synergistic efforts among chemists, physicists, and engineers. Since Polymers are unequivocally the “heart” of this emerging technology, their design and synthesis have consistently played the key role in the device efficiency enhancement. In this article, the first focus is a discussion on molecular Engineering (e.g., backbone, side chains, and substituents), then the discussion moves on to Polymer Engineering (e.g., molecular weight). Examples are primarily selected from the authors contributions; yet other significant discoveries/developments are also included to put the discussion in a broader context. Given that the synthesis, morphology, and device physics are inherently related in explaining the measured device output parameters (Jsc, Voc and FF), we will attempt to apply an integrated and comprehensive approach (synthesis, morphology, and device physics) to elucidate the fundamental, underlying principles that govern the device characteristics, in particular, in the context of disclosing structure-property correlations. Such correlations are crucial to the design and synthesis of next generation materials to further improve the device efficiency.
