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.

在化学系大分子、超分子和纳米化学项目的支持下，特拉华大学的Thomas H.Epps、III和Michael T.Klein教授以及罗文大学的Joseph Stanzione教授将合作开发将木质素生物油转化为聚合物的合成途径和计算工具。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，从自然和可再生资源中制造新的塑料材料这一重大挑战。通过本研究生产的木质素基聚合物在涂料、表面涂料和其他复合材料中具有潜在的用途。该项目在合作实验室环境中为学生提供研究机会，包括未被充分代表的本科生和经济困难的高中生，并让学生接触制造新的“生物可再生”塑料的现代概念。该项目专注于开发高效且经济实惠的方法，从一种基于木质素的可再生资源中生产“设计师塑料”。木质素是制浆和造纸工业的廉价天然废物。该项目的主要任务包括：1)基于木质素的生物油组成随热解条件和木材组成/来源变化的计算模拟；2)单独或共同对生物油的主要组分进行功能化处理，以从木质素废液中生成多功能单体库；3)合成均聚物(由单一类型的木质素改性单体合成)或杂聚物(从生物油混合物中的木质素改性单体合成)；4)自由基聚合形成杂聚聚合物的动力学研究；以及5)设计和制备可作为热塑性弹性体和压敏胶粘剂的可调嵌段共聚物纳米结构。
