Simple method to analyze the molecular weight of

2021-3-1  In this paper, we propose a novel method for the instant measurement of polymer molecular weights using electrochemistry. This approach is based on the cyclic voltammetry (CV) measurements of redox species in a polymer solution using a Au ultramicroelectrode (UME). The Au UME was used to measure the steady-state currents ( iss ), which were

Multiobjective Optimization Method for Polymer Injection

To solve the quality problem of polymer injection parts, a quality prediction and multiobjective optimization method is established. In this method, the parameters that have an important effect on the part quality are selected using an orthogonal testing method, and then a central composite design experiment is performed using these parameters.

Polymerization an overview ScienceDirect Topics

Shaofen Li, in Reaction Engineering, 2017. 12.1 Overview. Polymerization is a process converting low molecular weight monomer to high molecular weight polymers. Due to their significant performance of plasticity, fiber forming, film forming, high elasticity, etc., which low molar mass monomers do not possess, polymers can be widely used for plastics, fibers, rubber, coatings, adhesives, etc

Simple Rheological Analysis Method of Spinnable-Polymer

2015-7-5  Rheological characterization of polymers explains the flow behaviour and viscoelastic properties and tests fibre-forming ability. The current method investigates the viscoelastic properties and morphology of polymers and finds the rheological data and the right polymer viscosity, which is determining the best processing temperature. The right processing temperature saves the power, the

Assisted alignment of conjugated polymers in floating film

2021-9-30  Template-assisted alignment using pre-patterned substrates has been widely used to orient various polymers irrespective of their orientation capability. In this work, we report that using the floating film transfer method, the orientation of guest polymers can be in-situ assisted via blending with a host polymer during film fabrication.
