Keynote Report 2: Nanocarbon composites as wearable sensors and electronics
Abstract: This presentation reports the fabrication of interconnected graphene and nanocarbon materials to construct flexible composites as wearable sensors and electronics. Facile fabrication of highly flexible and sensitive sensors is essential for emerging applications such as wearable electronics. Carbon nanomaterials such as graphene, carbon nanotubes, carbon black and carbon nanofibers have been extensively explored as sensing elements to fabricate highly sensitive, stretchable, directionally-selective and stimulus-discriminating piezoresistive sensors. Interconnected, multi-dimensional architectures are prepared in different approaches, for example, graphene foam, graphene woven fabric and carbon nanotubes are grown on a metal template via chemical vapor deposition, while graphene aerogel is prepared by rational assembly of graphene oxide sheets into graphene hydrogel followed by directional freeze-drying. Another useful flexible nanocarbon structure is the highly-aligned carbon nanofibers prepared by electrospinning and carbonization of polymer precursor. The current state-of-the-art developments are discussed of flexible sensors made of 1D fibrous, 2D planar and 3D cellular architectures using simple, cost-effective and solution processable strategies for detecting physiological strains, tactile pressures and temperatures. The operational mechanisms along with existing applications of wearable sensors are presented. The challenges these sensors are currently facing and potential opportunities for novel applications are discussed to offer new insights into future potential in this field.

Keynote Report 2: Meso-nano scale experiments and simulations on hierarchical interfaces of composites
Abstract:Plant fibers possess the advantages of green environmental protection and rich sources. They have specific mechanical properties comparable to man-made fibers and are expected to become an important reinforcement of composites. The unique hierarchical structures affect the load transfer mode of plant fiber reinforced composites. To serve the task of interfacial design of plant fiber reinforced composites (PFRCs), it is necessary to quantify the hierarchical interfacial properties. Firstly, by applying the nanoindentation technology, the mechanical properties of multi-layer interface of PFRCs, including modulus, hardness, energy dissipation and ability of crack initiation and propagation, were measured from single-step and multi-step static nanoindentation methods. Subsequently, the fatigue characteristics of multiple interfaces in PFRCs under cyclic loading were evaluated with nanoscale dynamic mechanical analysis. Finally, combined with the finite element simulation in the meso-scale, the multi-stage failure behaviors of the hierarchical interfaces in composites were presented by introducing the multiple interface performance parameters obtained at the nano-scale. The results showed that the failure at the multi-layer interface of PFRCs caused by crack initiation and propagation appeared in sequence. The experimental results in nano-scale provide a support and basis for in-depth analysis of the interfacial properties and failure mechanisms of composites in meso-scale.
主题报告2：复合材料层次界面中纳米尺度实验与模拟
摘要：植物纤维具有绿色环保、来源丰富的优势，具有与人造纤维相当的特定力学性能，有望成为复合材料的重要增强材料。独特的分层结构影响植物纤维增强复合材料的载荷传递方式。为了服务于植物纤维增强复合材料(PFRC)的界面设计任务，有必要量化分级界面特性。首先，应用纳米压痕技术，采用单步法和多步法静态纳米压痕法测量了PFRCs多层界面的力学性能，包括模量、硬度、能量耗散及裂纹萌生和扩展能力。随后，通过纳米级动态力学分析评估了循环载荷下PFRC中多个界面的疲劳特性。最后，结合细观尺度的有限元模拟，通过引入在纳米尺度获得的多个界面性能参数，给出了复合材料中分层界面的多阶段失效行为。结果表明，PFRCs多层界面处由裂纹萌生和扩展引起的破坏依次出现。纳米尺度的实验结果为深入分析介观尺度复合材料的界面性能和失效机理提供了支持和依据。

Keynote Report3: Reversibly interlocked polymer networks
Abstract: Combining different polymers together to obtain multi-component polymer systems is an important and effective method to develop novel polymeric materials and to regulate their properties. However, the synergistic effect between different components can hardly play its full role because of the ubiquitous phase separation. To solve this problem, we developed a novel strategy to prepare multi-component polymer systems as follows, in which phase separation can be suppressed. Firstly, two covalent adaptive networks respectively containing orthogonal reversible covalent bonds were synthesized. Next, the two single networks were dissolved in a co-solvent under proper stimulus as a result of the reversible reactions of the included reversible bonds. Accordingly, the solutions with the fragments of the single networks can be well mixed, and the latter were allowed to be reconstructed together through topological rearrangement with the assistance of inter-component secondary interactions during removal of the stimulus and co-solvent. Eventually, co-networks with relative independence, i.e. reversibly interlocked polymer networks, were obtained. Owing to the forced miscibility effect induced by the interlocked structure, even immiscible polymer pairs can be homogeneously interlaced with each other. In this context, there would be more freedom to choose the raw materials, and versatile multi-component polymer systems with high performance and novel functionalities can be developed. The presentation introduces the material design and general preparation method of reversibly interlocked polymer networks. Afterwards, the structural features of the interlocked polymer networks, and a few applications of this type of material are discussed.
主题报告3：聚合物可逆互锁网络
摘要：将不同聚合物混合制备多组分聚合物复合体系是聚合物材料开发的重要手段，但是普遍存在的相分离现象使得不同组分间协同作用未能充分体现，因此发展能够充分抑制相分离的多组分聚合物复合体系制备新技术有着重要意义。利用动态交联聚合物网络拓扑结构的可逆变换，可以使不同交联聚合物网络间的分子链扩散与混合成为可能，待混合完全后再通过动态可逆共价键闭合来重筑交联网络，最终得到由不同子网络穿插互锁形成的均匀复合交联网络，即聚合物可逆互锁网络，其中的子网络之间没有共价键连接，具有相对的独立性。本报告由聚合物可逆互锁网络的设计制备出发，阐述了相关方法的概念、原理和所得材料的结构特点，介绍了基于聚合物可逆互锁网络策略的聚合物材料高性能化与功能化应用实例，同时分析了与聚合物互穿网络（IPNs）的区别，最后对这类材料未来可能的发展进行了分析和展望。
