Structure and mechanical investigation of the effect of proton irradiation in Makrofol DE 7-2 polycarbonate

► Makrofol is a candidate for applications requiring its bending without breaking. ► The carbonyl groups (CO) are the most sensitive groups to proton irradiation. ► The irradiation of Makrofol causes crosslinking that increases the molecular mass. ► The standard chains and a great number of chain ends weaken under proton irradiation.
