【文章內(nèi)容簡介】 heological characterization2 Fig. 4. Mechanical spectra of Pol1 at 25 176。C (A) and 43 176。C (B). Results are the means of three measurements. SD was always lower than 10% G ′及黏性模數(shù) G 〞 在 25℃ 及 43℃ 剪切頻率~1的範(fàn)圍下， Pol1會(huì)產(chǎn)生什麼樣的變化，由 Pol1的成膠溫度為 37 ℃ ，由 (A)可看出在 25 ℃ 、剪切頻率 ~1的條件下 ， G 〞 ＞ G ′，由此篇文章定義來說這是未成膠的狀態(tài) ，而在 43 ℃ 、剪切頻率 ~1的條件下， G 〞 ＜ G ′，文章定義此為成膠狀態(tài) ，此結(jié)果呼應(yīng)了前面 Pol1在過了 37 ℃ 後會(huì)是成膠的狀態(tài)。 Rheological characterization3 Fig. 5. Elastic modulus as a function of frequency of Pol1 containing different amount of HA at 43 ℃ . Results are the mean of three measurements. SD was always lower than 10%. Error bars are omitted for clarity purpose. Photon correlation spectroscopy Table 2 Hydrodynamic diameters, elastic and viscous moduli values (at Hz and 43 ℃ ) of Pol1 containing %, %, 1% and 2% w/w of HA Results are the means of three measurements. SD was always lower than 10%. G ′、黏性模數(shù) G 〞 和流體動(dòng)力學(xué)直徑 (HD)的大小，由大而小分別是 Pol1/H Pol1/H Pol1/H0 Pol1/H0 Pol1，由此數(shù)據(jù)來決定 Pol1/H2具有較佳的生物黏附性。 Mucoadhesion analysis1 Fig. 6.
