The mechanical properties of PBS such as softness and flexibility are insufficient for various end-use applications. For desirable mechanical properties, fillers are mixed into the biodegradable polymer matrix. Also, the prices of these biodegradable PBS are generally high cost and thus blending with low-price resins becomes an alternative approach to resolving this problem. In particular, biopolymer fillers derived from annually renewable resources and used to form biodegradable blends have received much attention recently. Starch, one of most abundant natural food sources for most plants, has been considered an attractive biopolymer filler because of its low cost, low density, nonabrasive nature, biodegradability, "$(*0268<>@NǺ}}}}jM9h$h>B*CJKHOJPJQJ^JaJnHphtH$h$h>CJKHPJaJnHtH-h>h>B*CJKHOJQJ^JaJph*h>B*CJKHOJQJ^JaJo(phh>h>CJOJQJ^Jo(h>CJOJQJ^Jo(h>h>CJo( h>CJo(hM4CJPJnHo(tHh7CJPJnHo(tHh?=CCJPJnHo(tH$*28>$d$1$G$Ifa$gd9 dh`gd>@&gdNaXnX>@`jx~\BBBB$d8$1$G$If]^a$gd9kd$$If|\K@"g       t0624aNP^`hjvx|~ħzzdM:ħzdM:$h$h>CJKHPJaJnHtH-h`-h>B*CJKHOJQJ^JaJph*h`-B*CJKHOJQJ^JaJo(ph-h>h>B*CJKHOJQJ^JaJph*h>B*CJKHOJQJ^JaJo(ph9h$h>B*CJKHOJPJQJ^JaJnHphtH9h$h>B*CJKHOJPJQJ^JaJnHphtH<h$h>B*CJKHOJPJQJ^JaJnHo(phtH~\BBBB$d8$1$G$If]^a$gd9kd<$$If|\K@"g    t0624a\BBBB$d8$1$G$If]^a$gd9kdx$$If|\K@"g    t0624a  ħzdM:- h`-CJOJQJ^Jo(h>CJOJQJ^Jo($h$h>CJKHPJaJnHtH-h`-h>B*CJKHOJQJ^JaJph*h`-B*CJKHOJQJ^JaJo(ph-h>h>B*CJKHOJQJ^JaJph*h>B*CJKHOJQJ^JaJo(ph9h$h>B*CJKHOJPJQJ^JaJnHphtH9h$h>B*CJKHOJPJQJ^JaJnHphtH<h$h>B*CJKHOJPJQJ^JaJnHo(phtH    \P>>>$d$1$G$Ifa$gd9 dh`gd>kd$$If|\K@"g    t0624a      " 4 6 8 : > T V ` b d n r ̵̵̵h̅O8-h`-h`-B*CJKHOJQJ^JaJph0h`-h`-B*CJKHOJQJ^JaJo(ph9h$h`-B*CJKHOJPJQJ^JaJnHphtH9h$h`-B*CJKHOJPJQJ^JaJnHphtH$h$h`-CJKHPJaJnHtH-h`-h`-B*CJKHOJQJ^JaJph*h`-B*CJKHOJQJ^JaJo(phh>h>CJOJQJ^Jo(h>CJOJQJ^Jo( " 6 V b oUCC$d$1$G$Ifa$gd9$d8$1$G$If]^a$gd9kd$$IfF.     t06    24ab d t o]]C$d8$1$G$If]^a$gd9$d$1$G$Ifa$gd9kd$$IfF.    t06    24ar t     . 0 6 8 : < ѺѺmъѺmTTѺM h>CJo(1h$h`-B*CJKHOJPJQJ^JaJph9h$h`-B*CJKHOJPJQJ^JaJnHphtH9h$h`-B*CJKHOJPJQJ^JaJnHphtH$h$h`-CJKHPJaJnHtH-h`-h`-B*CJKHOJQJ^JaJph*h`-B*CJKHOJQJ^JaJo(ph0h`-h`-B*CJKHOJQJ^JaJo(ph o]N]$$1$G$Ifa$gd9$d$1$G$Ifa$gd9kd$$IfF.    t06    24a  0 8 o]N]$$1$G$Ifa$gd9$d$1$G$Ifa$gd9kd$$IfF.    t06    24a8 : < > D h oii`NHdh$IfWD`Hgd/m# $Ifgde@&gdNkd $$IfF.    t06    24a< > B D J N V X Z ^ f h j n p ˾{uhV8;h/m#h/m#B*CJKHOJPJQJ\aJnHo(phtH#h/m#h/m#CJOJPJQJaJo(hJ[CJOJQJaJo( hNCJ hNCJo('hZhM4CJOJPJQJnHo(tH'hZh/m#CJOJPJQJnHo(tH'hZh7CJOJPJQJnHo(tHh7CJPJnHo(tHh/m#CJPJnHo(tHhJ[hN5OJQJ\o(hJ[5OJQJ\^Jo(h>h>CJo(h j p  F ~lll<dh$IfWD`<gd/m# $Ifgdexkd" $$Ifl40 (`  0(64 laf4      , . : > @ D F H P R x