This proposal targets to carry-out fundamental research on renewable resource-based bioplastics and their value-added biomaterials, to facilitate rapid transition to a biobased economy. Two recently highlighted bioplastics are polylactides (PLA) and polyhydroxyalkanoates (PHAs). They are of particular interest because of their renewable origin, biodegradability and claimed environmental sustainability in reducing green house gas emission. There is a pressing need to enhance the versatility of these emerging bioplastics for more wide spread applications, making them ready to compete with traditional non-biodegradable plastics. A transformative approach in creating a new range of smart biomaterials was initiated by incorporation of nanostructures into bioplastic, including revolutionary material combinations. Integrating the advantage of nanotechnology in bringing-out new sustainable biomaterials is considered a gentle approach. Recent accomplishment by the applicant's research team was utilization of a new technology, based on nanoscopic additive, to create a modified bioplastic which exhibits a unique balance in toughness and stiffness. This discovery is imminent to further explore the science-based knowledge economy for multifunctional bioplastic uses. The science and engineering principles of new bioplastic matrices will be expanded further, using additional reinforcements, such as nano-clay, natural fibres and talc to generate new smart biomaterials. Such materials are called hierarchical nano-biocomposites. The value-added biomaterials from new discovered bioplastics will have applications in greener auto-arts, building products, furniture and rigid packaging. This will not only help in providing additional uses and new markets for agriculture and manufacturing industry, but will also supplement and substitute the existing petroleum-based counterparts. This means a tremendous reduction in green house gas emission through use of biomaterials and reducing our dependency on petroleum. The out-come of this research will create new fundamental knowledge to stimulate additional research. The vision is to educate future students in driving-forward the emerging green technology innovation.

该提案旨在开展基于可再生资源的生物塑料及其增值生物材料的基础研究，以促进向生物经济的快速转型。最近备受关注的两种生物塑料是聚丙交酯（PLA）和聚羟基脂肪酸酯（PHA）。它们因其可再生来源、可生物降解性以及声称在减少温室气体排放方面的环境可持续性而受到特别关注。迫切需要增强这些新兴生物塑料的多功能性，以实现更广泛的应用，使它们做好与传统的不可生物降解塑料竞争的准备。通过将纳米结构纳入生物塑料（包括革命性的材料组合），开创了创造一系列新型智能生物材料的变革性方法。整合纳米技术的优势来开发新的可持续生物材料被认为是一种温和的方法。申请人的研究团队最近取得的成就是利用基于纳米级添加剂的新技术来制造一种改性生物塑料，该塑料在韧性和刚度方面表现出独特的平衡。这一发现即将进一步探索多功能生物塑料用途的基于科学的知识经济。新型生物塑料基质的科学和工程原理将进一步扩展，使用纳米粘土、天然纤维和滑石粉等额外增强材料来生成新型智能生物材料。此类材料被称为分层纳米生物复合材料。新发现的生物塑料所产生的增值生物材料将应用于绿色汽车艺术品、建筑产品、家具和硬质包装。这不仅有助于为农业和制造业提供额外的用途和新市场，而且还将补充和替代现有的石油基产品。这意味着通过使用生物材料和减少我们对石油的依赖可以大大减少温室气体排放。这项研究的结果将创造新的基础知识，以刺激更多的研究。我们的愿景是教育未来的学生推动新兴的绿色技术创新。
