V stat'e issleduetsya vliyanie funkcionalizacii uglerodnyh nanotrubok (UNT) na prochnostnye svoystva nanokompozitnyh kriogeley na osnove polivinilovogo spirta (PVS). Funkcionalizaciya UNT s pomosch'yu razlichnyh funkcional'nyh grupp napravlena na uluchshenie adgezii mezhdu nanotrubkami i polimernoy matricey, chto, v svoyu ochered', mozhet suschestvenno povysit' mehanicheskie harakteristiki poluchennyh kompozitov. V hode eksperimenta byli provedeny testy na predel prochnosti s razlichnymi koncentraciyami nemodificirovannyh, okislennyh (UNT-SOON), modificirovannyh polivinilovym spirtom (UNT-PVS) uglerodnyh nanotrubok. Rezul'taty pokazali, chto vvedenie UNT i UNT-SOON v kriogelevuyu matricu PVS privodit k znachitel'nomu uvelicheniyu prochnostnyh svoystv, odnako statisticheski znachimoe razlichie v prochnostnyh svoystvah kompozitov s UNT i UNT-SOON nablyudalos' tol'ko pri koncentracii 0,1%. V to zhe vremya, vvedenie UNT-PVS do koncentracii 0,5% takzhe povyshaet prochnostnye harakteristiki kriogeley, v to vremya kak dal'neyshee uvelichenie koncentracii UNT-PVS privodit k snizheniyu predela prochnosti.
