1. A composition comprising:
a polycarbonate;
1 to 5 wt % based on a total weight of the composition of a nanosilica having a D50 particle size by volume of 5 to 50 nanometers determined in accordance with ISO-22412-17; wherein the nanosilica has a hydrophobic coating; and
a siloxane domain having repeat units of the formula 10;

OG Complex Work Unit Chemistry
wherein each R is independently a C1-13 monovalent organic group and the value of E is 2 to 1,000;
wherein the composition comprises at least one of
a polycarbonate-polysiloxane copolymer, wherein, if present, the polysiloxane portion of the polycarbonate-polysiloxane copolymer constitutes at least a portion of the siloxane domain, and the value of E of formula (10) is 40 to 80, wherein the polycarbonate-polysiloxane copolymer can be the same or different as the polycarbonate; or
a plurality of polysiloxane particles having a D50 particle size by volume of 0.1 to 10 micrometers determined in accordance with ISO-22412-17, wherein, if present, the plurality of polysiloxane particles constitutes at least a portion of the siloxane domain.
