Under the support of the Macromolecular, Supramolecular and Nanochemistry Program of the Division of Chemistry, Professors Thomas H. Epps, III and Michael T. Klein of the University of Delaware and Professor Joseph Stanzione of Rowan University will collaborate to develop synthetic pathways and computational tools for converting lignin-based bio-oils to polymers. This research aims to address the grand challenge of manufacturing new plastic materials from natural and renewable resources, without depleting food or other commercial resource production. The lignin-based polymers to be produced through this research have potential uses in paints, surface coatings, and other composite materials. This project provides research opportunities to students-including underrepresented undergraduate and economically-disadvantaged high school students-in acollaborative laboratory setting and exposes students to modern concepts for making new 'biorenewable' plastics.This project focuses on developing efficient and cost-effective approaches to generate 'designer plastics' from a renewable resource based on lignin, an inexpensive and natural waste product of pulp and paper industry. The main tasks of this project include: 1) computational modeling of lignin-based bio-oil composition as a function of pyrolysis conditions and variability in wood composition/source; 2) functionalization of the major components of bio-oils separately or collectively to generate versatile monomer libraries from lignin waste streams; 3) synthesis of homopolymers (from a single type of lignin-modified monomers) or heteropolymers (from lignin-modified monomers in bio-oil mixtures); 4) kinetic studies of the heteropolymer formation by free-radical polymerization; and 5) design and preparation of tunable nanostructures of block copolymers that are potentially useful as thermoplastic elastomers and pressure-sensitive adhesives.

在化学系高分子、超分子和纳米化学项目的支持下，特拉华大学Thomas H. Epps, III和Michael T. Klein教授以及罗文大学Joseph Stanzione教授将合作开发合成途径和计算工具用于将木质素基生物油转化为聚合物。这项研究旨在解决在不消耗粮食或其他商业资源生产的情况下，利用天然和可再生资源制造新型塑料材料的巨大挑战。 通过这项研究生产的木质素聚合物在油漆、表面涂料和其他复合材料中具有潜在用途。 该项目为学生（包括代表性不足的本科生和经济困难的高中生）在合作实验室环境中提供研究机会，并向学生展示制造新型“生物可再生”塑料的现代概念。该项目致力于开发高效且具有成本效益的方法来产生“设计塑料”来自基于木质素的可再生资源，木质素是纸浆和造纸工业的廉价天然废品。该项目的主要任务包括：1）基于木质素的生物油成分作为热解条件和木材成分/来源变化的函数的计算模型； 2) 单独或共同对生物油的主要成分进行功能化，以从木质素废物流中生成多功能单体库； 3) 均聚物（由单一类型的木质素改性单体）或杂聚物（由生物油混合物中的木质素改性单体）的合成； 4）自由基聚合形成杂聚物的动力学研究； 5）设计和制备可用作热塑性弹性体和压敏粘合剂的可调节嵌段共聚物纳米结构。
