中文摘要： 猪笼草叶笼因具有捕食昆虫功能而受到广泛研究，但叶笼滑移区对昆虫的减附机理未见明确定论，基于滑移区表面结构与功能仿生制备致灾农业昆虫捕集滑板的研究处于初始阶段。本项目对叶笼滑移区、昆虫附着系统的表面形貌进行观测分析，获取结构、性质等信息；设计建立昆虫微测力系统并用以量化表征滑移区对昆虫的减附功能；研究滑移区表面结构对昆虫附着系统的影响规律并建立模型，综合揭示双重二元结构相互影响下滑移区对附着系统的减附机理；依据滑移区对附着系统影响规律，通过模拟计算获取表面结构仿生构建的最佳设计参数和工艺参数，利用脱蜡铸造、微纳电火花加工与高压静电吸附等技术实现滑移区表面结构的仿生构建，并测试分析该表面结构的生物摩擦学特性。本项目的研究可以全面阐明滑移区的减附机制，获取滑移区表面结构的仿生构建方法，为用于致灾农业昆虫诱集治理方面的捕集滑板的制备提供新的有效途径。

英文摘要： Nepenthes pitchers beares the function of trapping insects and has attracted comprehensive researches, but the specific conclusion about anti-attachment mechanism of slippery zone in the pitchers has not been reported, and the studies of biomimetically creating slippery trapping agricultural pests plate based on surface structures and function of the slippery zone are still at preliminary stage. In this project, we will acquire the microstructures dimensions, surface characteristics and physical properties of the slippery zone and the insect attachment system via observing and analyzing their surface morphologies. The insect micro-force measurement system will be designed and established and used to quantitatively analyze the anti-attachment function of slippery zones. We will explore the influence disciplinarian of slippery surfaces on insect attachment system, and establish the theoretical models to completely and accurately reveal the anti-attachment mechanism based on the dual binary structures of the slippery zone and the attachment system. Based on the influence disciplinarian, the optimal design parameters and technology parameters will be acquired via simulating and calculating. The surfaces structures of slippery zones will be biomimetically established with the technologies of lost wax casting techniqu
