Understanding zwitterionic ring‐expansion polymerization through mass spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Zwitterionic ring‐expansion polymerization (ZREP) is a polymerization method in which a cyclic monomer is converted into a cyclic polymer through a zwitterionic intermediate. In this review, we explored the ZREP of various cyclic polymers and how mass spectrometry assists in identifying the product architectures and understanding their ...

Degradation strategies for structural characterization of insoluble synthetic polymers by mass spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract With the advent of soft ionization techniques such as electrospray (ESI) and matrix‐assisted laser desorption/ionization (MALDI) to produce intact gas‐phase ions from nonvolatile macromolecules, mass spectrometry has become an essential technique in the field of polymeric materials.

Friction and Wear Characterizations in Electrospun Nanofibrous Scaffolds for Cartilage Engineering

open access: yesNano Select, EarlyView.
Articular cartilage (AC)‐engineered electrospun scaffolds have experienced a surge in interest in publication in recent years. However, nanofiber frictional properties are poorly explored in the existing literature. We evaluated the effect of countersurface, speed, and hydrophilicity on nanofibers.

Improvement of thermal, electrical, and tribological performances of GnPs composites produced by selective laser sintering

open access: yesPolymer Composites, EarlyView.
Production of the GnPs/PA‐12 particle composites through the SLS system lead to improvements up to 81% in wear resistance, 33.6% in thermal performance and showed a hydrophobic behaviour (43.3% increase of the contact angle) compared to the bare PA‐12 matrix.

Visualizing the selective localization of carbon nanotubes in immiscible polymer blends

open access: yesPolymer Composites, EarlyView.
The in‐situ visualization of 80/20 Polyvinylidenefloride/Polystyrene system with MWCNT is shown. The evolution of torque during the mixing is shown along with the photographs of the blend at each stage. Abstract This paper examines the migration mechanisms of multiwalled carbon nanotubes (MWCNTs) in 80/20 polyvinylidenefloride/polystyrene (PVDF/PS) and

Sustainable hemp fiber reinforced polylactic acid/poly(butylene succinate) biocomposites: Assessing the effectiveness of MAH‐g‐PLA as a compatibilizer

open access: yesPolymer Composites, EarlyView.
Production of biocomposites. Abstract The unsustainability of petroleum resources and the growing issue of plastic pollution necessitate the development of sustainable biocomposites as alternatives to synthetic materials. On this basis, a blend of biosourced poly(lactic acid) (PLA)/poly(butylene succinate) was reinforced with hemp fibers (HF) in ...

Modeling short fiber reinforced polymer matrix composite materials using material designer

open access: yesPolymer Composites, EarlyView.
Modeling Short Fiber Composites: A Material Designer Approach. Abstract In the present era, the importance of simulations pertaining to production is increasing in terms of cost, human resources, and time. As the majority of existing studies on polymer matrix composites are experimental, the development of a modeling approach for these materials will ...
