The rheology of confined polymer layers is of great fundamental importance because of its numerous industrial applications, e.g. the use of polymer as an additive to enhance the lubrication effect of two shearing surfaces separated by a very small distance. In the present study, we focus on one specific type of confined polymer system, the so-called polymer brush. A brush consists of many polym...

Additive manufacturing (AM) gives engineers unprecedented design and material freedom, providing the ability to 3D print polymer structures that can change shape. Many of these Shape Memory Polymer (SMP) structures require multi-material composites, and different programmed shapes can be achieved by designing and engineering these composites to fold and unfold at different rates. To enable SMP ...

Additive manufacturing through material extrusion, often termed three-dimensional (3D) printing, is a burgeoning method for manufacturing thermoplastic components. However, a key obstacle facing 3D-printed plastic parts in engineering applications is the weak weld between successive filament traces, which often leads to delamination and mechanical failure. This is the chief obstacle to the use ...

Abstract Linear low-density polyethylene (LLDPE) is a commodity material that has been increasingly used in various open environments owing to its versatile properties. The mechanical and thermal degradation processability properties can be enhanced by blending with other polymers or using different types of fillers adjust such fit the required applications. objective this work investigate poly...

The article presents an analysis of the results experimental studies effect different types a super absorbent polymer additive on strength concrete. study is aimed at effectiveness new type in concrete structures. In course full-scale experiments, it was possible to identify optimum dosage SAP for fine-grained and heavy concretes. addition, showed that remains unchanged if (SAP) 0.5% weight cem...

Abstract Vat photopolymerisation describes resin-based additive manufacturing processes in which ultraviolet light is used to layer-wise solidify liquid resin into a desired 3D shape. If the starting dual-curing formulation object also thermally cured attain its final properties, obtaining either an elastomer or thermoset. Here, we introduce cavity vat photopolymerisation, one photopolymer prod...
