Method for fast filling of templates for imprint lithography using on template dispense

McMackin et al of Molecular Imprints has developed a method for filling a recess of a patterned substrate for use in imprint lithography.  The filling time is reduced by applying a vacuum or a fluid jet and removing excess liquid.  (RDC 1/7/2010)

 Polyamide capsules via soft templating with oil drops—2. Subsequent radical polymerization of styrene
(121-132)
Colloid and Polymer Science 289 #2 (2011)
Essawy and Tauer, Germany and Eygpt produced composite polyamide–polystyrene microcapsules by successive polycondensation and radical polymerization a one-pot multi-step reaction.  The first step is the emulsification of the template oil phase that contains terephthaloylchloride, styrene monomer, if necessary a cyclohexane–chloroform mixture, and the oil-soluble radical initiator in an aqueous poly(vinyl alcohol) solution. The morphology of the composite capsules depends strongly on the amount of styrene monomer in the oil mixture and the nature of the initiator.  (RDC 2/14/2011)

 

001[2011]  Sacrificial functional polystyrene core template to fabricate cross-linked chitosan nanocapsules
e-Polymers(2/14/2011) (5)
[Abstract]
Liu and Xu prepared biocompatible and biodegradable chitosan microcapsules using carboxyl-functionalized polystyrene (PS) particles as core template and the chitosan cross-linked with gultaraldehyde as the shell. Firstly, the monodisperse functionalized PS particles are made by emulsifier-free emulsion polymerization. Secondly, microcapsules are formed on the basis of chemical cross-linking on the surface of the carboxyl-functionalized PS particles and by removing the core template. The latex particles are removed by  solvent leaving hollow  microcapsules.  (RDC 2/14/2011)

Interplay of kinetics and interfacial interactions in breath figure templating – A phenomenological interpretation
(2337-2344)  Polymer 51 #11 (2010)
Servo et al of the University of Trento, Italy used Breath Figure BF templating foe producing porous films.  This templating is based on the exposure to a moist airflow, monodisperse water droplets condensing on the surface of evaporating polymer solution into ordered arrays.  These droplet become a template for the final film structure.  Studies with polylactic acid films show the interfacial forces govern the physical interactions among water, solvent and polymer, but the dynamics of the process and thus the final pore structure is regulated by kinetics.  (RDC 12/22/2010)

Template-assisted assembly of electrospun fibers 
(3244-3248) Polymer 51 #14 (2010)
Wu et al of the University of Rochester, New York  used patterned collectors to produce aligned membranes with designed topological structures.  The template-assisted electrospinning approach is demonstrated using polycaprolactone (PCL) fibers to produce patterns including alphanumeric characters and a printed electronic circuit chip, with feature sizes on the order of several hundred microns.  The process has a significant impact on micro-manufacturing, and provides the capability for incorporation of oriented fiber materials in patterned micro-composites and electronic components.  (RDC 12/22/2010)

Janus composite nanorings by combinational template synthesis and skiving micro-process  
( 3606-3611) Polymer 51 #16 (2010)
Zhou et al of the Institute of Chemistry, China fabrication Janus composite nanorings by skiving the corresponding arrayed nanotubes.   The polymer nanotubes and their arrays are polymerized from the pore surface via ATRP inside porous anodic aluminium oxide membrane (AAO) templates.  As examples, Janus composite nanorings of sulfonated PS/PS, titania/PS, silica/PS and PANi/PS are prepared.  (RDC 12/22/2010)
