Elaborating more realistic model microplastics by simulating polypropylene's environmental ageing

Ecotoxicology and Environmental Safety
In this work, we propose a new protocol for producing model microplastics from an industrial polymer and compare it to a conventional method, cryomilling.

Effect of co-monomer on the adhesive performance of PP-g-MAH between cast polypropylene film and aluminum foil

Materials Research Express, 2020
Three functionalized polypropylenes (PPs) were successfully prepared for use as the inner adhesive layer of aluminum/polymer laminated film by melt grafting of maleic anhydride (MAH) on PP with styrene (St), diallyl phthalate (DAP) and triallyl ...

Photodegradation of polypropylenes with clarifying agent

, 2015
The work compared the effect of α-nucleating/clarifying agent based on 1,3;2,4-bis(3,4-dimethylbenzylidene)sorbitol on the photodegradation in two polypropylenes (PP). One of them was nucleated directly by producer while the second in the laboratory. For

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams

Advanced Functional Materials, EarlyView.
A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

Advanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

Long-Term Follow-up of Polypropylene Bone Anchored Slings

International Brazilian Journal of Urology, 2013
Introduction The transvaginal bone anchored polypropylene sling (BAS) has proven to be a successful treatment for patients with SUI. However, there is limited data on long-term outcomes following BAS with polypropylene mesh.

Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain
