This Artificial Intelligence program, combined with a computerized data base, comprises an expert system for the selection/development of wire enamels and other electrical insulating materials. This program could be an indispensable tool and aid for the scientist, freeing him from the necessity of redundant experimentation, due to the vast network of information sharing and the system's ability to suggest promising pathways. This artificial intelligence approach would provide the scientist with sophisticated modeling and complex interactive simulation of chemical reactions and physical properties of potentially useful materials, which would be exceptionally rapid, efficient and cost-effective. Modeling of materials through techniques of artificial intelligence differs from prior computer modeling by creating a unique, accurate conceptual representation of a specific material, as opposed to statistical and purely numerical methods.
该人工智能程序与计算机化数据库相结合,组成了一个专家系统,用于选择/开发线漆和其他电绝缘材料。由于庞大的信息共享网络和系统提出有希望的途径的能力,这个程序可以成为科学家不可或缺的工具和援助,使他从冗余实验的必要性中解脱出来。这种人工智能方法将为科学家提供复杂的建模和复杂的交互模拟,以模拟潜在有用材料的化学反应和物理性质,这将非常快速、高效和具有成本效益。与统计和纯粹的数值方法相反,通过人工智能技术对材料进行建模与之前的计算机建模不同,它可以创建特定材料的独特、准确的概念表示。

A facility was developed in which polymer samples were aged to 32,700 h with an applied load of 6.9 MPa and at temperatures of 70, 110, 135, and 160°C. The aging environment was 0.4 MPa (4 atm) SF6 containing either 4 or 40 Pa (40 or 400 µatm) H2O. The polymers evaluated to 32,700 h were polyethylene terephthalate, polycarbonate, polyparabanic acid, polyethersulfone, and polyimide. Polysulfone and polyetherimide were aged to 11,200 h. Only polyethylene terephthalate showed any interaction with the environment, and this was in the form of higher moisture causing greater reductions in fracture strain. Electrical breakdown measurements were made on most of the aged samples, and there were no reductions in breakdown voltage as a result of aging. The sticking temperatures between polymers was determined to be 160°C for polyethylene terephthalate; 110°C for polycarbonate; 160°C for polysulfone; and >160°C for polyetherimide, polyethersulfone, polyparabanic acid, and polyimide.
研究人员开发了一种设备,将聚合物样品老化至32,700小时,外加载荷为6.9 MPa,温度为70、110、135和160°C。老化环境为0.4 MPa (4atm) SF6,含4或40 Pa(40或400µatm) H2O。评价到32,700小时的聚合物有聚对苯二甲酸乙二醇酯、聚碳酸酯、聚对羟基苯甲酸、聚醚砜和聚酰亚胺。聚砜和聚醚酰亚胺老化至11200小时。只有聚对苯二甲酸乙二醇酯显示出与环境的相互作用,其形式是更高的水分导致断裂应变的更大降低。对大多数老化样品进行了电击穿测量,并没有由于老化而降低击穿电压。对聚对苯二甲酸乙二醇酯测定了聚合物间的粘接温度为160℃;聚碳酸酯110℃;聚砜160℃;聚醚亚胺、聚醚砜、聚对羟基苯甲酸和聚酰亚胺的温度>160℃。

This work was undertaken as a feasibility study with limited actual testing. However, the four synthetic metal/conductive polymer systems studied in polymer thick film applications gave generally favorable results. There are many obstacles to be overcome in order to go from feasibility to practical applications. Prime among these is the need to develop alternative procedures to the conventional screen printed hybrid circuit. Application of these materials as a dispersed phase is not thought to be the best method of utilizing them. A method whereby the application could be as a bulk continuous form would greatly increase the sheet conductivity and possibly eliminate the need to dissolve or disperse. One of several possible approaches would be to utilize existing polymer processing methods, e.g. extrusion molding. The question of ambient stability which has been a fundamental shortcoming of all synthetic metal/conductive polymer technology to date remains to be determined. The limited observations suggest that incorporation of these materials into organic resin systems combined with protective overcoats greatly increase the probability of long-term stability.
这项工作是作为可行性研究进行的,并进行了有限的实际试验。然而,研究了四种合成金属/导电聚合物体系在聚合物厚膜中的应用,得到了普遍良好的结果。从可行性到实际应用还需要克服许多障碍。其中最主要的是需要开发替代传统丝网印刷混合电路的程序。这些材料作为分散相的应用被认为不是利用它们的最佳方法。一种方法,其中应用可以作为一个整体连续形式,将大大增加片的导电性,并可能消除溶解或分散的需要。几种可能的方法之一是利用现有的聚合物加工方法,例如挤出成型。环境稳定性问题是迄今为止所有合成金属/导电聚合物技术的一个根本缺点,仍有待确定。有限的观察结果表明,将这些材料掺入有机树脂体系并结合防护涂层大大增加了长期稳定性的可能性。
