Do we have a space elevator solution here? I’m using the concept in a story and it would be nice if I could use this to explain it. I hate having to use Star Trekian “techno-babble”.

So, the next task is to find other molecules that can replace water in the fabrication process. I am not sure that replacing water in the fabrication process would resolve the papers vulnerability to water.

Sounds a lot like the material description from Roswell incident.

Forget all the fancy-schmancy tech stuff........just develop toilet tissue paper that doesn't dissolve in one's hand before using.

"The super paper does have its kryptonite, however. The sheets remain stable when exposed to air, says Ruoff, but immersing them in water slowly loosens the bonds. Also, says materials scientist Boris Yakobson of Rice University in Houston, Texas, because water is so common as either liquid as rain or vapor as humidity, it will likely affect graphene sheets exposed to the environment in the long run if the material can't be protected from water's effects. So, the next task is to find other molecules that can replace water in the fabrication process.
OR. Equally promising might be to find a substance (or make an artificial one) that would, by its makeup like to bond with graphene. Then a second step in the process could include putting finished sheets through a process - like the "layering" processes used in semi-conductors - that places a coating impervious to water on the the finished sheets. The sheets would still have all the strength and flexibility as before, while - with the exception of major physical damage - not degrade in the presence of moisture. There are many applications - building construction - where such sheets could be very useful and stable. Yes, flying debris from storms, fire or explosions can damage a structure, but when they do the damaged elements of the structure need to be replaced anyway, so it would be no different for properly coated graphene sheets.

Fantastic! Oh, wait, it can’t be exposed to water or it dissolves....No sneezing on graphene oxide spaceships then.
