Ultralight and porous cellulose nanofibers/polyethyleneimine composite aerogels with exceptional performance for selective anionic dye adsorption

Researchers developed a new ultralight and porous aerogel made from cellulose nanofibers and polyethyleneimine. This aerogel excels at selectively adsorbing anionic dyes like Methyl Orange, showing high adsorption capacity and rapid filtration performance, making it a potential candidate for wastewater treatment.

Chemically induced repair, adhesion, and recycling of polymers made by inverse vulcanization

This paper demonstrates a method to repair, adhere, and recycle sulfur-rich polymers at room temperature using nucleophiles like pyridine and tributylphosphine. The process involves catalyzing S-S bond exchange, enabling the materials to be rejoined or reshaped without significant heating, opening up possibilities for new applications in adhesives and additive manufacturing.

A comparative study of the crystallinity of Polyetheretherketone by using density, DSC, XRD, and Raman spectroscopy techniques

This study compared four methods for measuring crystallinity in PEEK: density, DSC, XRD, and Raman spectroscopy. Results showed that each method yields different crystallinity values, with DSC overestimating and XRD underestimating compared to density. Four Raman spectral indicators were found to correlate strongly with density-derived crystallinity.

Progress on Polymer Composites With Low Dielectric Constant and Low Dielectric Loss for High-Frequency Signal Transmission

This review summarizes the progress in developing polymer composites with low dielectric constant and loss for high-frequency signal transmission. It discusses various strategies like molecular structure design, filler incorporation, and interface engineering to improve the dielectric properties of polymers, highlighting the importance of balancing adhesion and dielectric performance.
