摘要

由於自然環境之改變，都市叢林、森林樹木減少，河川變淺，溪流加蓋，現代人的居住環境中之負離子已大數量減少，再說因為大量的空氣污染、室內的電器產品、3C設備、空調設備等，致使正離子大量產生，正離子甚至嚴重威脅到現代人之健康，加上生活壓力及食、衣、住、行方面的習慣，文明病因此而產生，有鑑於此，本論文採用能釋放出負離子功能之次微米粉末與機械性質較佳的高分子當作基材施以掺混處理，並經由射出成型機射出成型，以製備出能在空氣中釋放出負離子、吸臭性與清淨環境的永久型複合材料。
在本論文中以有機高分子/負離子複合材料為原料，改變風扇之風量、負離子粉末之含量、測試樣本片數及測試樣本與負離子感測器間的距離等參數，以探討負離子樣本與空氣間之磨擦所釋放出每立方公分負離子之個數。除此之外，尚針對其他有利於人體之效能來做出多功能之複合材料。例如功能性方面，選用中底鞋墊材料-乙烯-醋酸乙烯酯共聚物(EVA)來作為複合材料之基材，可應用在鞋子中底鞋墊上，讓鞋墊對人體腳底產生負離子或是蓄熱保溫以及吸臭之功能；在實用性方面，本論文採用機械性質較佳之聚丙烯(PP)來作為負離子複合材料之基材，並藉由複合材料所釋放出負離子功能，應用在冷氣機出風口(汽車用)之葉片、風扇葉片，利用出風口之風量與負離子複合材料葉片間之摩擦來釋放出負離子之效果。
經由實驗結果顯示隨著風扇之風量、負離子粉末之含量、測試樣本片數之增加所釋放出每立方公分負離子之個數有逐漸增加之趨勢，本論文之PP/N、PP/J負離子複合材料其所釋放之負離子個數可達1000個/cm3以上，已經可以達到人體維持基本建康之需求。

Due to the change of natural environment such as the presence of tall buildings all over in the city, the shrinking forests, the shallowness of rivers and creeks and the reduced covering of brooks, the quantity of NI in the modern living environment has already been greatly reduced. Moreover, heavy air pollution and the frequent use of indoor electric equipment, computer, communication, and control equipment, air conditioning, etc., produce positively charged cations in large amounts that can seriously threaten modern people’s health. In addition, due to the pressure for living and some individual bad habits, cations could be the cause of the so-called “disease of civilization” that has become more common recently. In view of this, selected sub-micron powders with the ability of releasing NI and polymers with better mechanical properties are adopted in this research. The polymers as a matrix were evenly blended with powder first, then shaped by injection molding to obtain the permanent composites which can release NIs that are capable of absorbing stinks and also cleaning the air.
Organic Polymer/NI composites were used in this paper to investigate NI numbers per cubic centimeter that are released via the friction between air and the composites. The parameters for investigation include the fan flow rate, the NI powder content of specimens, the quantities of specimens, and the distance between specimen and NI sensor. The Negative-Ion Automatic Measuring System (NIAMS) was used to do the measurements. In addition, more multi-functional composites were produced that were beneficial to the human body. In a functional respect, while the Ethylene Vinyl Acetate (EVA) was selected as the matrix, it could be applied to the bottom shoe-pad that would have the function of producing NI so as to keep the foot warm and also absorbing any stink from shoes. In practicable respects, this research adopted polypropylene (PP) that has better mechanical properties as the matrix. It was applied to make blades for air conditioners (used in automobiles) and fans. Due to the friction between NI composite blades and the air, NI is released.
It has been shown that the NI numbers per cubic centimeter increased by increasing the flow rate of the fan, NI powder content, and specimen quantities. However, it decreased by increasing the testing distance between the specimen and the NI sensor. The PP/N and PP/J composites could release over 1000 NI per cubic centimeter, which already meets the requirements for a healthy body.
