DEVELOPMENT OF POLYOLEFIN-BASED MULTIPLE AND REVERSIBLE SHAPE MEMORY POLYMERS [PDF]
, 2019 A shape memory polymer (SMP) is stimuli-responsive with the fantastic capacity to “memorize” a temporary shape under certain conditions and to recover to its permanent shape upon exposure to certain external stimulus (e.g.

Small, EarlyView.A polysulfide‐regulating covalent organic framework (TUS‐44) integrating tetrathiafulvalene and crown‐ether linkers forms an electron‐delocalized, ion‐coordinative network that synergistically mediates Li–S redox chemistry. When interfaced with graphene, the TUS‐44@G layer functions as a catalytic and chemisorptive interface, enabling efficient ...

Visualisation and analysis of polyolefin multilayer coextrusion flows
, 2015 Flow visualisation studies were preformed to determine process parameters initiating interfacial instability in the coextrusion of polyolefin melts. Slit coextrusion visualisation cells with 30° and 90° convergent streams were studied.

Transformative Chemistry, EarlyView.Through a high‐throughput simulation of 3141 COF/lithium salt systems, we reveal that reducing framework weight universally enhances ionic conductivity. Key to performance is the matching of pore chemistry with specific anions; notably, we discover an anion‐driven “shuttle” cooperative transport mechanism, which proposes new principles for designing ...

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms
The Chemical Record, EarlyView.Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

G.: Miscibility of polyolefin blends
, 1999 : Phase separation in polymers is important for many technical applications but is difficult to predict theoretically. Recently, extensive experimental studies on the miscibility of polyolefins revealed that these systems display a wider variety of ...

Journal of Vinyl and Additive Technology, EarlyView.A novel bio‐based stabilizer system significantly improves the quality of polyolefin recyclates during multiple recycling cycles. ABSTRACT This study introduces a novel bio‐based stabilizer system for polyolefin recyclates that combines alditols with small amounts of α‐tocopherol as a sustainable alternative to conventional phosphite additives. The aim
