폴리아크릴로니트릴을 NaOH로 가수분해시키면 carboxylate anion과 carboxamide기가 생성되며, 물을 흡수할 경우 sodium carboxylate기의 해리로 팽윤이 크게 일어나므로 고흡수성을 지니게 된다[l]. 일반적으로 섬유가 팽윤을 하면 수축하며, 가수분해된 폴리아크릴로니트릴 섬유는 흡수되는 물 속의 염의 농도 또는 pH에 따라 팽윤도가 다르기 때문에 가수분해된 시간과 pH조건 변화에 따라서 수축하는 정도가 다르다. 과거의 연구결과에 의하면 아크릴 섬유는 2M HCI에서 최소의 길이로 수축하며, 2M NaOH에서 최대의 길이가 나타난다고 하였다[2].

Polyacrylonitrile diagnostic membranes were prepared to measure blood glucose level of diabetics. Final absorbances at 680 nm through activated polyacrylonitrile membranes were measured at various concentration of glucose in plasma. The end-point results of K/S values obtained from the absorbances had a linear relationship toward the glucose concentration. The effect of temperature on the measurements of glucose concentration was studied. The stability of polyacrlonitrile diagnostic membranes was examined at RH 80%.

Polyacrylonitrile diagnostic membranes were prepared to make blood-glucose self-checking system for diabetics. After the prepared polyacrylonitrile membranes were stored at sereval different environments, final absorbances at 680 nm were measured at various concentration in blood. The mesured blood-glucose level did not show the big differences at the various storage temperatures. It was found that the blood-glucose level decreased a little bit compared to the standard value after $10{\sim}30$ hours at high humidities.

폴리아크릴로니트릴을 NaOH로 가수분해시키면 carboxylate anion과 carboxanlide기가 생성되며, 물을 흡수할 경우 sodium carboxylate기의 해리로 팽윤이 크게 일어나므로 고흡수성을 지니게 된다. 일찍이 flory[1]는 가교된 고분자 전해질이 고흡수성을 나타내는 겔을 형성할 것으로 예측한 바 있다. 이 가교 결합이 아크릴 섬유의 부분 가수분해에 대한 자료는 새로운 기능을 부여하면서 섬유의 물성을 어느 정도 유지하는데 요구되는 조건을 제시하게되므로 향후 아크릴 섬유의 개질에 활용될 수 있다.

Radiolysis of polyacrylonitrile(PAN) has been studied. Parameters for crosslinking and scission induced by gamma-ray irradiation were obtained by means of sol-gel partitioning method. G-value of crosslinking in PAN ($\bar{M}n=6{\times}10^5$) was 0.038 and the gel dose 21.6 Mrad. The effects of irradiation on the thermal degradation rate in PAN was also studied. No appreciable changes in thermal degradation rate observed up to 81.8 Mrad of irradiation dose.

Diagnostics membranes which were made of polyacrylonitrile were prepared for the measurements of blood glucose concentration. Final absorbances at 680nm through polyacrylonitrile diagnostic membranes were measured at various concentration of glucose in blood. It was found that the end-point results of varing absorbance values as time (K/S) had a linear relationship toward the blood glucose concentration. The effects of possible constituents in human blood on the glucose concentration measurements were examined. As a result, most of the chemicals did not affect seriously on the blood glucose measurements.
