编者按：电致变色研究的复兴与快速增长

电致变色是一个典型的多学科交叉研究领域: 涉及有机与无机材料、物理与化学、电子与光学器件、测试控制及封装技术、太阳能辐射光谱调控与节能、显色与热控等诸多基础和应用研究。近年来, 电致变色研究呈现百花齐放、精彩纷呈的复兴态势, 特别是在中国的科研技术人员快速进入这一研究领域之后, 使得多年稍显沉寂的国际电致变色研究领域浮现出勃勃生机。这一形势大致从国际国内电致变色专业学术会议参会人员的规模数量上可见一斑。两年一度的国际电致变色会议(International Meeting on Electrochomism-IME)已经举办到第13届, 最近连续几届参会人数基本维持在150人左右。而国内两年一度的全国电致变色会议(Chinese Meeting on Electrochromism-CME), 参会人数由第1届的26人、第2届的150人、第3届的178人、快速增加到2019年第4届的352人。中国的学术界和产业界都对电致变色科学产生了浓厚的兴趣, 每次国内电致变色学术会议的参会人员大致维持在学术科研人员1/3、研究生1/3、企业界人员1/3的比例。

Rejuvenation and Rapid Growth on Electrochromism Researches

Electrochromism is a typical multidisciplinary crossing research field,involving organic and inorganic materials,physics and chemistry,electronics and optics,testing and controlling and packaging technologies,solar energy and radiation spectral modulation and energy conservation,color and thermal controlling,and many other basic and applied researches.In recent years,electrochromism researches exhibit a colorful and exciting revival trend,especially after many Chinese scientists and companies came into this field.It brings vitality into the international electrochromism research community,which has been a little tranquil for many years.This conclusion can be detected from comparison of the participants number in international and domestic professional academic electrochromic conferences.The bi-annually International Meeting on Electrochomism-IME has been held the 13th session until now,with the number of participants remaining around 150 in recent several times.But for the two-yearly Chinese Meeting on Electrochromism-CME,the number of participants has been quickly increasing from 26 at the 1st,150 at the 2nd,178 at the 3rd,to 352 at the 4th CME held in August 2019.Both Chinese academics and industries are deeply interested in electrochromism.The participants of each CME are composed of a third from academic researchers,a third from graduate students,and a third from industries.
