Department of Chemical Engineering, SRMIST 13-02-2023 3 LITERATURE REVIEW S.No Title Author/Journal Published Year Observation 1 Ultrafiltration membranes from waste polyethylene terephthalate and additives: synthesis and characterization Smitha Rajesh and Zagabathuni 2013 Membranes manufactured with PET without additives are rigid and have poor mechanical properties. Thus, polyvinylpyrrolidone (PVP) was added, but this change alone did not improve the mechanical properties of the membranes sufficiently. PEG is a known and proven additive for membranes with a wide range of polymers 2 Model analysis on the effect of temperature on the solubility of recycling of Polyethylene Terephthalate (PET) plastic Syed Shujaat Karim, Lai Fatt Chuah 2022 The solubility of a polymer in a solvent depends on its chemical structures, as in general, similarities in structure favour higher solubility. The solubility parameters were introduced to express the enthalpy of mixing, which is the key factor in determining the dissolution of polymer in a solvent 3 Utilization of used polyethylene terephthalate (PET) bottles for the development of ultrafiltration membrane Samuel P. Kusumocahyo , Syarifa K. Ambani 2022 The use of pure water as the non-solvent resulted in a membrane with many defects because phenol which is highly soluble in water diffused rapidly from the polymer matrix into the water creating defects in the membrane structure. 4 Characterization of polyaniline thin flms prepared on polyethylene terephthalate substrate Yuliia  A.  Stetsiv , Mykhailo  M.  Yatsyshyn 2020 PET strates were washed with acetone and dried in the open air. Purpose of treating PET with acetone is for removal of moisture from the PET 5 Effect of PVP on the characteristic of modified membranes made from waste PET bottles for humic acid removal Nasrul   Arahman , Afrillia   Fahrina , , 2017 The presence of PVP in a polymer system has an effect on the pore structure and flux of the PET membrane. The addition of PVP improved pore density with a narrow pore structure and using a high temperature of evaporation resulted in a membrane surface with smaller pores.
