Smart materials are one of the most important researching directions in development of High-tech new materials. Their properties can react to reversible changes in their environment by an external condition. Smart materials help in removing the boundaries between structural and functional materials, which may result in significant revolution in materials science development. Based on its significance, WCSM2021-Singapore is dedicated to provide a platform to make up a dialogue between industries and academic organizations and technology transfer from research to industry. WCSM2021-Singapore plans to shoot for 300+ oral presentations in breaking research of Smart Materials Science and Technologies. 500+ world-renowned experts, academicians, senior scientists, industry executives and project leaders from 40+ countries will get together to address the topics, issues, best practices and trends necessary to make the right decisions to guide their business strategies, and future science and technology direction. Meanwhile, it provides exhibition opportunities for industries to showcase their products and services with Smart Materials Science applications.
