The advancement of material technology actively facilitates modern technology development in fields like electronics, construction and transportation, as the latter very often requires the presence of materials with specific properties so as to meet specific applications. For example, the development of high performance computing and high-speed network would not have been possible if without the invention of low transmission loss materials. For the design, synthesis and application of these kinds of advanced materials, knowledge about various scientific spheres is essential. Amongst all the spheres, chemistry plays a significantly important role.

Structural materials and electronic materials


Structural materials are materials that primarily emphasize mechanical properties. They serve to withstand a force, and/or to provide support and are widely used in every aspect of life. In addition to sheer mechanical strength, researchers are trying to produce multifunctional materials, for example, self-healing concrete.

Meanwhile, stepping into the era of electronics, the urge for more advanced and sophisticated electronic materials is intensifying. For instance, to build more efficient electronic devices while minimizing the sizes, semiconductors of better performance are necessary. Apart from that, superconductors, molecular electronic devices, and light-responsive materials are some hot topics in the field.

Supramolecular polymers are a unique class of polymers that are held together by non-covalent interactions. Unlike traditional covalent polymers, supramolecular polymers can be easily disassembled and reassembled.


These materials have potential applications in smart materials with controllable functions. For example, light-driven soft actuators and light-triggered electronic devices. When exposed to light signals, those materials may change in structure, dipole, and chirality, and result in re-self-assembly.

Graphene as a C-reactive protein (CRP) sensor    link   video

C-reactive protein has a low concentration in human blood such that it is difficult to be monitored. Graphene with a large surface area and small pores that encapsulate redox molecules is used as a sensor. When gold nanoparticles bind to CRP pass through the graphene sensor via sweating. They bind to graphene molecules. Such binding causes the redox reaction that generates an electric current and is detected by the electronic component in the sensor.

Hence, energy conversion efficiency has risen thanks to the application of fullerene.

Bio-inspired, bio-mimic, and bio-based materials


Nature always offers scientists role models and ideas on developing new materials because naturally occurring biochemical systems are elegantly “designed” and exhibit superior performances in terms of physical properties and catalytic activities. Therefore, chemists are seeking ways to artificially replicate, at least part of, these complex biochemical systems by synthetic means. Furthermore, starting from naturally occurring materials, especially those usually considered as waste, is particularly attractive in terms of cost, safety, and sustainability.
