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.","PeriodicalId":188957,"journal":{"name":"1985 EIC 17th Electrical/Electronics Insulation Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126146536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":188957,"journal":{"name":"1985 EIC 17th Electrical/Electronics Insulation Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115551532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":188957,"journal":{"name":"1985 EIC 17th Electrical/Electronics Insulation Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121560587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
