报道了一类新型聚乳酸-共甘油酯单硬脂酸酯(PLA-PGC18)共聚物的合成及其作为生物可降解聚合物掺杂剂的应用,以提高聚乳酸-共乙醇酸(PLGA)非织造网的疏水性。将PLA-PGC18掺杂到PLGA溶液中,并通过静电纺丝形成微米尺寸的纤维网。纤维直径、掺杂百分比和共聚物组成影响网的非润湿性,并改变其机械(拉伸)性能。30%的聚合物掺杂可获得高达160°的接触角。最后,根据NIH/3T3细胞生物相容性测定,这些网状物是无毒的,并且在植入小鼠体内时显示出最小的异物反应。总之,构建具有可调疏水性的可生物降解纤维网的一般方法被描述用于组织工程和药物输送应用。
The synthesis of a family of new poly(lactic acid-co-glycerol monostearate) (PLA–PGC18) copolymers and their use as biodegradable polymer dopants is reported to enhance the hydrophobicity of poly(lactic acid-co-glycolic acid) (PLGA) nonwoven meshes. Solutions of PLGA are doped with PLA–PGC18 and electrospun to form meshes with micrometer-sized fibers. Fiber diameter, percent doping, and copolymer composition influence the nonwetting nature of the meshes and alter their mechanical (tensile) properties. Contact angles as high as 160° are obtained with 30% polymer dopant. Lastly, these meshes are nontoxic, as determined by an NIH/3T3 cell biocompatibility assay, and displayed a minimal foreign body response when implanted in mice. In summary, a general method for constructing biodegradable fibrous meshes with tunable hydrophobicity is described for use in tissue engineering and drug delivery applications.