ɯugXE%hf/cCJOJPJQJ^JnHo(tHhJ[hN5OJQJ\o(hJ[5OJQJ\^Jo(hNCJnHtH'h/m#hNCJOJPJQJnHo(tH7h/m#h/m#B*KHOJPJQJ\aJnHo(phtH3h/m#hZB*CJKHOJPJQJ\aJo(ph;h/m#h/m#B*CJKHOJPJQJ\aJnHo(phtH0h/m#hZB*CJKHOJPJQJ\aJphF H R | ~r dh$Ifgdf/c $Ifgdexkd $$Ifl40 (`  0(64 laf4x z | ~      " ʻʣzthWF4#h=hICJOJPJQJaJo( h.K]5CJOJQJ^JaJo(!hJ[hN5OJQJ\^Jo(hJ[5OJQJ\o( hNCJ+hf/chNCJOJPJQJ^JnHo(tH%hf/cCJOJPJQJ^JnHo(tH/hf/chf/cCJOJPJQJ^JaJnHo(tHhJ[hN5OJQJ\o(h2hN5OJQJ\o(h}hNCJh}hNCJo(%hzCJOJPJQJ^JnHo(tH| ~ ~~rf dh$Ifgdf/c dh$Ifgde $Ifgdexkdl $$Ifl40 (`  0(64 laf4    , . qr~rffffffff d$IfgdI d$Ifgd.K] $Ifgdexkd $$Ifl4F0 (`  0(64 laf4 "  " * , . 2 ?Av}~?Aipqrt U]^` <>[˼ݩII3333+h>h>CJOJPJQJaJnHo(tH%h=CJOJPJQJaJnHo(tHh=CJOJPJQJaJo(#h=hNCJOJPJQJaJo(#h=hICJOJPJQJaJo( h=hICJOJPJQJaJ:^cofT$d$1$G$Ifa$gdI $Ifgdexkd $$Ifl40 (`  0(64 laf4 d$Ifgd> d$IfgdI [bcfzȷȷ𡛍pY=7hZh.K]B*CJKHOJPJQJ\nHo(phtH,hI5B*CJKHPJ \nHo(phtHhJ[hN5OJQJ\o(hJ[5OJQJ\^Jo(h5OJQJ\^Jo( hNCJ+h>hICJOJPJQJaJnHo(tH h=hICJOJPJQJaJ#h=hICJOJPJQJaJo(+h>h>CJOJPJQJaJnHo(tHh=CJOJPJQJaJo(ɭɭzl^O>+$hZh.K]CJOJPJQJ^JaJ h.K]5CJOJQJ^JaJo(hJ[hN5OJQJ\o(hJ[5OJQJ\^Jo(h5OJQJ\^Jo( hNCJ+hJ[hNB*CJKHOJQJ\o(ph,hZh.K]B*CJKHOJPJQJ\ph7hZh.K]B*CJKHOJPJQJ\nHo(phtH7hZhIB*CJKHOJPJQJ\nHo(phtH4hZhIB*CJKHOJPJQJ\nHphtH U^XcZNNN d$Ifgd.K] $IfgdexkdI $$Ifl4u0 (`  0(64 laf4$d$1$G$Ifa$gdJ[$d$1$G$Ifa$gdIJTUUU]X^X_X`XaXbXdXeXgXhXjXkXnXoXسhjhU hw~o(hq0hNCJh.K]h.K]5OJQJ^Jo('hZhNCJOJPJQJ^JaJo(hZh.K]OJPJQJ^JU$hZh.K]CJOJPJQJ^JaJ'hZh.K]CJOJPJQJ^JaJo(and so forth. Unfortunately, native starch generally exists in a granular state because of the inherent hydrogen bonding between adjacent molecules. Therefore, starch fails to disperse on an extremely fine scale into a plastic matrix. Efforts to solve this problem have led to the recent development of thermoplastic starch prepared by the incorporation of suitable amounts of water and plasticizers; this is called gelatinization. This work was undertaken to examine in depth the effect of starch and gelatinized starch on the physical and mechanical properties of PBS/starch blends. Different degrees of gelatinization were used with various amounts of glycerol. The blends were characterized with thermal analysis, including differential scanning calorimetry (DSC) and Thermogravimetric analysis(TGA). The tensile strength and elongation at break were evaluated and elucidated in a morphology study with scanning electron microscopy(SEM). In summary, this study could lead to a better understanding of blend performance and pave the way to producing a new generation of biodegradable plastics for our environment.      ^X_X`XaXcXdXfXgXiXjXlXmXnX{vqoqoqoqoogdzgd<xkd $$Ifl4l0 (`  0(64 laf4 d$Ifgd.K] nXoXgd<:&P 182P:p>.
