Method for hidden marking of transparent polypropylene film

Fracture behaviour of a polypropylene film

Ageing of polymers results from structural modifications at the molecular scale and kinetic modelling must be elaborated from analysis of the phenomenon at this scale. However, the change of mechanical properties results from modifications of structure at larger scale, especially the macromolecular scale (chain scission, crosslinking) and or at the macroscopic scale (skin-core structure linked ...

Thermal simulation for geometric optimization of metallized polypropylene film capacitors

In this paper, we use an analytic model to calculate the losses in the metallized polypropylene film capacitors. The model is validated experimentally for capacitors having the same capacitance but different geometry. For each group of capacitors a temperature distribution in the roll is assumed with the aim of optimizing its thermal performance. It appears that the heating of a long capacitor ...

A Method for Copyright Marking

Previously [1], we demonstrated a method for automated search for query-identical images and their differentiation from the query image closest analogs, based on the previously described nonprobabilistic method for hypothesis generation and verification (HyGV-2D) [2-3] applied to analysis of grayscale (or color) histograms. The HyGV method provides the differentiation between original images an...

A Facile Approach of Thin Film Coating Consisted of Hydrophobic Titanium Dioxide over Polypropylene Membrane for Membrane Distillation

In this work, the hydrophobic modification of TiO2 nanoparticles (HTiO2) was carried out by reacting with dodecylphosphonic acid (DDPA) and hexylamine solution. A facile approach of the self-assembly technique was used for the coating of hydrophobic HTiO2 layer over the microporous polypropylene (PP) membrane. The self-assembled layer was formed between the interface of trimesoyl chloride (TMC)...
