Abstract
There is a growing research interest for carbon nanotube (CNT)-reinforced polymer nanocomposites for biomedical applications due to their improved physicochemical properties, enhanced mechanical properties, and other features required for biomaterials. This chapter presents an overview for recent advancement for the CNT-reinforced polymer nanocomposites as biomaterials and their potential application in various biomedical fields, including hard and soft tissue engineering, biomedical device, etc. A brief overview of various common nano-reinforcements for the polymer matrix has been included. Commonly used methods for the preparation of CNT-reinforced polymer nanocomposites has been discussed. Several polymers used as matrices for the fabrication of CNT-reinforced polymer nanocomposites and their properties are reviewed. Surface modification of CNTs to improve the dispersion and distribution of CNT in various polymeric matrices is discussed, followed by a brief account of commonly used characterization techniques. Potential applications of CNT-reinforced polymer nanocomposites in various biomedical fields have been elaborated. The chapter included an account of the toxicity of CNT and is concluded with some of the challenges and future prospects of CNT-reinforced polymer nanocomposites for biomedical applications.
