Combined Effects of Solar Radiation and High Vacuum on the Properties of Graphene/Polysiloxane Nanocomposites in Simulated Space Environment

Polymer–matrix composites (PMCs) filled with graphene nanoplatelets (GNP) are ultralightweight combined the ability to perform a wide range of functions. These materials interesting for many applications in space environments, including monitoring degradation caused by radiation exposure. Recently, growing interest outer exploration, both unmanned probes and manned vehicles, has encouraged research make great strides facilitate missions, one goal being monitor limit impact highly damaging radiation. With this perspective, we investigate effects simulated conditions on physico-chemical, morphological, mechanical properties elastomeric PMCs made from polydimethylsiloxane (PDMS) matrix embedding pristine GNP or hybrid graphene/DNA filler high sensitivity ionising An analysis PMC stability, outgassing, surface modification is reported samples exposed solar under vacuum (HV, 10−6 mbar). The experimental results highlight stability DNA-modified exposure, whereas morphology affected. On contrary, do not vary significantly conditions.
