摘要

在本工作中，以绿色策略开发了杂交生物基苯并恶嗪，用于形状记忆应用。以腰果酚和愈创木酚两种生物基材料为原料，采用无溶剂法制备腰果酚- jeffamine D230 （CJ）和双愈创木酚- furfuryamine （BGF）生物基苯并嗪单体。采用BGF-CJ - 100-0、80-20、60-40、40-60和0-100对不同重量百分比的BGF和CJ苯并恶嗪进行杂交，研究其热刺激响应特性。采用1H核磁共振（NMR）和傅里叶红外光谱（FTIR）对合成的苯并恶嗪进行了结构分析。采用热重分析（TGA）和差示扫描量热法（DSC）分析了聚苯并恶嗪的热性能。共聚物中P（BGF20-CJ80）的玻璃化转变温度较低，降解温度最高。同样，P共聚物（BGF60-CJ40）具有优异的形状记忆性能，连续分析表明，BGF60-CJ40的形状固形率为95 ~ 96%，形状恢复率为98 ~ 100%。这一优异的性能结果背后的原理与腰果酚- jeffamine D230苯并恶嗪中存在的刚性交联恶嗪环和长脂肪链的协同作用有关。目前的研究工作主要集中在生物基原料的利用和化石基双酚a的替代，以缓解环境问题。

Development of new bio-based shape memory hybrid polybenzoxazines through green strategy

In the present work, hybridized bio-based benzoxazines were developed with a green strategy for shape memory applications. Herein, two bio-based materials of cardanol and guaiacol were utilized to synthesize bio-based benzoxazine monomers of cardanol-Jeffamine D230 (CJ) and bis-guaiacol-furfurylamine (BGF) by using a solvent-free method. Different weight percentage ratios (wt %) of BGF and CJ benzoxazines were hybridized (BGF-CJ – 100–0, 80–20, 60–40, 40–60 and 0–100) and studied their thermal stimulus responsive properties. The structure of synthesized benzoxazine was analyzed using ¹H nuclear magnetic resonance (NMR) spectroscopy and Fourier transform infra-red (FTIR) spectroscopy. The thermal properties of polybenzoxazines were analyzed by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Among the co-polymers, P(BGF20-CJ80) shows the lower value of glass transition temperature with the highest degradation temperature. Similarly, the co-polymer of P(BGF60-CJ40) possess excellent shape memory properties and for consecutive analysis, the shape fixity ratio is 95 − 96 % for BGF60-CJ40, and its shape recovery ratio is 98–100 %. The principle behind this excellent performance results were related to the synergistic effects of rigid cross-linked oxazine rings and long aliphatic chain present in cardanol-Jeffamine D230 benzoxazine. The present research work is mainly focused on the utilization of bio-based raw materials, and the replacement of fossil-based bisphenol-A, with an objective of alleviation of environmental problems.

期刊介绍： European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas: Polymer synthesis and functionalization • Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers. Stimuli-responsive polymers • Including shape memory and self-healing polymers. Supramolecular polymers and self-assembly • Molecular recognition and higher order polymer structures. Renewable and sustainable polymers • Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites. Polymers at interfaces and surfaces • Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications. Biomedical applications and nanomedicine • Polymers for regenerative medicine, drug delivery molecular release and gene therapy The scope of European Polymer Journal no longer includes Polymer Physics.
