A RADIATION-BASED MODIFICATION METHOD FOR IMPROVING THE WETTABILITY AND MECHANICAL PROPERTIES OF POLYDIMETHYL SILOXANE

摘要

PURPOSE: A radiation-based modification method of polydimethylsiloxane is provided to easily treat at room temperature, to easily control a radiation amount and productivity, and to improve wettability and mechanical properties by only irradiating with radiation. CONSTITUTION: A radiation-based modification method of polydimethylsiloxane comprises a step of manufacturing a polydimethylsiloxane sheet by heat-curing polydimethylsiloxane and a step of irradiating the polydimethylsiloxane sheet with radiation. The radiation is electron beam, gamma ray or ion beam. The energy of the radiation is 0.5-10 MeV. The current density of the radiation is 0.1-10 mA/cm^2. The dose of the radiation is 20-200 kGy.
