“…Polymer material in filler pores or in the gaps between filler particles will exhibit properties, such as the glass transition temperature, that are different from those of the polymer in an unconfined region. Nucleation tends to be suppressed in confined systems, including ultrathin films 109,114,115 and nanopores, 118,123 and is attributed to a reduction in chain mobility. 115,118 Effect of fillers on degree of crystallinity and spherulites While simulations have provided insight into how fillers may influence crystallisation, the picture from experimental studies is less Figure 6 Changes in crystallinity, Χ c , and spherulite size, S, for filled samples with filler weight percent compared to pure PHB.…”
