Abstract
Description
Преимуществом полученного электрофотографического материала вл етс то, что подобные смешанные слои легко получить из смешанных растворов , а в специальных случа х из сплавов, а добавки/ повышающие чувствительность , ввод т относительно в больших количествах без видимого расслоени полимеров, благодар чему образуютс прозрачные слои. Кроме того, повышаетс химическа стабильность и стабильность при хранении.The advantage of the obtained electrophotographic material is that such mixed layers are easily obtained from mixed solutions, and in special cases from alloys, and additives / sensitivity enhancements are introduced relatively in large quantities without visible stratification of polymers, due to which transparent layers are formed. In addition, chemical and storage stability is improved.
Получение электрофотографического материала иллюстрируетс следующими примерами.The preparation of the electrophotographic material is illustrated by the following examples.
Пример 1. 9,64 г поликсилилидена .(мол.вас 2500 г/моль) раствор ют в 300 мл хлороформа и перемешивают с раствором 0,36 г 1 4-бис-(с -цианостирил ) -2, Б-диметоксибензола в 200 мл толуола. Этот раствор нанос т на провод щий субстрат и после испарени растворител при 30115 С получают прозрачный фотопроводниковый слой толщиной около 2 мкм. Подобный слой можно зар дить с помощью короны до 350 В. При освещении 40 люкс в течение 1 с этот слой разр дитс до половины потенциала.Example 1. 9.64 g of polyxylylidene (mol. 2500 g / mol) is dissolved in 300 ml of chloroform and stirred with a solution of 0.36 g of 1 4-bis- (c-cyanosryryl) -2, B-dimethoxybenzene in 200 ml of toluene. This solution is applied to a conductive substrate and, after evaporation of the solvent at 30115 ° C, a transparent photoconductor layer is obtained with a thickness of about 2 microns. Such a layer can be charged with a corona up to 350 V. If it is illuminated at 40 lux for 1 s, this layer discharges to half the potential.
Пример 2.. На провод щий субстрат нанос т слой толщиной около 2 мкм из раствора 10,0 г поликсилилидена по примеру 1 в 500 мл Example 2. A layer about 2 microns thick was applied to a conductive substrate from a solution of 10.0 g of polyxylylidene of Example 1 in 500 ml
Пример 3. 9,23г сополимера поликсилилидена (мол.вес 4300 г/моль полученного из 50 мол.% 1,4-бис-(° -хлорбензил )бензола и 50 мол.% 2,5-диметоксиксилилендихлорида путем депидрагалогенизации, раствор ют с 0,77 г 1, 4-бис-(ci-цианостирил)-2, 5-диметоксибензола в 500 мл толуола.Example 3. 9.23 g of a polyxylylidene copolymer (mol. Weight 4300 g / mol of 1,4-bis- (° -chlorobenzyl) benzene obtained from 50 mol.% And 2,5 mol. 0.77 g of 1, 4-bis- (c-cyanostyryl) -2, 5-dimethoxybenzene in 500 ml of toluene.
Этот раствор нанос т на провод щий субстрат и после испарени растворител получают прозрачный фотопровод щий слой толщиной около 2 мкм. Подобный слой можно зар дить с помощью кроны до .350 в. При освещении 40 люкс слой разр дитс в течение 1 ,.5 с до половины потенциала.This solution is applied to a conductive substrate and, after evaporation of the solvent, a transparent photoconductive layer is obtained with a thickness of about 2 microns. Such a layer can be charged with a crown up to .350 in. When illuminated with 40 lux, the discharge layer is for 1, .5 s with up to half the potential.
