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.

聚乳酸从结构到应用前景

随着环境限制的加剧，对采用可再生资源而不是有限可用的不可再生资源用于工业目的的需求正在增加。聚合物是几乎所有行业的关键组成部分之一，是各种应用所需来源的先驱。这使得可以从可再生资源中获得的聚合物被广泛研究，并有望在包装工业、医疗领域和汽车工业领域掀起一场革命。聚乳酸（PLA）是一种由乳酸（2-羟基丙酸）衍生的脂肪族聚酯，在食品包装工业、组织支架和生物医学设备中有着广泛的应用。本文着重对聚乳酸、聚乳酸的结构和聚乳酸的各种性能进行了深入的综述。本文还讨论了基于PLA的不同聚合物共混物/复合材料的细节。还对聚乳酸的应用领域、用途和未来的应用范围进行了研究。

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.
