composites of thermoplastic polymer polyamethyl methacrylate (PMMA) and reinforcement copper particles (Cu), copper oxide (CuO) and weight fraction10%were prepared using chloroform as a solvent by casting method. Some physical properties have been studied, such as: Structural properties(XRD, and optical microscopy), thermal properties (thermal conductivity, thermal stability, calculation of activation energy at different heating rates, and determination of polymer lifetime), and optical properties (absorbance, absorption coefficient, and energy gap).The results of the structural properties were indicate that the rate size of the crystals of the copper was about 360nm and the copper oxide was about 100nm. The researcher observed from the photos of the optical microscope the distribution of the micron material inside the polymer material PMMA uniformly, while the results of the thermal properties showed that the greatest thermal conductivity at (PMMA\/Cu) compared with the (PMMA\/CuO) and PMMA pure. As for the\u00a0 thermal stability study it used the curves of thermal weight measurement (TGA)samples prepared with different heating rates (4, 6, 10)\u2103\/min Turns out that (PMMA\/CuO) had the best thermal stability compared with PMMA pure and (PMMA\/Cu).To calculate energy activation at specific transformation levels, it was found that the activation energy was the best value for the composite(PMMA\/CuO) at (175kJ\/mole) followed by (PMMA\/Cu)at(155kJ\/mole)followed by (PMMA) at )131kJ\/mole). The level of the conversion15%this shows the added effect (Cu, CuO). The survival time of the samples was calculated at 15% conversion rate and based on TGA information. The (PMMA\/CuO) time was better followed by (PMMA\/Cu) and PMMA at all heat bikes. In addition, high temperatures lead to reduced survival<\/span><\/h3>\n<h3 style=\"text-align: left\"><span style=\"color: #993366\">While, \u00a0\u00a0for the optical properties, the highest absorption and absorption parameters were (PMMA\/Cu), (PMMA\/CuO) and PMMA respectively. The results showed that the values of the energy gap of the allowed and prohibited polymer transitions were less than Cu (CuO) and the lowest value of the energy gap was PMMA\/Cu<\/span><\/h3>\n<h4 style=\"text-align: left\"><span style=\"color: #000080\">\u00a0<\/span><\/h4>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>\u0646\u0627\u0642\u0634 \u0642\u0633\u0645 \u0627\u0644\u0641\u064a\u0632\u064a\u0627\u0621 \u0641\u064a \u0643\u0644\u064a\u0629 \u0627\u0644\u062a\u0631\u0628\u064a\u0629 \u0644\u0644\u0639\u0644\u0648\u0645 \u0627\u0644\u0635\u0631\u0641\u0629 (\u0627\u0628\u0646 \u0627\u0644\u0647\u064a\u062b\u0645) \u0631\u0633\u0627\u0644\u0629 \u0627\u0644\u0645\u0627\u062c\u0633\u062a\u064a\u0631 \u0627\u0644\u0645\u0648\u0633\u0648\u0645\u0629 (\u062a\u0623\u062b\u064a\u0631 \u0627\u0644\u0645\u0636\u0627\u0641\u0627\u062a&#8230;.<a class=\"cz_readmore\" href=\"https:\/\/ihcoedu.uobaghdad.edu.iq\/?p=27787\"><i class=\"fa fa-angle-left\" aria-hidden=\"true\"><\/i><span>\u0627\u0644\u0645\u0632\u064a\u062f<\/span><\/a><\/p>\n","protected":false},"author":25,"featured_media":27790,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"no","_lmt_disable":"","footnotes":""},"categories":[44,7,16],"tags":[23],"class_list":["post-27787","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-44","category-7","category-16","tag-ihcoedu"],"modified_by":"ihcoedu","_links":{"self":[{"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=\/wp\/v2\/posts\/27787","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=\/wp\/v2\/users\/25"}],"replies":[{"embeddable":true,"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=27787"}],"version-history":[{"count":0,"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=\/wp\/v2\/posts\/27787\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=\/wp\/v2\/media\/27790"}],"wp:attachment":[{"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=27787"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=27787"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ihcoedu.uobaghdad.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=27787"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
