Coating ' s transparent and abrasive characters are measured by spectrophotometer and abrasion instrument and sway pole sclerometer. as a result, lacquer ' s abrasion - resistant performance improved 100 % adding 15 % nano - alumina. nano composite coating improved pmma base 2. 75 times
用分光光度計、耐磨儀及擺桿硬度計測定了塗料的透明性和耐磨性,添加15 %的納米al2o3 ,塗膜的耐磨性能提高了100 % ,納米復合塗料對底材有機玻璃的耐磨性能提高了2 . 75倍,可見光透過率在80 %左右。Prepared technical parameters were optimized by l9 ( 34 ) experiment analysis. a unique method for cleaning and drying of substrate - cleaning used by scour, drying used by infrared light was fished out by large numbers of experiment. chemical mechnism of zno thin film prepared by sol - gel technique was discussed by dta for the first time. by the measurements of sem, xrd and uvs, the thin film was analysed. the result proved that the thin film with strongly preferred orientation of c - axis perpendicular to the substrate surface which surface was homogenous, dense and crackfree was the crystalline phase of hexagonal wurtzite. the thin film was composed of plentiful asteroidal crystal which crystal dimension approximately 10 30nm. the average transmittance of thin film in visible region was above 90 %. the results of measurements else also proved that the thickness of single dip - coating was 75 240nm, this films resistivity was found to be 3. 105 102 3. 96 105 ? cm. the thickness and resistivity of thin film influenced by dope - content, withdrawal speed, pre - heat - treatment, anealing were reseached respectively
利用xrd 、 sem以及uvs光譜儀等分析方法對薄膜進行了研究,結果顯示,所制備的薄膜為六方纖鋅礦型結構,具有高c軸擇優取向性;表面均勻、緻密,薄膜材料由許多星狀晶粒組成,晶粒尺寸大約為10 - 30nm左右;薄膜可見光透過率平均可達90 % ;對薄膜厚度以及電學性能進行了測定后發現:單次鍍膜厚度約為75 - 240nm , al ~ ( 3 + )離子摻雜型氧化鋅薄膜的電阻率在3 . 015 102 - 3 . 96 103 ? cm范圍內;分別研究了摻雜濃度、提拉速度、預燒溫度、退火溫度等工藝參數對薄膜厚度和電阻率的影響。
