gradient copolymer
解釋
梯度共聚物-
In this paper, pan based metal gradient composites films ( pmgcf ) were prepared by electrochemical reduction. the effect of polymer matrix on pmgcf and preparation and its forming mechanism of pmgcf were invested, they are as follows : lacrylonitrile - methyl - methacrylate copolymer, acryonitrile - itaconic acid copolymer, acrylonitrile - methyl methacry late - sodium allyl sulfonate terpolymer have been synthesized seperately in order to analyze the effects of the mma monomer unites and the hydrophilic unites of acryonitrile terpolymer on the process of copper deposition in polyacrylonitrile - based metal gradient composite film ( pmgcf ) as well as the flexibility of the film
其內容如下： 1通過合成的丙烯腈?甲基丙烯酸甲酯二元共聚物（ p （ an - mma ） ） ，丙烯腈?亞甲基丁二酸二元共聚物（ p （ an - ita ） ） ，丙烯腈-甲基丙烯酸甲酯?丙烯磺酸鈉三元共聚物（ p （ an - mma - as ） ）分別作為基體制備了聚合物基金屬梯度復合膜材料（ pmgcf ） ，以分析加入的mma基團和親水性基團對pmgcf沉積層中金屬銅的梯度分佈形態和膜的柔韌性的影響。 -
3 the experiment showed that there is no copper deposition in the film using p ( an - mma ) as polymer matrix. but the copper deposition and gradient distributing appears in the film when using p ( an - ita ) and p ( an - mma - as ) as polymer matrix. the size and number of crystal increases as the concentration of ita in copolymer increase and the film is prone to be ruptured
3實驗顯示p （ an - mma ）作為基體制備的pmgcf五金屬沉積，銅的沉積量為零； p （ an - mma - as ） ， p （ an - ita ）兩種共聚物為基體時均出現金屬銅的沉積，二者金屬沉積相均呈現一定程度的梯度分佈形態，但p （ an - ita ）為基體時得到的晶體比較粗大，且隨其中ita的含量的增多得到粗糙晶體的數目增大，所制的pmgcf脆而硬，受外力沖擊時容易斷裂。 -
On the other hand, when using p ( an - mma - as ) as polymer matrix, the gradient distribution of copper in pmgcf is raisonne, the crystal is smaller and compacter than the former, the flexibility of pmgcf increase as the concentration of mma in copolymer increase, the size of copper crystal increase as as the concentration of ita in copolymer increase
P （ an - mma - as ）為基體時金屬梯度分佈較合理，金屬晶體細小而且緻密，而且所制的pmgcf柔韌性較好，隨mma含量的增多而柔韌性增大，隨其中的as的含量的增大，所得的金屬晶體尺寸變化與p （ an ita ）相似，但變化的趨勢較緩慢。
