Given this special issue’s efforts to highlight the research emanating from HBCUs (Historically Black Colleges and Universities) and the trials and tribulations associated with their research, the authors have presented work associated with the characterization and application of cellulosic materials as renewable products. Despite challenges, the research completed in this laboratory at Tuskegee, a HBCU, hinges upon the many investigations of cellulose as a carbon-neutral, biorenewable material that can potentially replace environmentally unfriendly and hazardous petroleum-based polymers. Although cellulose is one of the most promising candidates, overcoming the challenge of its incompatibility (i.e., lack of good dispersion, interfacial adhesion, etc.) with most hydrophobic polymers due to its hydrophilic nature is critical to usage in plastic products across industries. Chemical isolations via acid hydrolysis and surface functionalities have emerged as new approaches to modulate the surface chemistry of cellulose to improve its compatibility and physical performance within the polymer composites. Recently, we have explored the influence of (1) acid hydrolysis and (2) chemical modifications via surface oxidation to ketones and aldehydes on the resulting macrostructural arrangements and thermal performance and (3) the application of crystalline cellulose as reinforcement agents in ABS (acrylonitrile–butadiene–styrene) composites.

结晶原始纤维素的分离、氧化和应用：可以终结塑料垃圾的天然产物

鉴于本期特刊努力突出 HBCU（历史上黑人学院和大学）的研究以及与他们的研究相关的试验和磨难，作者介绍了与纤维素材料作为可再生产品的表征和应用相关的工作。尽管面临挑战，但在 HBCU Tuskegee 的这个实验室完成的研究取决于对纤维素作为碳中性、生物可再生材料的许多研究，这种材料有可能取代对环境不友好和有害的石油基聚合物。尽管纤维素是最有前途的候选者之一，但克服了其不相容性（即缺乏良好的分散性、界面粘附性等）的挑战。) 由于其亲水性而与大多数疏水性聚合物一起使用对于跨行业塑料产品的使用至关重要。通过酸水解和表面功能进行化学分离已成为调节纤维素表面化学以提高其在聚合物复合材料中的相容性和物理性能的新方法。最近，我们探索了 (1) 酸水解和 (2) 通过表面氧化成酮和醛的化学改性对由此产生的宏观结构排列和热性能的影响，以及 (3) 结晶纤维素作为增强剂在 ABS（丙烯腈）中的应用–丁二烯–苯乙烯）复合材料。通过酸水解和表面功能进行化学分离已成为调节纤维素表面化学以提高其在聚合物复合材料中的相容性和物理性能的新方法。最近，我们探索了 (1) 酸水解和 (2) 通过表面氧化成酮和醛的化学改性对由此产生的宏观结构排列和热性能的影响，以及 (3) 结晶纤维素作为增强剂在 ABS（丙烯腈）中的应用–丁二烯–苯乙烯）复合材料。通过酸水解和表面功能进行化学分离已成为调节纤维素表面化学以提高其在聚合物复合材料中的相容性和物理性能的新方法。最近，我们探索了 (1) 酸水解和 (2) 通过表面氧化成酮和醛的化学改性对由此产生的宏观结构排列和热性能的影响，以及 (3) 结晶纤维素作为增强剂在 ABS（丙烯腈）中的应用–丁二烯–苯乙烯）复合材料。
