Iran’s Researchers Fabricate Self-Healing Polymer Sheets Containing Spherical Microcapsules
“In this research, a cost-effective method has been presented with suitable efficiency for self-healing in polymers based on reparative microcapsules by making an electrospraying device and introducing a new way for making multi-core microcapsules with a two-step electrospraying method where both polymer repair and hardening agents are included in a single microcapsule,” said Reza Barbaz Esfahani, a graduate of Amirkabir University of Technology and manager of the project.
“Also, the multi-scale and macro finite element method developed in this research is of great help to researchers and industrialists in assessing the repair efficiency of this category of self-healing systems based on the selected materials,” he added.
Barbaz Esfahani explained that results of the research can be used in all basic and advanced industries that deal with polymers in mechanical loading, adding, “For instance, in medical industry, polymers are used as prosthesis for body parts and in aviation industry, polymers are applied to make the required structures.”
Self-healing polymers (SHP) are the polymers that have the capability to recover the material from any physical damage by responding to the damages or cracks in the material and heal the same.
