Summary form only given. The surface energy and adhesion properties of commodity polymers such as polypropylene (PP) can be modified by functionalization of the surface by plasma-generated radicals and ions. For example affixing fluorine to the surface in a low temperature plasma lowers surface energy and increases hydrophobicity. The F atoms produced in the plasma both abstract H atoms from and adhere...
In this work, an experimental investigation of fluorine gas (F2) plasma treatment of polypropylene (PP) film reveals the evolution of PP fluorination. Surface analysis of fluorinated PP surfaces describes a surface modification process that is initially quite rapid but slows sharply as the fluorination progresses. The fluorination reaction occurs more rapidly at the PP film surface and evidence of...
The surface properties of commodity hydrocarbon polymers such as poly(propylene) (PP) can be modified by functionalization with plasma‐generated radicals and ions. For example, affixing fluorine to a hydrocarbon surface lowers surface energy and increases hydrophobicity. One such process is treatment of PP films in low‐pressure, capacitively coupled plasmas (CCPs) sustained in F2‐containing gas mixtures...
