Research progress and industrialization analysis of smart dimming technology
摘要
Abstract
Amid growing demands for energy efficiency optimization and intelligent light regulation,the development of smart dimming technologies featuring high response speed,low energy consumption,and scalable manufacturing integration is imperative.Recent advancements in electrochromic(EC),responsive liquid crystals,and nanomaterial-mediated dimming systems have accelerated innovation.By integrating stimuli-responsive functional units with optical substrates,smart material systems capable of actively modulating light transmittance have been engineered.These technologies overcome the limitations of conventional static shading,demonstrating transformative potential in emerging fields such as smart cockpits for new energy vehicles,dynamic façades for energy-efficient buildings,and flexible displays for wearable electronics.Leveraging multi-physics coupling mechanisms(e.g.,electric/thermal fields),dimming systems achieve millisecond-scale transmittance switching,adaptive photothermal management,and human-machine interaction,thereby underpinning smart cities and green technology initiatives.This review systematically examines the evolutionary principles and industrial pathways of mainstream dimming technologies,focusing on four key approaches:polymer-dispersed liquid crystal(PDLC),electrochromic(EC),suspended particle device(SPD),and dye-doped liquid crystal(DLC).It elucidates their core regulatory mechanisms—including light scattering,electrochemical reactions,particle orientation,and dye-mediated absorption.It synthesizes performance optimization strategies spanning material modification,structural design,and process innovation.The analysis further evaluates the adaptive capabilities of these technologies for dynamic dimming and functional expansion across emerging applications.Critical challenges in industrialization,such as durability,compatibility,and standardization gaps,are assessed,while outlining future trends toward intelligent synergy and eco-conscious manufacturing.This framework aims to guide cross-domain deployment of advanced dimming solutions.关键词
