Development of Biodegradable Polymers 随着环境保护意识的普及,越来越多的人开始考虑可持续性发展的问题。其中,塑料污染问题成为了人们关注的焦点之一。单一使用传统塑料制品不仅会造成废弃物的海洋污染,还会对环境和自然生态系统造成长期的影响。因此,寻找一种替代品已经成为了当今科技界的迫切需求。 生物降解聚合物(...
and a and b are zero or positive integers, the case where a and b are simultaneously zero being excluded, and chain extended multiblock polymers which polymers are bioabsorbable and biodegradable, these polymeric materials being derived fr... C Daniel,Y Hani,U Gideon - CA 被引量: 377发表: ...
Biodegradable and Biobased Polymers Biodegradable polymers have undergone extensive investigation since the 1970s. They can be either natural or synthetic and can be derived from either renewable or nonrenewable resources. A series of truly biodegradable petroleum-based sy... L Jiang,J Zhang - 《App...
These biodegradable stents, which are made of polymers or metal alloys with or without a drug coating, have the potential to scaffold the artery to allow natural healing to take place, and then biodegrade. The development of this technology has been slow, however several biodegradable stents have...
However, environmental pollution resulting from the use of non-biodegradable polymers and limited availability of petroleum resources have become serious concerns now than ever before. Hence, in the recent past, a significant amount of research has been directed towards finding alternatives to non-...
let’s start off with the fact that not all biobased polymers/plastics are biodegradable. We will clarify the difference between bioplastics and biopolymers a little later in this post. Biobased polymers typically come from renewable sources such as plants, corn, and other biomass starting material...
‘Biodegradable polymers’can be defined as polymers that are degradablein vivo, either enzymatically or non-enzymatically, to produce biocompatible ornon-toxic by-products. These polymers can be metabolised and excretedvianormalphysiological pathways [1]. In recent years, emphasis in biomaterials ...
