Rheological Properties of Gelatin Gels

open access: yesNippon kagaku zassi, 1962
ゼラチンの濃厚水溶液ゲルについて鎖式応力緩和計を用いて,応力緩和実験を行なった。分子量約2万のゼラチンの濃度20,25%のゲルについて約2°~250℃の温度範囲にわたり4時間までの緩和曲線を求めた。これらの曲線は3個のMaxwe11要素を並列にした6要素模型であらわすことができ,その最長緩和時間の温度依存性から求めた見かけの活性化エネルギーΔHは20,25%の場合にそれぞれ6.9,9.1kca1/mo1であった。ゼラチンゲルは熱可逆性ゲルであり,ΔHはこの場合ゲル弾性のもととなる3次元網状構造において,ゼラチン分子鎖相互を結合している2次結合に対応するものと考えられる。既報のより低濃度のゲルに関するデータも含めてのΔHについての考察から ...

Rheological Properties of Alginate Gel.

open access: yesNIPPON KAGAKU KAISHI, 1994
アルギソ酸はβ-1,4結合したbマンヌロン酸(以下Mと略す)とα-1,4結合したL-グルロン酸(以下Gと略す)から構成される酸性高分子多糖である.著者らはアルギン酸-酢酸水溶液系でゲルが形成されること,また,そのゲル化濃度はアルギン酸分子中のマンヌロン酸/グルロン酸比に影響されG成分に富んだアルギン酸がより低濃度でゲル化すること,さらに,その原因はG成分に富んだアルギソ酸の方が分子鎖が剛直であるためであることを明らかにした.他方,アルギン酸水溶液に適当な二価金属イオソを添加すると溶液がゲル化することはよく知られている.著者らは,アルギン酸水溶液をゲル化するに要する添加塩量がSrCl2 Ca2+>Mg2+の順で減少するためと ...

Normal force controlled rheology applied to agar gelation

open access: yes, 2016
A wide range of thermoreversible gels are prepared by cooling down to ambient temperature hot aqueous polymer solutions. During the sol-gel transition, such materials may experience a volume contraction which is traditionally overlooked as rheological ...
