“…[1][2][3] Macromolecular surface modifiers have more interaction between the surface modifier and host polymer to anchor to the host polymer and keep their lasting effectiveness. However, their structure should be designed carefully so as not to hinder the surface modifier to preferred-diffuse to the surface and lower the efficiency of surface modifiers.…”

A surface functionalization polypropylene was prepared by entrapment a copolymer of polypropylenegrafted-poly(ethylene glycol) into polypropylene. The effects of structure of copolymer, contact dies, and content of modifiers were studied. The results of attenuated total reflection infrared spectroscopy(ATR-FTIR) and contact angle measurements indicated that PP-g-PEG could preferably diffuse onto the surface and effectively increase the hydrophilicity of PP. PPw-g-PEG with lower PEG contents, lower molecular weight of PPw and PEG had better selective enrichment on the surface of PP blend film. By grafting of PEG-OH onto the MPP, PP macromolecular surface modifier with better solvent-resistance than that of PEG can be achieved.

“…A number of approaches have been employed to reach this goal, including (a) synthesis of functional polymers with specific composition and architecture; [2][3][4][5][6][7] One example is a novel type of segmented polyurethanes having both fluorocarbon and polyethylene glycol, which shows a range of hydrophobic and hydrophilic properties in response to the polarity of the contacting medium; [4] (b) blending of a virgin polymer materials with small amounts of (macro)-molecular additive; [8][9][10][11][12] (c) surface modification by various chemical/physical treatments. [13][14][15][16] Poly(carbonate urethane)s (PCU) are used as biomedical materials of longterm implants because of their biostability and moderate biocompatibility same as poly(ether urethane)s. [17] The moderate biocompatibility of PCU is due to the hard segment microdomains at the surface because it would keep protein in native or near-native state on adsorption that has the similar size. [18] Polyurethanes with phosphatidylcholine polar head groups are desired due to the advantage of better biocompatibility.…”

Summary: In this article, we designed and synthesized novel segmented poly(carbonate urethane)s containing both hydrophobic fluorinated alkyl group and hydrophilic phosphatidylcholine polar head groups on the side chain. The contact angle measurement, XPS, together with ATR‐IR investigation indicated a reversible overturn of the phosphatidylcholine groups with the movement of the hydrophobic fluorinated alkyl groups when the samples were treated in dry air or water. The change in environment from air to water induced a reorganization of the surface in order to minimize the interfacial free energy, resulting in a macroscopic change of surface wettability. The good environmental responsiveness of such biomembrane‐mimicking films may find successful applications as biomaterials.Environmentally responsive surface using FPCPCU50 as an example; FPCPCU50 coated on aligned carbon nanotube film and dried in vacuum at 50 °C for 7 h and sample c treated in hot water at 80 °C for 1 h.imageEnvironmentally responsive surface using FPCPCU50 as an example; FPCPCU50 coated on aligned carbon nanotube film and dried in vacuum at 50 °C for 7 h and sample c treated in hot water at 80 °C for 1 h.

“…The simplest 2042 V. Ambrogi et al treatment is solvent cleaning, but the degreasing with heptane turned out not to be effective in the strength of adhesive joints (Table 3). Many chemical pre-treatments were reported for polyole ns [39,40]. Polypropylene surface functionalization through gas-phase and solution-phase treatments was the subject of prior studies [41,42].…”

This study was devoted to the investigation of the adhesion of epoxy resins to polypropylene adherends. In particular, the study was carried out as follows: synthesis of both a liquid crystalline (LC) and a bisphenol-A-based resin, their characterization and their further evaluation as adhesives for polypropylene adherends. This was done in order to evaluate the difference between an LC epoxy resin and an isotropic one in adhesive applications. The adherends chosen were neat polypropylene (PP) and polypropylene reinforced with 20 and 40 wt% talc (PP20 and PP40, respectively). The effect of two different pre-treatments (simple degreasing and acid etching) on the polypropylene adherends was also evaluated. It was shown that the adhesion strength of the liquid crystalline adhesive was higher compared to that of the isotropic one. The higher adhesion was related to the extra ductility demonstrated by the LC epoxy resin, which was due to its particular microstructure. Moreover, the acid etching pre-treatment performed on polypropylene adherends prior to bonding improved the adhesion at the interface with the resin. The increased stiffness of the adherends due to the presence of talc turned out to be bene cial to obtain more resistant joints.
