-SK Chemicals to ramp up production of chemically-recycled PET for food containers
SK Chemicals Co. has ramped up its production of chemically-recycled (CR) PET for the food container market, made by chemically decomposing waste plastics to turn them into pure raw materials and then used for production.
CR PET uses a chemical recycling technology that depolymerizes waste PET bottles to revert them to a raw material state.PET-chain – Chemical-recycling-PET
South Korean chemical company stressed that SKYPET CR is free from pollution by foreign substances while ensuring no deterioration of quality.
SK Chemicals is beginning full-scale operation of the mass production system for the CR PET ‘SKYPET CR’ this month.
SK Chemicals has a business agreement with Jeju Province Development Corp., which manufactures bottled water Samdasoo, to jointly develop chemically recycled PET mineral water bottles.
The company also launched the world’s first commercial production of chemically recycled copolyester. PET-chain – Chemical-recycling-PET
-Shedding light on polymer solar cells: Illuminating how solvent additives improve efficiency
Researchers from Nara Institute of Science and Technology use photoconductive atomic force microscopy to investigate the role of solvent additives in the performance of all-polymer blend solar cells PET-chain – Chemical-recycling-PET
All-polymer blend solar cells are expected to play an important role in the transition to clean energy technologies because they can be easily produced in large-scale flexible sheets. However, their performance has lagged behind that of more traditional silicon alternatives, as well as other organic solar cells.
All-polymer blend solar cells are formed by combining two polymer solutions that solidify into a film on an electrode with in the form of interpenetrating networks, a kind of “phase-separation”. PET-chain – Chemical-recycling-PET
The introduction of solvent additives to the polymer solution has been shown to increase the efficiency of all-polymer blend solar cells. However, the exact process underlying this improvement has not been fully understood. Now, in a study recently published in ACS Applied Polymer Materials, researchers from Nara Institute of Science and Technology have investigated the performance enhancement mechanism using photoconductive atomic force microscopy (PC-AFM). Their findings are expected to help accelerate the widespread application of polymer-based solar cells.
“The empirical nature of solvent additive-mediated efficiency enhancement has hindered the optimization of all-polymer blend solar cell performance, so there has been an urgent need for a greater understanding of the process,” explains senior author Hiroaki Benten.PET-chain – Chemical-recycling-PET
“To that end, we used PC-AFM to interrogate the nanoarchitecture that underpins the performance enhancement.”
PC-AFM is an advanced microscopy technique that allows photocurrents to be visualized with nanometer-scale resolution. The researchers found that trace solvent additives improved the power conversion and photocurrent density of an all-polymer blend solar cell by a factor of up to ~3 by enhancing the ordering and crystallization of the polymer microstructure in the solar cell without damaging the phase-separated structure.
Absorption spectroscopy measurements further confirmed that the trace additives improved the ordering in the polymer microstructures. By forming a network that efficiently transports the photogenerated charges to the external electrode, the flow of photocurrent is increased.PET-chain – Chemical-recycling-PET
