zkf- 中文意思是什麼

This dissertation focuses on how to develop a high performance damping mechanism based on multi - energy transitions, which is independent or little dependant with the viscoelasticity of polymer matrix. three sections are mainly included in this dissertation as follows : chlorinated polyethylene ( cpe ) / piezoelectric ceramic ( pzt ) / vapor grown carbon fiber ( vgcf ) composites ; cpe / 2, 2 ' - methylene - bis - ( 4 - methyl - 6 - cyclohexylphenol ) ( zkf ) / vgcf composites ; organic hybrids made from cpe and small molecules cpe / pzt / vgcf composites : the damping composites of multi - energy transitions mechanism were produced by mixing pzt and vgcf into cpe. in this system, the mechanical vibration energy that was transmitted to cpe was found to convert into joule ' s heat through conduction paths between vgcf in the polymer matrix, so the vibration fades away

本論文主要包括三個方面的研究內容： ?氯化聚乙烯（ cpe ） /壓電陶瓷（ pzt ） /氣相生長碳纖維（ vgcf ）復合材料； ? cpe /雙[ （ 2 -羥基- 3 -環己基- 5 -甲基） -苯基]甲烷（ zkf ） / vgcf復合材料； ? cpe基有機小分子混雜型復合材料cpe / pzt / vgcf減振復合材料：利用壓電和導電填料填充高聚物基體，當復合材料受到機械振動時，通過高聚物基體將機械振動能傳遞到壓電陶瓷粒子上，利用壓電陶瓷的壓電效應，將機械能轉換成電能，則電流在導電粒子產生的迴路中流動，由於導電迴路具有一定的電阻，所以電能又轉變成熱能耗散掉，從而起到減振的目的。

In this section, a small organic molecule is applied to instead of pzt with the purpose to avoid the rigidity difference between cpe and pzt. ( 1 ) there is no plateau area in the conductivity curve of cpe / pzt / vgcf composite, which is due to the molecular level blending of cpe and zkf in molten condition during the preparation of cpe / zkf / vgcf composites, further verifying that pzt is conducive to the formation of conductive loop

通過對cpe / zkf / vgcf復合材料的分析探討得出: （ 1 ） cpe / zkf腳gcf復合材料的導電曲線上並不存在類似cpe / pzt渾gcf復合材料的半導區平臺，這是由於cpe億kf / vgcf復合材料的制備是在cpe和zkf熔融的狀態下的分子水平的共混，進一步證明了pzt對導電迴路形成的雙重作用;同時，由於zkf對vgcf的包覆作用，使cpe億kf那gcf復合材料導電臨界值較高。

( 4 ) only when the resistance r = l / c, the transition efficiency between electric energy and heat reach its maximum value, which makes it possible to design the high performance damping composites of multi - energy transitions by adjusting the vgcf content. cpe / zkf / vgcf composites : in the cpe / pzt / vgcf composites, the conversion efficiency from force to electricity is very low because of the obvious difference of rigidity between cpe and pzt, which leads to the damping effect of multi - energy transitions is not so evident as the viscoelasticity of the matrix cpe, especially during the cpe glass transition

Cpe / zkf那gcf復合材料:針對cpe / pzt / vgcf復合材料中由於cpe和pzt之間模量差異較大，導致cpe和pzt之間的應力傳遞欠佳，影響力一電變換效率，從而壓電導電減振作用效果並不十分顯著的現象;本章中採用極性有機小分子雙（ 2一輕基- 3一環己基一5一甲基）一苯基]甲烷（ zkf ） ，而不採用pzt ，消除了pzt與cpe模量方面差異的影響。
