Enhanced printability of polyethylene through air plasma treatment

On the Hydrophilicity and Water Resistance Effect of Styrene‐Acrylonitrile Copolymer Treated by CF4 and O2 Plasmas

“…The new surface‐functionalities act as electron donors, which may explain why the curves dropped to negative numbers; indeed, previous reports describe the same phenomenon after using either oxidative or fluorine‐containing plasma treatments . It is important to emphasise that this information is in agreement with prior research findings, where there is a correlation between the surface charge and energy . Despite this being the first report made on styrene‐acrylonitrile surface charge in literature, previous studies on polystyrene (which has a similar chemical structure) claim that PS holds low surface charge densities due to its hydrophobic character .…”

Surface and bulk properties improvement of HDPE by a batch plasma treatment

“…For more advantages of plasma‐treated samples, printability and adhesive property are interested, as supported by the previous publications that the main factors for printability and adhesion with additives are oxygen and nitrogen contents . It was reported by López‐García et al .…”

“…In recent years, there are several reports revealing the improvement of hydrophilicity of PE surface after plasma treatment with different plasma gases . Interestingly, Arpagaus et al .…”

Printing on Polymers

“…The primary factors that determine the printability are substrate properties, determined by its porosity, and surface properties, determined by surface free energy (SFE) (López-García et al, 2013). Other properties of the substrate, which influence the process of printing, are as follows: structural and dimensional, including thickness, smoothness, and surface cohesion; durability, such as breaking load, extensibility, rigidity, hardness, and resistance to bending; optical, whiteness, opacity, and color; hydrophobic and hydrophilic, such as water absorbability or dimensional stability.…”
