| 英文摘要 | fully biodegradable polymer blends based on biosourced polymers, namely poly(l-lactide) (plla) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (p(3hb-co-4hb)) are prepared by melt compounding. the enzymatic degradation and porous morphology of plla/p(3hb-co-4hb) blends are investigated in detail. the lipase from pseudomonas mendocina reveals preferred enzymatic degradation of p(3hb-co-4hb) but insignificant attack to plla in the blends. at the same time, proteinase k can degrade plla, but cannot degrade p(3hb-co-4hb). on account of the surface erosion mechanisms, the enzymatic degradation rates of both the p(3hb-co-4hb) and plla in the blends are improved because of the presence of the other component to increase the specific surface area. the results of the h-1 nmr and gpc indicate that there is no more intermediate products formed during the enzymatic degradation of the plla and p(3hb-co-4hb). due to the specificity of the degradation enzymes, selective enzymatic degradation is adopted to degrade and remove one component from the blends, and various porous morphologies are acquired. |
