Why so charming the science is? I think this question always lingers in our mind.
When I was a child, I remember the best day maybe the day I got a box of crayons from my parents, I used them to draw a bird, a cloud, and my happy family. Over time, I became a master student at Peking University (China), and my major research field is organic materials synthesis and application.
Luckily, this summer I became a summer student of HZB, have to say, I really enjoy the life here, so I decided to make an electrochromic graffito as a gift for HZB. As you can see in the picture and video, I wrote the letter “H“ “Z“ “B“ on the ITO glass using three kinds of electrochromic materials that I synthesized. It’s just like using crayons to draw a picture on my childhood, but the biggest difference is that the color of the letter ‘ HZB ‘ can be changed under different potentials! Actually, this phenomenon is defined as electrochromism, the color change is caused by the redox process happened inside of the electrochromic polymers under the different potential bias. This is really an interesting research area, and I’ve made a lot of efforts to synthesize electrochromic polymers with several different colors. I think it is a fulfilling thing to draw a picture using the materials you synthesized.
From crayons to electrochromic materials, I think that’s the answer to why science is so charming. For me, when I was a kid, I liked to play with crayons, and fortunately, when I become a young scientist, I still like to play “science” and I believe that for every scientist, their research field was also full of interesting or meaningful things. Precisely, owing to the deep love of science, we can go further in our research field.
