Abstract
The demand for an adoption of renewable resources rather than finitely available non renewable sources for industrial purposes are rising, with the growing environmental constraints. Polymers being one of the crucial part of almost all the industries, pioneer in the list of sources needed for various applications. This makes polymers that can be obtained from renewable sources being studied widely and are anticipated to make a revolution in the field of packaging industry, medical field, and automobile industry. Polylactic acid (PLA) is one among such biopolymers, which is an aliphatic polyester derived from lactic acid (2-hydroxypropionic acid), that find wide applications in food packaging industry, tissue scaffolding, and biomedical devices. This paper focuses on an in-depth review on polylactic acid, its structure, and various properties of PLA. The details of different polymer blends/composites based on PLA are also discussed here. The fields of applications, where PLA is being utilized and the future scopes of the polymer are also studied.
期刊介绍：
Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
