Shape Memory Materials Poly L Lactic Acid Presentation

Shape memory materials poly L lactic acid (PLLA)
PLLA is a biodegradable and biocompatible polymer. It is derived from renewable resources such as cornstarch or sugarcane. PLLA exhibits shape memory properties, meaning it can return to its original shape when subjected to certain stimuli.	Image Source

Shape memory effect (SME) in PLLA
SME is the ability of a material to remember its original shape and recover it after deformation. PLLA exhibits two-way shape memory effect (2WSME) and one-way shape memory effect (1WSME). 2WSME allows PLLA to return to its original shape both upon heating and cooling, while 1WSME allows shape recovery only upon heating.

Applications of PLLA shape memory materials
Medical implants: PLLA can be used to create temporary or permanent implants that can be easily inserted and molded into the desired shape. Biodegradable sutures: PLLA sutures can be used in surgeries, reducing the need for a second operation to remove them. Drug delivery systems: PLLA can be used to create implantable devices that release drugs in a controlled manner.	Image Source

Challenges and limitations of PLLA shape memory materials
Limited mechanical strength: PLLA has lower mechanical strength compared to other non-biodegradable materials. Processing difficulties: PLLA requires careful processing to achieve the desired shape memory properties. Limited thermal stability: PLLA has a relatively low glass transition temperature, limiting its use in high-temperature applications.	Image Source
