The stress-strain curve, optical orientation factor, refractive indices, refractive index profiles, orientation angle, Young's modulus, elastic shear modulus and compressibility were investigated for the PGA/PCL suture materials at different draw ratios. The behavior of the stress-strain curve of PGA/...
摘要:采用二步共混法制备改性聚己二酸/对苯二甲酸丁二酯/聚乙醇酸 (PBAT/PGA)共混物,其中,添加多元环氧化合物 (ADR)为扩链剂和反应增容剂。首先通过第一步高温熔融共混 (235℃),制备得到PBAT/PGA二元预混物;随后添加ADR进行低温共混 (170℃),最终得到...
研究结果表明,随着ADR的加入,PGA/TPEE/ADR共混物的黏度和熔体强度上升、加工成型稳定性得到较大改善。当ADR添加量增大至0.9份时,PGA/TPEE/ADR(75/25/0.9)共混物的MFR值由PGA/TPEE (75/25)共混物的32.5 g/10 min降低至13.2 g/10 min。此外,ADR作为反...
