An esterified pillar[5]arene has been incorporated into a PVC electrochemical membrane. The resulting pH-responsive sensor functions in the range of pH 1 to 4 in a non-linear manner.

Blend reverse osmosis membranes were fabricated using polyvinyl chloride (PVC) with cellulose acetate (CA) as polymer blends. Tetrahydrofuran (THF) and N-Methyl-2-pyrrolidone (NMP) were used as solvents. The membrane polymer solution was cast on a coated woven fabric support material. The prepared membranes have been characterized by SEM and mechanical properties. SEM r...

Abstract The rapid proliferation and intensive use of electronic devices have led to an increase in pollution, such as noise, electromagnetic interference (EMI), radiofrequency (RFI), which cause malfunctions devices. emergence flexible polymer composites has a remarkable potential for shielding depending on their unique characteristics, electrical, thermal, mechanical, magnetic properties, are...

background: the purpose of this work was to investigate the use of polyvinyl chloride (pvc) dyed with methyl red as a high dose radiation dosimetry. materials and methods: commercial pvc films from sabic made from resins pvc57s with thickness of 60 µm and methyl red with a molecular weight of 269.31 were used. irradiation was carried out using a 60co γ-ray generator with sources arranged in rec...

the present study examined the effect of packaging film on the quantitative and qualitative properties of button mushrooms. the three types of packaging tested were a clear polyvinyl chloride box, polyvinyl chloride stretch film and biaxially-oriented polypropylene film (bopp). the five types of moisture absorbers examined were silica gel (2.5 g, 1.25 g), sodium chloride (2.5 g, 1.25 g), and si...

A survey is given of the recent advances in the study of and the present knowledge of the thermal degradation of polyvinyl chloride. The sites for initiation of the thermal degradation, the mechanism of the dehydrochiorination, the discolouration of PVC by heat and the influence of plasticizers on the rate of degradation are discussed.
