Surface Modification of Polypropylene Nonwoven after Plasma Activation at Atmospheric Pressure
polypropylene nonwovens ambient air plasma plasma activation
2009/2/16
Polypropylene non-woven fabrics were activated by an atmospheric-pressure plasma treatment in ambient air using a novel plasma source. Subsequently, the plasma activated samples were coated by a nanos...
Crystallisation of isotactic polypropylene with b-nucleating agents under elevated pressure
isotactic polypropylene polymorphism pressure
2009/2/6
Samples of isotactic polypropylene with b-nucleants (triphenodithiazine and E3B) were melted betweena cover slip and a glass slide on a microscopic hot stage, after which pressure was applied bymeans ...
Metastability in polymer systems studied under extreme conditions:high pressure, scan-iso T-t ramps and high scanning rates
calorimetry crystallisation DSC High Performance DSC high rate DSC
2009/2/6
Laboratory measurements on polymer raw materials and products are often carried out (quasi-)
isothermally, or at best at relatively slow cooling and heating rates. Such conditions differ greatlyfrom ...
