20世纪80年代以来,随着一系列现代性风险的凸现,对现代性与发展之间关系的反思与追问成为理论界的关注热点。中国正处于社会转型期,改革开放30多年来呈现出一系列现代性风险景象。国内外风险并生,传统式与现代型风险共存,结构性风险和过程风险并存,呈现多元复合的特点。转型风险是发展过程中的风险,这就要求从调整社会发展方式出发来超越发展的悖论、化解当代风险问题。建立在现实批判基础上的马克思主义发展观正是解决发展悖论的理性选择。科学发展观是当代中国的马克思主义发展观,强调以人为本,全面、协调、可持续发展,人与自然和谐相处,是当代中国破解现代性风险的有效途径。

采用近场静电纺丝法制备了P(VDF-TrFE)(聚偏氟乙烯PVDF和三氟乙烯TrFE的共聚物)压电纤维,研究了不同的电纺工艺参数对纤维直径和形貌的影响。结果表明,近场静电纺丝法的工艺参数对纤维形貌特征有决定性影响。其中,P(VDF-TrFE)电纺溶液的质量浓度对纤维的形成起决定性因素,当P(VDF-TrFE)电纺溶液质量比小于12%时,液滴下落过程中溶液中的溶剂挥发速度不够,导致电纺工作时溶液沉积到衬底前无法呈纤维状;在合适的驱动电压范围内,施加的电压越大,纤维直径越细;同样,采集器的移动速度越快,纤维的直径越细;电纺获得的P(VDF-TrFE)纤维直径可达(0.7~12)μm。此外,根据P(VDF-TrFE)自身的压电特性,给以纤维一定的弯曲形变,测试了电纺丝法制备的P(VDF-TrFE)纤维是否产生极化。实验结果表明,原位制备的纤维未能表现出明显的压电性。
