Implication

Experimental study demonstrates enhanced surface energy and peel strength in polypropylene films treated with acetone plasma, highlighting improved surface adhesion and stability.

Key Points

To investigate the chemical mechanisms, reactive sites, and adhesive stability of polypropylene surfaces modified by plasma-induced photochemical reactions using acetone and acetone/oxygen mixtures.
Treated polypropylene films with acetone and acetone/oxygen plasma, including reactive site masking using nitrogen plasma pretreatment.
Characterized chemical changes and surface morphology via ATR-FTIR spectroscopy, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM).
Assessed surface energy, peel strength, and the degradation effects of material aging on the modified films.
Plasma treatment with acetone and acetone/oxygen produced significant increases in polypropylene surface energy.
ATR-FTIR analysis of C−H stretch vibration intensities identified specific reactive sites responsible for photochemical modification.
Nitrogen plasma pretreatment successfully masked reactive surface sites, while modified films exhibited enhanced peel strength across aging intervals.
