Biodegradable membrane based on polycaprolactone/polybutylene succinate: Characterization and performance evaluation in wastewater treatment

Abstract

Biodegradable membranes with different compositions of polycaprolactone (PCL) and polybutylene succinate (PBS) are prepared via immersion precipitation. The morphology, hydrophilicity, chemical structure, crystalline structure, mechanical properties, and biodegradability of the membranes are studied to assess the effect of PBS concentration in the polymer blend on membrane properties. Furthermore, the performance of the obtained membranes is assessed through the treatment of wastewater sampled from the chips and snacks factory. Also, membranes' antifouling properties are assessed by filtration of a model foulant. The investigations revealed that the addition of PBS to PCL increases the membrane hydrophilicity and biodegradability. Regarding the results, the PCL membrane blended with 30 wt% PBS has 106%, 26%, and 37% higher pure water flux, flux recovery ratio, and permeate flux, in addition to the higher rejection of pollution indices, in comparison with the PCL membrane.

“…However, adding more than 20 wt % of BP had resulted in increased viscosity and irregular pattern of the viscosity curves, which might result from an increase in rigidity of molecular chain and decrease in molecular weight of the blends (Qu et al, 2019). The reduction in viscosity level observed from this study due to an increase in BP and decrease in PBS agreed with a previous study that reported a reduction in viscosity due to a low amount of PBS (Sadeghi et al, 2021).…”

“…These two characteristics peaks obtained from the XRD spectrum, in addition to 21.6 and 29.2 peaks, were similarly reported by Ye et al (2017) after analyzing raw PBS and its blend with urea. Hence, the obtained crystalline structure results showed that the blends were just a numeral superposition and a physical mixture of PBS and BP with a reduced pure PBS crystallinity (Sadeghi et al, 2021) suggests faster degradation of the blends than pure PBS.…”

“…According to a report, the global market for bioplastics is predicted to increase from 1.6 million metric tons in 2018 to 2.7 million metric tons by 2023 2 . Among the many bio‐based polymers, polybutylene succinate (PBS) has been widely used in packaging, 3,4 agriculture, 5,6 electrical and electronic technologies, 7,8 transportation, 9 and medical supplies 10 . This is attributed to the biodegradability and good mechanical properties of PBS 11 (similar to polypropylene and polyethylene 12 ).…”

Study on the Foaming Behaviors of PBS and Its Modification with PA6IcoT Assisted by scCO2

“…[ 1 ] Currently, the majority of the polymer foams are made of polystyrene, [ 2 ] polyurethane, [ 3 ] polyvinyl chloride, [ 4 ] polyethylene, [ 5 ] and polypropylene [ 6,7 ] which have caused environmental concerns due to their limited degradation. Compared with poly(lactic acid), [ 8 ] polycaprolactone, [ 9 ] polyhydroxyalkanoates, [ 10 ] and other biodegradable polymers, poly(butylenes succinate) (PBS) is regarded as the most promising biodegradable polymer material due to its good processability and mechanical properties, better thermal and chemical stability, and lower material cost. [ 11 ] Therefore, preparation of the PBS foams has attracted broad attention.…”
