试论知识产权与企业自主创新

没有自主创新，就谈不上自主知识产权。技术创新是企业获得专利的重要前提，技术创新过程本身也是一个获得专利等自主知识产权的过程；从专利制度赋予企业的专利保护和激励发明创造的功能，以及由此给企业创造的巨大利益。不难看出知识产权制度是企业自主创新的重要动力之一：知识产权制度的核心是保护知识产权不受侵犯．因而企业不会因为技术创新成果申请专利后，被他人擅自仿造，从而有利于营造企业公平竞争的环境；新技术的商品化和产业化，是技术创新的根本目的。专利制度把保护和鼓励技术发明的商品化作为根本出发点，调动了科技人员将其技术创新成果市场化的积极性：专利制度鼓励发明创造尽早公开。在公开的情况下对发明创造进行法律保护，企业完全可以在最大限度降低创新成本的前提下，充分利用和合理配置研究与开发的资金、人力和设备等创新资源。

原位合成纳米羟基磷灰石/葡甘聚糖复合材料流变特性研究

采用原位合成法制备HA/KGM溶胶,应用单因素实验方法研究KGM质量分数、温度、pH值对复合溶胶黏度的影响.结果表明,HA/KGM溶胶黏度随KGM质量分数、pH值增加而递增,随温度上升而下降,但过高质量分数和pH值时溶胶转变成凝胶,黏度急剧下降.较高pH值和较高的质量分数不利于形成均匀的HA/KGM复合溶胶.此结果可为HA/KGM复合材料进一步研究提供参考.

The Effect of Casting Solvent on the Electrical Property of Polyaniline/ Polyacrylonitrile

Blends of dodecylbenzene sulfonic acid doped polyaniline （PANI-DBSA） and polyacryionitrile （PAN） dissolved in either CHCh/DMF or CHCl3/DMSO mixture were solution cast. The conductivity of the blends with various compositions was measured and the doped ：xtent of PANI- DBSA in different casting solvent systems was studied. Solution blends prepared from CHCh/DMSO displayed higher conductivity than those obtained via CHCh/DMF. The dedoping reaction of PANI-DBSA in CHCl3/DMF identified by UV-Vis and FTIR analysis contributed to the lower conductivity of PANI-DBSA/PAN blend.

Research on Flax Fiber Reinforced Polylactide Environmental Friendly Composite

Biodegradable polylactide acid （PLA） resin can be combined with flax fibers to produce biodegradable composite materials. In our study, commercial PLA fibers were mixed with flax fibers by a non-woven method so as to make non- woven pre-forms, which can be generated into flax fiber reinforced PLA environmental friendly composites by heat pressing technology. The tensile, flexural and impact properties are tested in order to evaluate the basic physical properties of the composites, and the influenced factors listed as making technology of the pre-forms, weight ratio of flax fibers and heat pressing technology are discussed and optimized, which can be described as weight ratio of flax fibers and PLA fibers is 50/50, heating temperature, time and pressure are respectively 195℃, 20 rain and 12.5 Mpa. Preliminary results show that mechanical properties of the flax/PLA composites are quite promising compared with flax/PP composites in coclrnon commercial automotive use. Scanning electron microscope （SEM） is used to analyze the tensile specimen fracture surfaces, which shows voids and gaps occurring between flax fibers and PLA matrix and sign of fiber pull.out, the strength of flax/PLA interface can be further improved.
