Diglycerides of Natural Phenols and Organic Acids for Enhanced Biological Activities

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Diglycerides of natural organic acids and phenols were synthesized regio‐selectively. Diglycerides are structurally similar to cell membranes and are expected to exhibit cell affinity and permeability. The flexible glycerol linkers allow the diglycerides to exhibit not only the physiological activities of each constituent organic acid but also the ...

Coordinative Ring‐Opening Polymerization of Limonene Carbamate towards Phosgene‐ and Isocyanate‐Free Polyurethane

open access: yesAngewandte Chemie International Edition, Accepted Article.
This study presents a phosgene‐ and isocyanate‐free route for the synthesis of polyurethanes using (R)‐limonene as a bio‐based starting material. The synthesis of the cyclic limonene‐based carbamate monomer LU is achieved in high yields using dimethyl carbonate as a sustainable, less hazardous phosgene surrogate and is verified by NMR, SC‐XRD, ESI‐MS ...

Chitosan‐Silanized Hexagonal Boron Nitride Nanocomposite Films and Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT In this study, chitosan‐silanized hexagonal boron nitride (hBN) nanocomposite films were developed using the solution casting method. Unlike chitosan‐hBN studies, silanization of hBN with Vinyl trimethoxy silane (VTS) formed hydrogen bonds. In the swelling ratio, an improvement of 18.6% was observed with the addition of hBN compared to pure ...

3D‐Printable Polymer Composites With Unmodified Boron Nitride for Thermal Management in Flexible Electronics

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Flexible high‐performance electronics are facing the challenge of managing increasing thermal loads in the latest devices. This study presents a one‐step method for 3D printing flexible boron nitride (BN) polymer composites via vat photopolymerization, enhancing thermal conductivity by 270% to 0.8 W m−1 K−1 and improving dielectric properties (

Influence of Thermoplastic Polyurethane Content on Interlaminar Adhesion of Hot‐Pressed Aramid Fabrics

open access: yesJournal of Applied Polymer Science, EarlyView.
Optimized hot‐pressing conditions (200°C, 10 MPa, 25 min) were identified using a DOE approach. Two TPU layers (29.9 wt%) achieved the best interlaminar adhesion, yielding a 67% increase in T‐peel strength. Dynamic mechanical analysis revealed lower activation energy at optimal composition, indicating improved fiber‐matrix interaction.
