High-performance functionality along with high physical and chemical stability over time are overarching goals of almost all classes of electronics. Negligible variations in physical and chemical properties of materials over time, ensures continuous and reliable operation of electronics; packaging, circuit design, materials selection and device layout are all configured to accomplish this outcome. However, a new concept would be to design sophisticated electronic devices at the same performance level that are capable of undergoing rapid degradation at prescribed time and controlled rate. The sophisticated electronics used in implantable biomedical devices, military and inelegance applications in everything from sensors, radios, data acquisition devices and even phones can now be made at such a low cost that they are pervasive. Many biomedical implantable devices require an extraction surgery once the end of the operation life of the device is reached. In military and intelligence applications, these electronics have become a necessity for operations; but, it is almost impossible to track and recover every device from the operation field. We have developed a novel concept of transient materials in electronic devices with goal of investigating feasibility of transient materials for design and synthesis of substrate and packaging materials for electronic circuits. Transient materials and electronics are capable of dissolving in their surrounding environment with no traceable remains. These devices should maintain full functionality until triggered for degradation. Once triggered to dissolve, the electronics would degrade rapidly at a tunable rate. In this work we have demonstrated precise control over transitory behavior of polymer composites based on biocompatible and biodegradable polymers for potential biomedical applications. We have studied chemical (FTIR) and physical behaviors of these polymer composites and have characterize them for their transiency and mechanical (DMA) properties.
