Skim and cream natural rubber particles: colloidal properties, coalescence and film formation.

摘要: Abstract Cream and skim fractions of freshly tapped natural rubber latex have been studied using atomic force microscopy scanning electric potential to elucidate the topology charge properties in film formation. Elemental distribution maps particles also obtained electron energy-loss imaging a low-energy transmission microscope. The two are by centrifugation. cream fraction is stable while rapid coagulation occurs fraction. After removal coagulum, no further remaining stable. from contain higher amount adsorbed protein–phospholipid materials compared those “self-cleaned” This difference membrane property has significant impact on spreading cis -1,4-polyisoprene cores, their coalescence formation behavior. Coalescence appears be hindered materials, forming rough that retains individual particles. Skim coalesce more readily, relatively smooth films.
