There are several factors that influence the overall rate of degradation, in addition to pH and copolymer composition. In general, polymer degradation is accelerated by greater hydrophilicity in the backbone or end groups, lesser crystallinity, lower average molecular weight, and smaller size of the finished device.

Which type of material is the hardest ceramics polymer or metals?

Ceramics are very brittle, they tend to fracture under a load which means they are lacking in ductility. Polymers are the softest material due to their complex structure, while ceramics are the hardest but are not very tough because they fracture before plastic deformation occurs.
