| Abstract | Polymer composite materials (PCM) on polytetrafluoroethylene (PTFE) base are used in many branches of industry. The materials performance properties greatly depend on supramolecular structure of polymer matrix. Using modification methods can control the structure. The purpose of the paper is to study patterns of change in supramolecular structures in PCM on the basis of PTFE under the influence of radiation used. First, X-ray - structural analyses was carried out (there was determined crystallinity degree, the size of crystallites, parameters - a = b in a hexagonal cel, interlayer distance in amorphous area). It showed the nature of supramolecular structure changes depending on the irradiation dose. Secondly, on the wear resistance sample it was shown that change in performance properties is connected with structural changes; and the their degree depends on initial supramolecular structure, its kind and percentage content of the filler and from the dose of absorbed radiation energy. Furthermore, the research of viscoelastic properties sensitive to supramolecular structure changes was carried out. One stated that there is some ordering of amorphous phase structure in the polymer matrix volume, and that resulted in a-maximum decrease. The research will allow purposefully change the supramolecular structure of polymer composite materials to improve the performance of other properties. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
