Reactor-Made Polypropylene for 3D Printing: A Low-Crystallinity Approach
Abstract: 3D printing is technology that enables the complex structure, which is difficult in conventional technique. However, relatively slow manufacturing process and using of limited polymeric material leads to attention of scientist towards newer cost-effective material and technology. In this study, we overcome this issue by synthesizing reactor-made polypropylene (mPP) using Dimethylsilylene-(cyclopentadienyl) (fluorenyl)-zirconium-dichloride metallocene catalyst. The polymerization process was systematically optimized by varying Al/Zr molar ratios, catalyst concentrations, and temperatures to …

Wettability of carbon fibers with resin matrices from dynamic contact angle measurements
Abstract: Wettability is the property that quantifies the propensity of a solid surface (carbon fiber) to be covered by a liquid (resin). For a wettable solid, the solid-liquid contact is favoured and as a result the liquid spreads on such surface of the solid. Spreading of the liquid on the solid surface is primarily driven by the adhesive forces between the liquid and the solid, while the inter molecular cohesive forces …
