Surface modification of high-density polyethylene by plasma treatment

Noteworthy impacts of polyurethane-urea ionomers as the efficient polar coatings on adhesion strength of plasma treated polypropylene

“…It is apparent from A c c e p t e d M a n u s c r i p t 10 particles which are present in the O 2 plasma can react with created radicals through the plasma and form the polar functional groups on the PP surface. The crosslinking reaction and the subsequent creation of networks from free radicals is another reaction that in Ar plasma occurs more than O 2 plasma [43]. The more crosslinking reaction in Ar atmosphere during plasma treatment may be ascribed to the lack of active species that cause the polar groups.…”

Efecto del tratamiento superficial de fibras de henequén sobre la resistencia interfacial fibra-matriz y en las propiedades efectivas de materiales compuestos termoplásticos

“…Noah and Prud-Homme [U] in a study of characterization of the surface of a tropical wood by XPS, also reported several emission peaks for the carbon atom and they attributed them to the different constituents such as, polysaccharides, lignin and waxes that are present on the surface of wood, each of them containing carbon atoms in different chemical environments. Bany et al [28] carried out a study to characterize the surface of the pulp of paper (cellulose) and they also reported about several emission peaks for the carbon atom. They also assigned these peaks to the different types of bonding on the paper pulp surface.…”

“…Dos alternativas que pueden ser utilizadas para mejorar la afinidad de las fibras naturales con diversas matrices termoplásticas son: a) la modificación de las propiedades fisicoquímicas de la matriz polimérica mediante su funcionalización. Esta funcionalización puede lograrse procesando la resina usando extrusión reactiva (25), mediante la injerción de nuevos grupos funcionales (26) o utilizando tratamientos con plasmas (27,28); b) la modificación de las propiedades fisicoquimicas superficiales de la fibra usando agentes de acoplamiento…”
