Development of composite membrane PBAT: Zeolite Y for application as rhynchophorol release system

Abstract

Composite membranes consisting of biodegradable poly(butylene adipate‐co‐terephthalate (PBAT) and zeolite Y (0–10 wt %) were produced by extrusion. Zeolite Y is well dispersed in the membrane up to 5 wt %, but tends to agglomerate at higher contents. The presence of zeolite Y in the composite resulted in an improvement of the thermal stability, mechanical properties, and increased the barrier properties. The interaction of the composite membranes with rhynchophorol was investigated by different techniques, showing that the semiochemical progressively lixiviates PBAT monomers, causing thermal and mechanical properties to decrease. However, no interaction seemed to occur between the rhynchophorol and the zeolite. Studies of diffusion of pheromone through membranes have shown that the addition of the zeolite Y has not contributed significantly to a decrease in the release rate of rhynchophorol, but the presence of the zeolite Y helps to increase chemical, mechanical, and thermal stabilities of the membranes. © 2017 Wiley Periodicals, Inc.

Controlling the Uptake and Release of Semiochemicals in Channel‐Type Metal‐Organic Frameworks Through Pore Expansion

“…This suggests that inclusion of hydrophobic semiochemical guests is stabilising these MOFs towards hydrolytic decomposition by airborne moisture, something we have observed previously with IRMOFs. [23] Whilst previous studies have demonstrated that porous materials can be used to extend the release shelf-life of semiochemicals, [13][14][15][16] the zeolite or polymer materials used make it difficult to tune the rates to enable identification by and attraction of the target pest. The release profiles observed in this study clearly demonstrate the advantage of using MOFs, and potentially other modular porous materials such as covalent-organic frameworks or hydrogen-bonded organic frameworks, [48,49] for the uptake and release of these chemicalsfacilitating control over the uptake and release rate through pore engineering.…”

“…To combat this issue, a method to slow down and control the release of semiochemicals is desired. [12] Previous studies have examined porous materials, such as zeolites or crosslinked polymers, as potential solutions with some success, [13][14][15][16] but the lack of structural tunability with these materials makes controlling semiochemical loading and release difficult to achieve.…”

Evaluation of the performance of porous PBAT/modified zeolite composite materials for adsorption of Pb(II) ions from wastewater

“…Poonsub Threepopnatkul et al 24 developed PBAT/zeolite 13X membranes to extend the shelf life of bananas. Paulo Romano Cruz Correia et al 25 prepared the obtained PBAT/zeolite Y membrane for controlling the release of lingual phenol pheromone. David Picón et al 26 developed the PBAT/zeolite film was also used to eliminate tetracycline and methylene blue from water.…”

Adsorption of Methylene Blue and Tetracycline by Zeolites Immobilized on a PBAT Electrospun Membrane

“…PBAT and zeolites have been combined to produce composites with different applications: PBAT/zeolite 13X film was developed to increase the shelf life of bananas [35], and PBAT/zeolite Y films capable of controlling the release of rhynchophorol pheromone [36]. PBAT/synthetic zeolite films were also used to develop biodegradable active packaging with ethylene scavenge properties [37].…”
