西方中心主义是实践发展与历史文化结合的产物,该观点强调西方文明的先进性,试图以资本主义文化为标准去衡量和改造各类文化。罗尔斯作为当代最为著名的政治哲学家之一,其有关正义理论的论述对当代政治哲学产生了深远影响。尽管如此,罗尔斯对国际正义理论的论证在话语体系和观点表达上潜在地遵循了西方中心主义的逻辑,在万民社会的划定、万民法的证成以及非理想状况的解决中都始终体现着西方中心主义的立场。因此,罗尔斯的国际正义理论不仅存在着诸多逻辑漏洞,还为西方社会的国际特权与国际霸权提供了辩护。鉴于此,当前的国际正义理论亟需在打破西方中心主义的话语体系的基础上进行重构,结合关系平等、行为判断、动态分析三个维度的内容可以有效增强国际正义理论的可信度与可行性。

以约翰·罗尔斯、罗纳德·德沃金为代表的资源主义平等分析路径和以功利主义者为代表的福利主义平等分析路径长期占据平等理论的中心地位,阿玛蒂亚·森的可行能力平等理论为平等理论提供了新的思考路径,并引起了大量的关注和讨论。G.A.柯亨肯定了森对资源平等和福利平等的批判,但对森的可行能力概念及其平等理论的证成提出了质疑。柯亨主要围绕可行能力平等理论的模糊性问题以及可行能力是否涵盖了基本善与效用之间的维度进行了论述,并提出“中间福利”来替代可行能力概念,以支持自己的“可获得利益”平等理论。实际上,G.A.柯亨在一定程度上误解了森的可行能力概念,森的可行能力平等理论能够同柯亨所说的中间福利相区分,只要仔细对比,就可以否定柯亨的观点。但这并不代表森的可行能力平等理论是完全合理的,在列举能力清单、判断能力重要性以及理论的可行性方面,森还需要做出详细的解释和论证。

Multifunctional organically modified graphene with super-hydrophobicity

引用

Nano Research 2014年第3期7卷 418-433页

作者： Huawen Hu Chan C. K. Allan Jianhua Li Yeeyee Kong Xiaowen Wang john H. xin Hong Hu Institute of Textiles and Clothing The Hong Kong Polytechnic University Hong Kong Special Administrative Region (SAR) 999077 China

In order to bring graphene materials much closer to real world applications, it is imperative to have simple, efficient and eco-friendly ways to produce processable graphene derivatives. In this study, a hydrophilic low-temperature thermally functionalized graphene and its super-hydrophobic organically modified graphene derivative were fabricated. A unique structural topology was found and some of the oxygen functionalities were retained on the thermally functionalized graphene surfaces, which facilitated the subsequent highly effective organic modification reaction and led to the super-hydrophobic organically modified graphene with multi functional applications in liquid marbles and polymer nanocomposites. The organic modification reaction also restored the graphenic conjugated structure of the thermally functionalized graphene, particularly for organic modifiers having longer alkyl chains, as confirmed by various characteri- zation techniques such as electrical conductivity measurements, ultraviolet/visible spectroscopy and selected area electron diffraction. The free-standing soft liquid marble was fabricated by wrapping a water droplet with the super-hydrophobic organically modified graphene, and showed potential for use as a microreactor. As for the polymer nanocomposites, a strong interfacial adhesion is believed to exist between an organic polymer matrix and the modified graphene because of the organophilic coating formed on the graphene base, which resulted in large improvements in the thermal and mechanical properties of the polymer nanocomposites with the modified graphene, even at very low loading levels. A new avenue has therefore been opened up for large-scale production of processable graphene derivatives with various practicable applications.
