“…15,16 Similarly, thickness and surface interactions of ultrathin polymer films (the film thickness is in the order of 2R g of a polymer chain, or less) highly influence their glass transition and melting temperatures, [17][18][19] polymer dynamics in the glassy state, 20 crystallization kinetics and degree of crystallinity, [21][22][23] phase behavior, 24 and morphology. 25,26 For all the above examples, the portion of ''surface material'' is comparable with the bulk, due to extremely small object size, therefore, the ansatz claiming ''nano-object ÂŒ bulk ĂŸ surface'' seems relevant for such systems from a physical point of view. However, in certain experimental systems, 27,28 the size-dependent behavior of nanofibers bearing considerably higher transversal size ($500 nm) refute the size-dependence ansatz and require additional expressions to explain their behavior.…”
