Nanocomposites based on polylactic acid (PLA) Reinforced by functionalized carbon nanotubes (CNT)
Within biodegradable natural polymers, thermoplastic materials based on polylactic acid (PLA) have been studied over the last decades for their possible use in different kinds of industries such as packaging, textile, biomedicine, engineering, etc. However, PLA has certain disadvantages compared wit...

Within biodegradable natural polymers, thermoplastic materials based on polylactic acid (PLA) have been studied over the last decades for their possible use in different kinds of industries such as packaging, textile, biomedicine, engineering, etc. However, PLA has certain disadvantages compared with synthetic materials, in particular low elongation at break and fairly fragility. To solve this problem some investigations have attempted to incorporate different micro/nano size particles in order to reinforce matrices developed by this polymer. Carbon nanotubes (CNT) are one of the fillers with high potential for industrial use; however, their use as reinforcing material has an important difficulty associated with their poor dispersion and bad interfacial interaction with polymer matrices when they are in their neat state. In this way, different types of treatment of carbon nanotubes have been studied in order to improve their dispersion in a PLA matrix. A review of some of those investigations will be presented in this chapter. In particular, the discussion will be focused on the description of different functionalization methods that were used to obtain those objectives.
