Summary, etc. Surface modification of polymers by X-rays produced from laser plasma can put a wide range of changes and are magnificently used in effectively all industries ranging from coatings, semiconductors, household appliances, automotive, and biomedical implants. Polymeric materials commonly have outstanding bulk physical and chemical properties. Different properties like electrical, chemical and physical properties can be modify when an extreme dose of X-rays is exposed on the surface of polymers. Currently X-rays are irradiated on the surface of two different polymers including polypropylene and polyethylene. These X-rays are detected with pin photodiode (BPX-65), generated from laser generated Cu plasma where Nd: YAG laser (1064 nm, 10 mJ) is focused on copper. Polymer surface is exposed to X-rays by different shots of laser which are varied from 100 to 400 with a gap of 100. Morphological structure has been studied by using optical microscopy and four point probes are used for studying the resistivity and conductivity. It has been observed that irradiation of X-rays from laser produced plasma produce changes in the bonding structure of polymers due to cross linking and chain-seasoning which are highly responsible for breakage or formation of a bond. A similar type of a result is deduced from four-point probe method that the resistivity of polymers is decreased due to the breakage of the H-C bond.
