“…6 shows the acetic acid diffusion in PVC, and PVC loading with SiO 2 . The results proved that for SiO 2 /PVC there was increasing in swelling and till they were more than (PVC) Figure 6illustrated that there was unsystematic changes of weight gain with SiO 2 loading ratios, but at 10%SiO 2 /PVC was of the lower absorption [22,23].…”

“…7 it was observed that unsystematic changes in weight gain by SiO 2 loading that reflected by the existence of some voids, and cracks after all cases especially with (NaOH). These defects may be related to penetrate of this solution into the structure of polymer systems more than the other liquids under work [22]. Fig.…”

“…It was found that, appearance and disappearance in some bands within range of (600-840cm -1 ), and (1091-1100cm -1 ) that was attributed to the (C-Cl) stretching, (Si-O-Si), and (C-O) stretching [8,16]. There are symmetric increasing in absorbance intensity spectra with SiO 2 ratios attributed to good distribution of inorganic fillers (Symmetric increases), and the increasing in absorbance intensity was due to the increasing of localized states in energy gabs by increasing of SiO 2 ratios [22]. FTIR characteristics of PVC and its composites were explained in Table 6.…”

“…In the simplest case, water or solution enter the polymer systems without interacting with the molecular segment. This case can be represented by "Fick`s law", which assumes that the absorption is a diffusion process only driven by moisture concentration gradient [21,22]. Decreasing in weight gain (%) up to 3%wt for (SiO 2 /PVC) composites has been noticed; that was attributed to the PVC of higher sorption than PVC loaded systems, due to the flexible nature of the chain that creates more free volume in the matrix.…”

In this work, varying compositions of SiO2 micro filler were addedwith the Polyvinyl Chloride (PVC) and samples have been preparedusing film casting technique. The results have been analyzed andcompared for PVC samples with (1 wt%, 3 wt%, 5 wt% and 10 wt%)SiO2 micro filler. Mechanical characteristics such as tensile strength,elongation at break and Young`s modulus were measured for all thesamples, where the tensile strength was increased from 8.39 Mpa forpurified PVC to 16 Mpa for 3% SiO2/PVC composite. Also, thermalconductivity measurement values illustrated that composite materialshave a good thermal insulation at 10 wt. %, thermal conductivity wasdecreased from 0.1684 W/m. K for PVC to 0.1310W/m. K at 10%SiO2/PVC composite. Absorptivity test was also carried out for thesesamples, the results of this study proved that PVC and SiO2-PVCcomposites have low diffusion coefficients ranging from (10-13- 10-10m2/s). Similarly, the dielectric properties like dielectric constant, lossfactor, resistance, and volume resistivity were performed; thedielectric constant was increased from 2.1039 for PVC to 3.658 for3% SiO2/PVC composites, while the dielectric loss factor wasdecreased from 0.0144 for PVC to 0.0137 for 5%SiO2/PVCcomposite. The values of resistance were increased from17259.99(Ω) for purified PVC to 29185.75(Ω) for 10% SiO2/PVCcomposites. Volume resistivity was increased from 0.3794 x109 (Ω.cm) for PVC to 0.5179x109 (Ω. cm) for 10% SiO2/PVC composites.FTIR spectroscopy was employed for all PVC-composite samplesand its results were investigated, there are systematic increases inabsorbance intensity spectra with SiO2 ratios attributed to gooddistribution of inorganic fillers (Symmetric increases). Themicrostructure and morphology of the prepared samples wereinvestigated by using optical microscope. It can be observed that, thesamples with (3% SiO2/PVC) are glossy and smooth withoutagglomeration of (SiO2) particles in (PVC) matrix. The resultsdemonstrate that PVC-composite films prepared in this study showpromising potential to achieve good materials for plastic packagingapplications.

This work describes the weathering effects (UV-Irradiation, and Rain) on the thermal conductivity of PS, PMMA, PS/PMMA blend for packaging application. The samples were prepared by cast method at different ratios (10, 30, 50, 70, and 90 %wt). It was seen that the thermal conductivity of PMMA (0.145 W/m.K), and for PS(0.095 W/m.K), which increases by PS ratio increase up to 50% PS/PMMA blend then decreased that was attributed to increase in miscibility of the blend involved. By UV-weathering, it was seen that thermal conductivity for PMMA increased with UV-weathering up to (30hr) then decreased, that was attributed to rigidity and defect formation, respectively. For 30%PS/PMMA, there results showed unsystematic decrease in thermal conductivity, which was attributed to unsystematic degradation. By Rain-weathering, thermal conductivity PS, PMMA, and 30 %PS, PMMA, it was seen systematic decreased in PS and 30 % PS/PMMA thermal conductivity; and systematic decrease in PMMA thermal conductivity. That due to the water diffusion in the samples that created some voids, bubbles, and results in decrease in thermal conductivity. This result was attributed to the decrease in adhesive between the components of polymer systems. The results suggested that the samples involved could be used for packaging application.

The world is evolving toward extending the life of commodities and decreasing waste by recycling. The purpose of this study is to improve resistance of epoxy against the corrosive conditions by reinforcing it with available chemically resistant and low cost materials. Selection of Glass wastes to reinforce epoxy with 50% by weight. Preparation of four sets of samples for this purpose, two sets of samples make and cure at room temperature, while the others cure at 50°C for two hours. Each set make up of both reinforced and unreinforced epoxy. Immersion of these samples in different environment (Water, NaOH, HCl, Benzene and Kerosene) to find out the resistance of the epoxy after reinforcing. After immersion for six months, it is found that the composite seems more resistance compared to matrix material alone. Composites reinforced by glass particles show an increase in mechanical properties when compared to elegant epoxy resin. Density, Vickers hardness and Modulus of elasticity values increased by (31%, 67% and 62%) respectively for composite at room temperature. Improvement of the resistance after the post curing of unreinforced and reinforced epoxy. The solutions that have highest effect for unreinforced samples at room temperature are (HCl and Water). This indicates that epoxy acquire resistance after reinforcing with glass waste which enables it to be utilize in different applications.
