Biocompatible, biostable aramid, and nanocomposites are commonly used for implanted devices because of their water and gas permeability that protects electronic circuit of the device against the moisture environment as well as the ions that exist in the human body. Aramid composites have attracted significant attention in the applications of soft tissue engineering due to the nature of biodegradability and tunable mechanical features. The nanosized webs and hybrid films of chitosan/m-aramid have been successfully used due to their antimicrobial properties.

In this chapter, a state-of-the art review of biocompatible and biostable aramide and composites is presented. Recent progress and developments of composite processing methodologies and chemical modification techniques are also discussed.
