Improving the Thermomechanical Properties of Sulfur Copolymers through Thermal Treatments |
| 초록 |
Inverse vulcanization provides facile and low-cost synthesis of polymeric sulfur for various potential applications including infrared optics, triboelectric energy harvesting, and energy storage applications. However, their thermomechanical properties such as glass transition temperature (Tg), tensile modulus are insufficient for practical applications. In this presentation, we discuss a simple heat-treatment strategy to enhance thermomechanical properties of sulfur-divinylbenzene (S-DVB) copolymers. The structure-property relationship of sulfur copolymers is developed by a systematic study of thermomechanical property based on time-resolved heat treatments at various temperatures. The dynamic mechanical analysis indicated that the Tg of S-DVB increased from 86 ⁰C to 103 ⁰C and the mechanical properties increased from 1.8 GPa to 2.4 GPa after heat treatment . |
