Isotactic polypropylene with LDPE

Fig. 4.8 (a) Histograms of pull-off force values obtained with an unmodified Si3N4 tip on untreated and oxyfluorinated iPP films in ethanol. The total surface free energy y of the polymer film is shown, (b) Mean values of pull-off force measured with COOH-terminated tips on modified polyolefin surfaces (iPP, isotactic polypropylene LDPE, low-density polyethylene) in ethanol (top) and with OH-terminated tips on oxyfluorinated iPP in water (pH 3.8, bottom) as a function of cos 0 (contact angle measured with water).

Pig. 1. Typical microhardness values of pol3maers compared with data for metals. LDPE, low density polyethylene HDPE, high density polyethylene iPP, isotactic polypropylene CEPE, chain-extended polyethylene POM, polyoxymethylene aPS, atactic polystyrene PET, poly(ethylene terephthalate) PEN, pol3Kethylene naphthalene-2,6-dicarboxylate) CF composite, carbon-fiber composite. Hardness data of metals and alloys markedly depend on composition, degree of work-hardening, processing conditions, etc. For this reason, the values in Figure 1 should be considered as typical values rather than as absolute values. Most of the data for metals are taken from Ref 1. [Pg.3634]
