Research:Polymer-nanoinorganic hybrids are new paper-coating materials that could potentially improve the coating smoothness, gloss, printing quality, and scratch properties of coated papers. The basic idea is to combine the properties of an inorganic nanoparticle with those of the polymer system in an advantageous way, e.g., merging the thermal stability, the mechanical strength, or light scattering power of the inorganic nanoparticle with the elasticity and the ability of the polymer to form films.Most polymer-nanoinorganic hybrids are available only in bulk form and there are few water-based nanohybrid suspensions available. Water-based suspensions are desirable for environmental reasons as well as being required for most paper-coating and some painting applications. The focus of this research is to develop both fundamental understanding of the synthesis of water-based and polymer encapsulated nanohybrid suspensions, and the technological development of using the methodology for paper coating. Both emulsion and miniemulsion polymerization techniques will be tested for polymer encapsulated nanohybrid synthesis. Within these suspension particles, the nanoclay is exfoliated by the polymer matrix. The fundamental understanding of the nanoparticle encapsulation, exfoliation, and the physical properties of the final nanohybrids can also be used to guide other encapsulation reactions such as ink, toner, etc.Impact:The PI has an educational plan to establish a program that is capable of providing outreach activities to local communities and colleges in the Atlanta area. In addition, developing this environmentally benign technology could be of great benefit to the pulp and paper industry.

研究：聚合物 - 纳米有机杂种是新的涂料材料，可能会改善涂层纸的涂料平滑度，光泽度，印刷质量和刮擦性能。基本思想是将无机纳米颗粒的特性与聚合物系统的特性相结合，例如，将无机纳米颗粒的热稳定性，机械强度或光散射能力融合到弹性和最少的膜的能力。纳米杂交悬浮液可用。出于环境原因，理想的水基悬架以及大多数涂料和某些绘画应用所必需的。这项研究的重点是既要发展对水基和聚合物封装的纳米杂化悬浮液的合成的基本理解，又要对使用该方法进行纸张涂层的技术发展。乳液和微型聚合技术均应测试聚合物封装的纳米杂化合成。在这些悬浮颗粒中，纳米粘土被聚合物基质去除。对纳米颗粒封装，去角质和最终纳米杂化物的物理特性的基本理解也可用于指导其他封装反应，例如墨水，碳粉等。影响力：PI具有教育计划，可以建立一个能够为Atlanta地区的社区提供外展活动的计划。此外，开发这种环境良性技术可能对纸浆和造纸业有很大好处。
