Rheological Assessment of Polymer Melts and Networks: From Degradation to Recyclability

open access: yesMacromolecular Rapid Communications, EarlyView.
Rheology provides a powerful analytic tool for tracking polymer degradation and structural evolution across manufacturing, service, and recycling. Linear and nonlinear rheological techniques reveal changes in molecular architecture, network stability, and processing history.

Stability of the interface between two immiscible fluids in porous media

open access: yesElectronic Journal of Differential Equations, 2003
A generalized model has been recently proposed in [3] to describe deformations of the mobile interface separating two immiscible and compressible fluids in a deformable porous medium.

Some models for immiscible displacements in Hele-Shaw cells

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
We study the linear stability of the immiscible displacement of some fluids in 2D and 3D Hele-Shaw cell. We give a method for avoiding the singularities phenomenons which appears in previous papers. In the case of a non - Newtonian fluid displaced by air

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

open access: yesMacromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

Formation and Breakup of an Immiscible Compound Jet with Density or Viscosity Stratification

open access: yesApplied Sciences, 2019
Formation of compound drops by breakup of an axisymmetric compound jet injected from a coaxial nozzle into another immiscible coflowing fluid, at various density and viscosity ratios, is numerically investigated.

Development of Biodegradable Talc‐Filled PBAT/PLA and PBSA/PBAT Binary Blend Films: Effects of Multilayer Architecture and Uniaxial Orientation on Performance

open access: yesPolymer Engineering &Science, EarlyView.
PBAT‐based PLA and PBSA blend films were developed in single‐ and tri‐layer structures with talc and processed via blown film extrusion followed by uniaxial stretching. Multilayer design and MDO significantly enhanced mechanical strength, stiffness, barrier, and UV resistance through chain orientation and strain‐induced crystallization.

Fluid-Fluid Collision for Particle-Based Immiscible Fluid Animation

open access: yes, 2006
Technical report TR06-01. In this paper, we propose a new fluid-fluid collision model for particle-based immiscible fluid animation. Our model consists of two components, namely, colli-sion detection and collision response. An interesting feature is that our model not only can prevent immiscible fluids from mixing with each other, but also can allow ...

Optimizing Atmospheric Pressure Plasma Surface Treatment of Polymer Melts to Achieve Adhesion‐Promoter Free Multilayer Films

open access: yesPolymer Engineering &Science, EarlyView.
Atmospheric‐pressure plasma treatment of the polyethylene melt at the die exit enables direct joining with a polyamide melt without adhesion promoters. After process optimization, the peel strength of the PE/PA laminates increased from 0.03 to 2.92 N/mm.
