This Small Business Innovation Research Phase I project will develop non-thermal, plasma technology to achieve uniform surface modification of plastic materials at atmospheric pressure in air, without need of significant amounts of a carrier gas. This uniform surface treatment can be achieved flexibly and economically on three-dimensional objects of practical size to a multitude of industries. In the program, well-characterized flat surfaces of polypropylene will be subjected to plasma treatment using a matrix of experimental conditions to determine surface modification and damage effects as a function of voltage/current characteristics, plasma source configuration and processing speed. Surface analytical tools such as Scanning Probe Microscopy, Scanning Electron Microscopy, XPS and FTIR will be employed to evaluate changes in surface morphology and surface chemistry. Changes in surface energy will be gaged by standard wetting tests. The program will then examine performance with three-dimensional objects of various size and shape and TPO blends of industrial significance. The proposed program is compelling because the technology offers a major leap forward in surface treatment across a spectrum of major markets. Typically the surface preparation for finishing involves chemical treatment with highly caustic or acidic agents or with organics, imposing concomitant safety and environmental problems. The plasma technology of this proposal can be applied in place of many of these processes. Markets include, for example, sterilization or biological activation in the biomedical field and fiber conditioning in optical and composite-fiber technologies. However, the greatest commercial impact will be to promote better adhesion, whether it be for inks used in labeling, for thin films in electronics or for paints or other coatings to provide color, texture and/or corrosion protection.

这个小型企业创新研究第一阶段项目将开发非热能等离子体技术，在空气中实现常压下塑料材料的均匀表面改性，而不需要大量的载气。这种均匀的表面处理可以在许多行业的实际尺寸的三维物体上灵活而经济地实现。在该计划中，将使用一系列实验条件对表征良好的聚丙烯平板表面进行等离子体处理，以确定作为电压/电流特性、等离子体源配置和处理速度的函数的表面改性和损伤效果。将使用扫描探针显微镜、扫描电子显微镜、XPS和FTIR等表面分析工具来评估表面形貌和表面化学的变化。表面能的变化将通过标准的润湿测试来测量。然后，该程序将检查各种大小和形状的三维对象以及具有工业意义的TPO混合物的性能。拟议中的计划之所以引人注目，是因为该技术在一系列主要市场的表面处理方面实现了重大飞跃。通常，表面处理包括使用高腐蚀性或酸性试剂或有机物进行化学处理，造成伴随的安全和环境问题。这项提议的等离子体技术可以取代其中的许多工艺。例如，市场包括生物医学领域的灭菌或生物激活，以及光纤和复合纤维技术中的纤维调理。然而，最大的商业影响将是促进更好的附着力，无论是用于标签的油墨，用于电子产品的薄膜，还是用于涂料或其他涂层，以提供颜色、纹理和/或腐蚀保护。
