Chapter 1 is general introduction of benzoxazine, electrochromism, and polymer memory. Chapter 2 includes a series of novel triarylamine (TPA)-based polybenzoxazines (PBs) which were prepared by the thermal-induced curing reaction of a series of novel PB precursors. Two diamines, 4,4''-diamino-4''-methoxytriphenylamine and N,N''-bis(4-aminophenyl)-N,N''-di(4-methoxyphenyl)-1,4-phenylenediamine, were used in this research, which were published by our group before. Chapter 3 includes the investigations of electrochromic and memory behaviors of novel PBs and PB precursors. Chapter 4 is conclusions. The synthesis, thermal properties, electrochemical properties, electrochromic properties, and memory behaviors of novel TPA-based PBs and PB precursors were investigated and compared. Comparing with the traditional PBs without TPA moieties, the novel TPA-based PBs exhibited more excellent thermal properties (Tg, 284-312 oC). In addition, the resulting TPA-based PBs and PB precursors containing bisphenol A (BPA) revealed interesting multi-electrochromic behavior with highly optical contrast both in visible and NIR region. Compared with their corresponding polyamides, these TPA-based PB precursors with BPA moiety not only showed lower oxidative potentials but also increased the oxidation stages due to the introduction of the TPA moieties. Besides, all the resulting polymer containing stronger electron-withdrawing group 4,4׳-sulfonyldiphenol (BPS) exhibited SRAM properties with longer retention time in terms of memory characteristics. To the best of our knowledge, this is the first time to explore and investigate the EC and memory behaviors of PB precursors and PBs with TPA moieties, and could be expected to open a new avenue of applications for PBs.ACKNOWLEGGEMENTS………………………………II ABSTRACT (in English) ……………III ABSTRACT (in Chinese) ………………IV TABLE OF CONTENTS………………………………V LIST OF TABLES………………………………………X LIST OF FIGURES…………………………………XI CHAPTER 1……………………………………………………1 CHAPTER 2…………………………………………………58 CHAPTER 3…………………………………………………81 CHAPTER 4………………………………………………113 APPENDIX…………………………………………………116 CHAPTER 1 General Introduction 1.1 BENZOXAZINE 2 1.1.1 Benzoxazine 2 1.1.2 Bifunctional Benzoxazine 3 1.1.3 Mechanism of Benzoxazine 4 1.1.4 Polybenzoxazine 5 1.1.5 Polybenzoxazine Precursor 7 1.2 INTRODUCTION OF ELECTROCHROMISM 10 1.2.1 Evolution of Electrochromism 10 1.2.2 Electrochromic Systems 13 1.2.2.1 Transition-metal Oxides 14 Tungsten Trioxide (WO3) 14 Iridium Oxide (IrO2) 15 1.2.2.2 Coordination Complexes 16 Prussian Blue (PB) 16 Phthalocyanines (Pc) 16 1.2.2.3 Organic Molecules 17 Viologens 17 1.2.2.4 Conducting Polymers 18 1.2.2.5 Arylamine-based Polymers 20 1.3 INTRODUCTION OF POLYMER MEMORY 25 1.3.1 General Concept 25 1.3.2 Types of Polymer Memory 26 1.3.3 Fundamentals and Device Architecture of Resistor-type Polymeric Memory 27 1.3.4 Mechanisms of Memory Devices 29 1.3.4.1 Filamentary Mechanism 29 1.3.4.2 Trapping-Detrapping Mechanism 31 1.3.4.3 Charge Transfer Mechanism 34 1.3.5 Evolution of Polymer Memory 37 1.3.5.1 Conjugated Polymers 37 1.3.5.2 Non-conjugated Polymers with Specific Pendent Groups 39 1.3.5.3 Polymer Composites 41 1.3.5.4 Functional High Performance Polymers 42 1.4 RESEARCH MOTIVATION 45 REFERENCES AND NOTES 48 CHAPTER 2 Flexible Polybenzoxazine Thermosets Containing Triphenylamine-based derivatives with high glass transition temperatures ABSTRACT OF CHAPTER 2 59 2.1 INTRODUCTION 60 2.2 EXPERIMENTAL SECTION 62 2.2.1 Materials 62 2.2.2 Synthesis of Polybenzoxazine Precursors 63 2.2.3 Preparation of Polybenzoxazine Thick Films 65 2.2.4 Measurements 66 2.3 RESULTS AND DISCUSSION 68 2.3.1 Synthesis of Polybenzoxazine Precursors 68 2.3.2 Basic Characterization 73 2.4 SUMMARY 78 REFERENCES AND NOTES 79 CHAPTER 3 Novel Triarylamine-based Polybenzoxazines and Polybenzoxazine Precursors for Multi-Colored Electrochromic and Memory Applications.
