“…[21,[44][45][46] The contact angles obtained for the untreated PLA using the four test liquids are 73.4º, 52.2º, 40.9º and 76.7º for water, formamide, diiodoemethane and glycerol respectively. It should be considered that a surface with a water-contact angle between 0 and 30º can be considered as hydrophilic whilst, a hydrophobic surface is characterized by contact angles over 90º.…”

“…This technique uses corona discharge which forms a highly reactive gas that reacts with polymer surfaces primarily by breakage of H-C bonds [140,141]. Consequently, polar groups, such as carbonyl and carboxyl groups are produced [141][142][143][144][145][146][147][148][149][150][151]. When this method was applied to paper, aldehyde groups but not carboxyl groups were formed and surprisingly the water sorption decreased slightly.…”

Paper is a widely used packaging material and is nowadays regaining importance, e.g., as bio-based and biodegradable material. Moreover, new technologies such as polymer-fiber composites, printed electronics and the deep drawing of paper are developing. The process stability and also the resulting quality of paper converting processes such as coating, metallization, printing, and the printing of electronics are highly affected by the hygroexpansion of paper. In order to reduce production instability and to choose and develop paper substrates with ideal characteristics, critical parameters need to be known. This paper offers an extensive overview of those parameters, starting at a molecular and microscopic level with the effect of the constituents and morphology of single fibers, before moving on to paper contents, chemical modifications and additives and finally concluding with paper production and fiber network modification. It was found that the major influences are single fiber sorption, inter-fiber contacts, microfibril angle, fiber morphology (length, width, curliness) and fiber orientation. This review gives new ideas and insights for technologists working in research, development and production optimization of paper-based products.

“…The maximum error in the contact angle measurement did not exceed ±3%. Four different test liquids were selected for contact angle measurements and surface energy calculation by the Owens‐Wendt method 30. These test liquids were selected to cover a wide range of polar (γ l p ) and dispersive (γ l d ) components of the total liquid surface energy (γ l ).…”

In this work, surface modification of low density polyethylene (LDPE) film has been carried out to optimize adhesive joints with polyolefin foam for uses in technological applications. LDPE films were modified in a continuous way using corona discharge plasma with different powers, ranging from 200 to 600 W and several film advance rates in the 5-20 m min À1 range. Changes in surface wettability have been studied with contact angle measurements and subsequent solid surface energy calculation. A polyurethane adhesive was used to join the LDPE film to a polyethylene foam. Mechanical performance of the adhesive joints has been determined by T-peel tests and also the aging effects of several hydrothermal conditions have been studied to evaluate the usefulness of these laminate composites in technological applications. Results show that corona discharge powers between 400 and 600 W are suitable in terms of wettability improvement; on other hand, a slight decrease in surface wettability as the film advance rate increases is detected but the overall changes as a consequence of the film advance rate in the 5-20 m min À1 range are small if compared to changes derived from working powers in the 200-600 W range. Adhesive joints offer excellent mechanical performance and good durability in hydrothermal conditions thus being appropriate for technical applications.
