Open call to submit your plastics research to our cross-journal themed collections on ‘Plastic Conversion’ and ‘Polymer Upcycling’

The Royal Society of Chemistry has announced an open call to submit your plastics research to our themed collections on ‘Plastic Conversion’ and ‘Polymer Upcycling’.

The Royal Society of Chemistry is committed to sustainable plastics research and has published a policy statement regarding plastic waste. With increasing impact of plastic waste on the environment, it is necessary to research ways in which we can have a sustainable future for plastics.

Plastics research is interdisciplinary and involves a wide range of chemical scientists. As such, we invite you to contribute to our cross-journal themed collections by submitting your work to Journal of Materials Chemistry A, B, C, Polymer Chemistry or Catalysis Science & Technology.

 

Plastic Conversion

Joint themed collection between Polymer Chemistry and Catalysis Science & Technology

 

 

 

Catalysts have been the main driver for the design of ever new polymers with highly diverse and specialized properties. In this themed issue, we aim to highlight research that makes use of catalysis to optimize the reverse. How can we get the most value out of plastic waste? In this quest, we especially welcome manuscripts that address the challenges unique to plastics. These include but are not limited to additive impurities; mixed polymer streams; how to contact the very viscous, high molecular weight polymer with the (micro-)porous catalyst or a cleavage agent and more broadly catalytic conversion of sustainable polymeric materials for a circular plastic economy. Unconventional approaches via photo-, electro- or mechano-catalytic approaches and combinations thereof are also very welcome. We highly encourage to place the work in the context of performance metrics of green chemistry.

Submissions should fit the scope of either Polymer Chemistry or Catalysis Science & Technology. We would suggest that articles focused on synthetic and polymer chemistry aspects would be best suited to Polymer Chemistry, whereas articles focused on catalytic and/or related methodological advances would be appropriate for Catalysis Science & Technology. The collaborative joint special issue recognizes that management of plastic wastes relies on research conducted at the intersection of polymer chemistry and catalysis. You may submit to whichever journal you feel is most relevant to your current research. Please note that your article may be offered a transfer to the alternate journal if deemed more appropriate by the handling editor.

Polymer Upcycling

Joint themed collection between Journal of Materials Chemistry A, B and C

In 2015 alone, the global waste generated by plastic packaging applications was 82.7 metric tons (Mt). Currently, waste management practices for the end-of-life plastics exploit landfilling, industrial energy recovery from municipal solid waste incineration, pyrolysis and recycling. Due to the ubiquity and necessity of plastics in our daily life, the elimination or reduction of plastics is not foreseeable in the near future and fundamentally new science is needed to describe and understand the polymers, interfaces, decomposition and upcycling of plastics. This Themed Collection aims to explore the latest developments in materials characterization, polymer design and synthesis, physical chemistry and molecular understanding of plastic decomposition and transformation that contribute to a broad knowledge base for upcycling waste plastics.

Submissions should fit within the scope of  Journal of Materials Chemistry A, Journal of Materials Chemistry B or Journal of Materials Chemistry C. We welcome high quality studies across all fields of materials chemistry in the form of full Papers, Communications and Review-type articles (Reviews, Highlights or Perspectives) and we invite authors to select the journal that best suits their submission.

Submit your work to Journal of Materials Chemistry A, Journal of Materials Chemistry B or Journal of Materials Chemistry C now!

 

If you would like to contribute to either of these themed collections, you can submit your article directly through the journal’s online submission service. Please add a “note to the editor” in the submission form when uploading your files to say that this is a contribution to the respective themed collection. The Editorial Office reserves the right to check suitability of submissions in relation to the scope of the collection, and inclusion of accepted articles in the final themed collection is not guaranteed.

If you would like more information about the ‘Polymer Upcycling’ themed collection, please email Materials-rsc@rsc.org. For more information about the ‘Plastic Conversion’ themed collection, please email Polymers-rsc@rsc.org.

We look forward to receiving your submissions and showcasing this important research in our collections.

Paper of the month: Supramolecularly cross-linked nanoassemblies of self-immolative polyurethane from recycled plastic waste: high encapsulation stability and the triggered release of guest molecules

Santra et al. use recycled plastic-waste derived monomers to synthesize a redox-responsive self-immolative amphiphilic polyurethane nanoassembly.

 

 

Polymeric nanoparticles have undeniably found numerous applications in fields ranging from medicine to nanoelectronics. Despite the significant progress in the area, there is an increasing demand in chemotherapeutics to construct polymeric nanoassemblies able to encapsulate and deliver cargo on-demand. Most polymeric nanocarriers suffer from uncontrolled disassembly leading to premature, non-specific guest release while often; guests need to be covalently entrapped to achieve high encapsulation stability.

To address these issues, Molla and collaborators developed a strategy that allows upcycling plastic waste to synthesize a redox-responsive, self-immolative amphiphilic polyurethane that assembles into robust, tightly packed nanoassemblies with high encapsulation efficiency and stability. More specifically the upcycled-plastic nanocontainers were equipped with aromatic moieties enhancing their stability, disulfide bonds offering redox response and tertiary amines inducing charge tunability. Triethylene glycol monomethyl ether units were periodically incorporated on the polymer to enhance hydrophilic interactions with water. Computational studies supported that the high encapsulation stability observed in these polyurethane nanocarriers stems from supramolecular cross-linking via π–π stacking and H-bonding interactions. Notably, in a redox environment 70 % of guest release was obtained from the self-immolative polyurethane nanocarriers while significantly reduced release was observed in polymers lacking the disulfide linker and polymers lacking the aromatic component.  The high encapsulation stability was supported by the low leakage coefficient measured in FRET experiments. Pleasingly, zeta potential measurements revealed the generation of nanoassemblies with positive surface charge at a tumor extracellular matrix relevant pH was attributed to the tertiary amine component.

In summary, a plastic waste derived monomer was used as a basis to create robust self-immolative polyurethane nanocarriers with promising biomaterial characteristics such as biocompatibility, triggered release, and environment-specific charge modulation.
