摘要

采用热致相分离法(TIPS)制备了含有不同比例邻苯二甲酸二辛酯(DOP)和邻苯二甲酸二丁酯(DBP)混合稀释剂的聚(4-甲基-1-戊烯)(PMP)多孔膜。研究了混合稀释剂比例对PMP相分离形态、结晶性、流变性和萃取后多孔膜结构和性能的影响。结果表明：在相容性较好的DOP中引入相容性较差的DBP，体系结晶温度降低，细化PMP尺寸，相分离形态由固液相分离向液液相分离转变。DBP的引入有助于降低熔体黏度，缩短松弛时间，提高PMP熔体在大应变条件下的稳定性。当DOP和DBP的质量比为3:7时，多孔膜有最大的氧气透过率，达到8.2 mL·min

Abstract

Using the thermally induced phase separation (TIPS) method

poly(4-methyl-1-pentene) (PMP) porous membranes were prepared using various ratios of dioctyl phthalate (DOP) to dibutyl phthalate (DBP) mixed diluents. This study investigated the effects of mixed diluent ratios on the phase separation morphology

crystallinity

rheological properties

structure

and performance of porous membranes after extraction. The results indicated that introducing the less compatible DBP into the more compatible DOP reduced the crystallization temperature and refined the PMP dimensions

shifting the phase separation morphology from solid-liquid phase separation to liquid-liquid phase separation. The addition of DBP contributed to a reduction in melt viscosity

shortened relaxation time

and improved the stability of the PMP melt under large strain conditions. When the mass ratio of DOP to DBP was 3:7

the porous membrane exhibited the highest oxygen permeability (8.2 mL·min

with a tensile strength of 5.8 MPa and tensile modulus of 180 MPa.
